------------------
Here are all the changes since Nagios 2.x:
* Adaptive monitoring:
- Check timeperiod can now be modified on-the-fly
* Notification changes:
- Added first_notification_delay to host and object definitions to delay first notification
- Notifications are now sent out when flap detection is disabled on a host/service-specific
or program-wide basis ($NOTIFICATIONTYPE$ macro = "FLAPPINGDISABLED")
- Notifications can now be sent out when scheduled downtime starts, ends, and is cancelled. The
$NOTIFICATIONTYPE$ macro will be set to "DOWNTIMESTART", "DOWNTIMEEND", or "DOWNTIMECANCELLED",
respectively. In order to receive downtime notifications, specify 's' or 'downtime' in contact, host,
and/or service notification options.
* Object changes:
- Added ability to use multiple template names (separated by commas) in object definitions
- Added ability to null out optional character directives in object definitions (using 'null' without quotes)
- Added hostg/service/contactgroup_members directives to host/service/contactgroup definitions,
respectively, for allowing including host, service, or contact members from "sub" groups.
- Added support for custom variables in host, service, and contact definitions
- Added host_notifications_enabled, service_notifications_enabled, can_submit_commands to contact definitions
- Added optional display_name directive to host and service definitions
- Removed serviceextinfo definitions and merged variables with service definitions
- Removed hostextinfo definitions and merged variables with host definitions
- Services inherit contactgroups, notification interval, and notification period from associated host if not specified
- Service escalations inherit contactgroups, notification interval, and escalation period from associated service if not specified
- Host escalations inherit contactgroups, notification interval, and escalation period from associated host if not specified
- Host, service, host escalation, and service escalation definitions now support a 'contacts' directive, along with 'contact_groups'
- Service dependencies with blank dependent host/hostgroup names will create "same host" dependencies
* Performance optimizations:
- Added ability to precache object config files
- Added ability to exclude object relationship and circular path
checks from verification process
* Check output:
- Multiline output support for host and service checks
* Macro changes:
- Added $LONGHOSTOUTPUT$ and $LONGSERVICEOUTPUT$ macros
- Added $TEMPPATH$ macro
- Removed $COMMENTDATAFILE$ and $DOWNTIMEDATAFILE$ macros
- Added $HOSTDISPLAYNAME$ and $SERVICEDISPLAYNAME$ macros
- Custom host/service/contact macros accessible via $_HOST<varname>$, $_SERVICE<varname>, or $_CONTACT<varname>$.
On-demand host/service macros for custom vars are working. Custom vars are also set as environment vars.
- On-demand service macros can contain and empty host name field. In this case, the name of the current host will be used.
- $HOSTNOTES$ and $SERVICENOTES$ macros may now contain macros themselves
* Flapping changes:
- Added flap_detection_options directive to host and service definitions to control which
states (i.e. OK, WARNING, UNKNOWN, and/or CRITICAL) are used in flap detection logic
- Percent state change and state history are now retained and recorded even when host/service
flap detection is disabled.
- Hosts and services are immediately check for flapping when flap detection is enabled program-wide.
- Hosts/services that are flapping when flap detection is disabled program-wide are now logged
* External command changes:
- Added PROCESS_FILE external command to allow processing of external commands found in
an external (regular) file. Very useful for passive checks with long output or scripting.
- Custom commands can now be submitted to Nagios. Custom command names are prefixed with an underscore
and are not processed internally by the Nagios daemon. They may, however, be processed by NEB modules.
- External commands are now checked by default. Nagios 2.x and earlier did not check for external commands
by default.
* Status data changes:
