|
|
|
|
1.11 (2014-11-22)
|
|
|
|
- When within a MultiCheck a single check causes an exception, the
|
|
other checks are now still present in the output of check_jmx4perl
|
|
and the overall check has the status UNKNWON (#40)
|
|
- Minor fixes on the WebSphere Checks
|
|
- Fixed issue when calling check_jmx4perl for an operation without argument (RT##98166)

|
|
- Fixed warning when using MBeanName (#31)
|
|
- Fixed BaseMBean and formatting
|
|
- Fixed relative checks when using MBean patterns
|
|
- Added formatter '%q' to include a ratio of value to base without
|
|
multiplying by 100 like for '%r'
|
|
- Disabled OpenPGPVerifier since it doesn't support the new digest
|
|
algorithms used for signing the Jolokia artefacts (#32)
|
|
- Don't set ssl_opts if on LWP < 6 (#28)
|
|
- Fixed BaseMBean and BaseAttribute config directives (#25)
|
|

|
|
- Fixed check definition for 'wls_channel_connections (RT#89107)
|
|
- Changed check 'memory_gc_time' to be a relative check to measure the
|
|
relative amount taken for the GC. If you use this check (or a sub-check of this)
|
|
YOU NEED TO UPDATE YOUR THRESHOLDS (and regenerate the pn4p graphics) if you use this
|
|
check directly
|
|
- Fixed bug when using 0 thresholds in checks using parent checks (#38)
|
|
- Added support for '*' wildcard when navigation with cd for j4psh
|
|
- Fixed bug with check inheritance and check parameters which contain parantheses
|
|
- Added an option "MultiCheckPrefix" for "Checks" in order to specify the prefix
|
|
for multi checks
|
|
- Added config options "SummaryOk" and "SummaryFailure" for allowing to fine tune
|
|
multi check output (#24)
|
|
- "Argument" can be used in "Operation" config checks for providing arguments to
|
|
Nagios checks which are based on operations (#27)
|
|
|
|
1.07 (2013-04-16)
|
|
- Added more robust timeout for the Jmx4Perl Agent (requires Sys::SigAction)
|
|
- SSL Host key verification switched off when connecting via SSL
|
|
- Fixed issue with quoting in j4psh (#14)
|
|

|
or check_jmx4perl (#16)
|
|
- "jolokia" can do 'repack' and 'info' also when not being connected
|
|

|
|
or <Check> (#19)
|
|
- Added new option '--perfdata true|false' (PerData false in configuration) for
|
|
switching of performance data. Also, for string checks performance data is
|
|