- Contact status information is now saved (although it is not processed by the old CGIs)
* Retention data changes:
- Contact status information is now retained across program restarts
- Comment and downtime IDs are now stored across program restarts, should be unique unless reset
- Added retained_host/service_attribute_mask variables to control what host/service attribs are retained globally
- Added retained_process_host/service_attribute_mask variables to control what process attribs are retained
- Added retained_contact_host/service_attribute_mask variables to control what contact attribs are retained globally
* Downtime changes:
- Scheduled downtime entries are now stored in the status and retention files
* Comment changes:
- Comments are now stored in the status and retention files
- Non-persistent acknowledgement comments are now deleted when the acknowledgement is removed (instead of when Nagios restarts)
* Host check logic changes:
- Most host checks are now run asynchronously, in parallel!
- Scheduled host checks now help improve performance, instead of hinder it (if caching is enabled)
- Added cached_host_check_horizon option for enabling use of cached host check results
- Added enable_predictive_host_dependency_checks for enabling predictive checks of dependent hosts
- Added retry_interval to host definitions
- Added check_for_orphaned_hosts option and support for orphaned host checks
- Passive host check states can now be translated from their original DOWN/UNREACHABLE state if the
new translate_passive_host_results option is enabled
* Service check logic changes:
- 'parallelize' option in service definitions deprecated/no longer used
- Added cached_service_check_horizon option for enabling use of cached service check results
- Added enable_predictive_service_dependency_checks for enabling predictive checks of dependent services
* Dependency changes:
- Host and service dependencies can now have a timeperiod during which they're valid (dependency_period directive)
* Event broker changes:
- Updated NEB API version
- Modified adaptive program status callback
- Added adaptive contact status callback
- Added host/service precheck callbacks to allow modules to cancel/override internal host/service checks
* Embedded Perl changes:
- Added 'enable_embedded_perl' option to main config file to control whether epn is enabled/disabled
- Added support for perl plugins to specify whether or not they should be run under the epn... The
second to tenth line of a perl plugin may start with '# nagios: +epn' or '# nagios: -epn' to explicity indicate that it
should be run under the epn.
- Added 'use_embedded_perl_implicitly' option to main config file to determine whether or not perl
plugins will use the epn if they don't explicitly allow/disalow it
* CGI changes:
- Hostgroup and servicegroup summaries now show important/unimportant problem breakdowns like the TAC CGI
- Minor layout changes to host and service detail views in extinfo CGI
* Misc changes:
- More information given when testing scheduling (-s command line option)
- Removed fixed length restrictions for host names and service descriptions
- Plugin output length restriction bumped up to 4K
- Added temp_path directive to main config file for specifying temp directory
- Multiline output support for system commands via my_system()
- Added global event_id and notification_id vars that are at least unique during a single run of Nagios
- Default is now to check for orphaned services, rather than not
- Renamed service_reaper_frequency to check_result_reaper_frequency
- Fractional notification and check intervals are now supported (e.g. "3.5" minutes)
- Backslash chars are now used to escape command arguments that contain \ or ! characters
- Added 'external_command_buffer_slots' and 'check_result_buffer_slots' variables to specify size of internal buffers
- Added check statistics to status file, available via nagiostats for graphing in MRTG
- Added $HOSTGROUPNAMES$, $SERVICEGROUPNAMES$, $HOSTACKAUTHORNAME$, $HOSTACKAUTHORALIAS$, $SERVICEACKAUTHORNAME$,
and $SERVICEACKAUTHORALIAS$ macros

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Nagios 3.x README
-----------------
Nagios is a host/service/network monitoring program written in C and
released under the GNU General Public License. CGI programs are
included to allow you to view the current status, history, etc via
a web interface if you so desire.
Features:
1) Monitoring of network services (via SMTP, POP3, HTTP, PING, etc).
2) A plugin interface to allow for user-developed service monitoring methods.
3) Notifications when problems occur and get resolved (via email, pager,
or user-defined method).
4) Ability to define "event handlers" for proactive problem resolution
5) Web output (current status, notifications, problem history, log file, etc.)
6) Automatic log file rotation/archiving
For installation instructions, use a web browser to read the HTML documentation
in the html/docs subdirectory.
Visit the Nagios homepage at http://www.nagios.org for online
documentation, new releases, bug reports, information on the mailing
lists, etc.

* Nagios is a network monitoring tool that will check hosts and services

* recovers. Service and host monitoring is done through the use of external
* plugins which can be developed independently of Nagios.

/**********
Using dlopen() is great, but a real danger as-is. The problem with loaded modules is that if you overwrite the original file (e.g. using 'mv'),
you do not alter the inode of the original file. Since the original file/module is memory-mapped in some fashion, Nagios will segfault the next
time an event broker call is directed to one of the module's callback functions. This is extremely problematic when it comes to upgrading NEB
modules while Nagios is running. A workaround is to (1) 'mv' the original/loaded module file to another name (on the same filesystem)
and (2) copy the new module file to the location of the original one (using the original filename). In this scenario, dlopen() will keep referencing
the original file/inode for callbacks. This is not an ideal solution. A better one is to delete the module file once it is loaded by dlopen().
This prevents other processed from unintentially overwriting the original file, which would cause Nagios to crash. However, if we delete the file
before anyone else can muck with it, things should be good. 'lsof' shows that a deleted file is still referenced by the kernel and callback
functions continue to work once the module has been loaded. Long story, but this took quite a while to figure out, as there isn't much
of anything I could find on the subject other than some sketchy info on similar problems on HP-UX. Hopefully this will save future coders some time.
So... the trick is to (1) copy the module to a temp file, (2) dlopen() the temp file, and (3) immediately delete the temp file.

*
* SKIPLIST.C - Skiplist functions for use in Nagios event/object lists
*
* Copyright (c) 2008 Ethan Galstad
* Last Modified: 02-28-2008
*
* Notes:
*
* These function implement a slightly modified skiplist from that
* described by William Pugh (ftp://ftp.cs.umd.edu/pub/skipLists/skiplists.pdf).
* The structures and function were modified to allow the list to act
* like a priority queue for the Nagios event list/queue(s). Multiple nodes with
* the same key value are allowed on the list to accomodate multiple events
* occurring at the same (second) point in time. Implemented peek() and pop()
* functions to allow for quick event queue processing, and a method to delete
* a specific list item, based on its pointer, rather than its data value. Again,
* this is useful for the Nagios event queue.

# Check how to export functions from the broker executable, needed
# when dynamically loaded drivers are loaded (so that they can find
# broker functions).
# OS'es with ELF executables using the GNU linker (Linux and recent *BSD,
# in rare cases Solaris) typically need '-Wl,-export-dynamic' (i.e. pass
# -export-dynamic to the linker - also known as -rdynamic and some other
# variants); some sysVr4 system(s) instead need(s) '-Wl,-Bexport'.
# AIX 4.x (perhaps only for x>=2) wants -Wl,-bexpall,-brtl and doesn't
# reliably return an error for others, thus we separate it out.
# Otherwise we assume that if the linker accepts the flag, it is needed.

#####################
Nagios Contrib README
#####################
This directory contains various programs, scripts, etc. that
have been contribed by various people. Read the source code
if you want to find who did what.
Here is a description of what you'll find...
Conversion Programs:
--------------------
- convertcfg.c is a program to quickly convert old "host" config
files to the new template-based object config files. It can also
convert extended host information definitions. Type 'make convertcfg'
to compile the utility.
Additional CGIs:
----------------
- traceroute.cgi is (surprise) a CGI that allows you to do a traceroute
to a specific IP address. Simply do a 'chmod +x' to make it executeable
and place it in the CGI directory (i.e. /usr/local/nagios/sbin).
Requires Perl.
- daemonchk.c is a CGI contributed by Karl DeBisschop that can test to
see whether or not the Nagios process is running.
Miscellaneous Goodies:
----------------------
- htaccess.sample is a *sample* .htaccess file that can be used with
Apache to require password authentication for access to the web
interface.
- mini_epn.c is a mini embedded Perl interpreter that can be used to
test the feasibility of running various Perl plugins with the
embedded Perl interpreter compiled in.

# SUBMIT_CHECK_RESULT
# Written by Ethan Galstad (egalstad@nagios.org)
# Last Modified: 02-18-2002
#
# This script will write a command to the Nagios command
# file to cause Nagios to process a passive service check
# result. Note: This script is intended to be run on the
# same host that is running Nagios. If you want to
# submit passive check results from a remote machine, look
# at using the nsca addon.
#
# Arguments:
# $1 = host_name (Short name of host that the service is
# associated with)
# $2 = svc_description (Description of the service)
# $3 = return_code (An integer that determines the state
# of the service check, 0=OK, 1=WARNING, 2=CRITICAL,
# 3=UNKNOWN).
# $4 = plugin_output (A text string that should be used
# as the plugin output for the service check)
#