|
1.06 (2012-10-13)
|
|
- A a scripting mode to check_jmx4perl which allows putting in arbitraty
|
|
Perl code for extracting the value to match against
|
|
- weblogic specific Nagios checks added
|
|
- Added name as optional parameter for Nagios checks in tomcat.cfg (thanks Wolfgang)
|
|
- When a multi checks fails, then the name of the check is added instead of its definition
|
|
key. This allows for better direct usage of predefined checks in own multi checks.
|
|
- If neither a CRITICAL nor a WARNING threshold is provided, then
|
|
the check always returns OK. This is especially useful when the
|
|
motivation is to only collect performance data.
|
|
|
|
1.05 (2012-04-22)
|
|
- Added Time::HiRes as dependency to check_jmx4perl
|
|
- Replaced XML::Tidy with XML::Twig and relaxed version number
|
|
requirement on Module::Build
|
|
- RT#72413: Fixed configuration in threads.cfg
|
|
- Updated documentation for 'jmx4perl' (--method and --legacy-escape
|
|
explained)
|
|
- Bundled Module::Build 0.34 in order to improve the installation
|
|
experience
|
|
- j4psh: Added 'pwd' command
|
|
- j4psh: Added options -a (attributes) and -o (operatiosn) to the 'ls'
|
|
command which now also supports wildcards for filtering
|
|
|
|
1.04 (2011-11-27)
|
|
- Fixed serious (and stupid) bug for jmx4perl and j4psh when printing
|
|
out scalar values.
|
|
|
|
1.03 (2011-11-23)
|
|
- Fixed stupid last minute bug.
|
|
|
|
1.02 (2011-11-23)
|
|
- Fix for threshold with 0 value in check_jmx4perl
|
|
- Fix automatic detection of the largest version number for Jolokia
|
|
agents in with the format 1.0.1 when downloading with 'jolokia'
|
|
- Fixed printing of boolean values for jmx4perl and j4psh for
|
|
complex data structures (finally)
|
|
- Added option '--option key=val' to jmx4perl and j4psh for tuning the
|
|
output format of these tools (known keys: format,booleans,indent)
|
|
- Added '--target' to j4psh so that it can operate against a JSR-160
|
|
proxy
|
|
|
|
1.01 (2011-10-25)
|
|
- Fixed 'jolokia' to load the new renamed jvm agent.
|
|
- Fixed issue when printing boolean values with jmx4perl
|
|
- Fixed issue with LWP as old as 5.805
|
|
- Bumped required version of Module::Build to 0.38 in order to cope
|
|
with messed up version number of XML::Tidy.
|
|
- j4psh works now with Getopt::Long before 2.38
|
|
|
|
1.00 (2011-10-3)
|
|
- Changed escaping as introduced by Jolokia 1.0. If talking with
|
|
Jolokia < 1.0, use the option '--legacy-escape' must be used if
|
|
using GET requests with MBeans containing / in the
|
|
name. JMX::Jmx4Perl knows this option as well
|
|
('legacy-escape'). j4psh does the detection automatically,
|
|
jmx4perl, check_jmx4perl and cacti_jmx4perl know about the new
|
|
configuration option.
|
|
- That's 1.0
|
|
|
|
0.95 (2011-8-21)
|
|
- Fixed Cacti output when labels contains spaces
|
|
- Tuned ancient Perl coding style (thanks, datamuc)
|
|
- Fixed problem with jolokia and PGP verification in non-english
|
|
environments.
|
|
- Fixed 'search' command which now really returns undef if nothing
|
|
is found (and not a ref to an empty array). That will also fix some
|
|
detectors when the 'info' command is used.
|
|
|
|
0.92 (2011-5-9)
|
|
- Fixed bug in pack specification (encryption) which is not available for
|
|
Perl 5.8 (and which broke Jmx4Perl for Perl 5.8)
|
|
|
|
0.91 (2011-5-6)
|
|
- Added --unknown-is-critical option to map all UNKNOWN to CRITICAL values (RT#67899)
|
|
- Added jmx4perl back to the build process, which was forgotten in 0.90
|
|
- Fixed bug RT#67815 which was caused by an invalid replacement of placeholder
|
|
for certain cases (i.e. is during parent check definition resolving
|
|
($0,$1) needs to be replaced by ($1,$2) which ended up falsely as ($2,$2)).
|
|
- Implemented --timeout option for check_jmx4perl, which is a pure HTTP timeout
|
|
for the communication between the Nagios checks and the Jolokia agent (RT#67821)
|
|
- Added a possibility to store encrypted passwords in the configuration file.
|
|
Please note, that this is *not* secure and only prevents casual attacks, since
|
|
the password needs to be symmetrically decrypted before passing it to the server.
|
|
In order to create an encrypted password, use 'jmx4perl encrypt <passwd>'.
|
|
- Fixed RT#67772 which prevented the proper count of failed checks for non-relative
|
|
checks within multi checks
|
|
|
|
0.90 (2011-4-11)
|
|
- Tuned Build.PL so that scripts can be added conditionally.
|
|
- Fixed normalization issue with negative delta check values.
|
|
- Support for new JSON serialization style of Jolokia 0.90 added.
|
|
(i.e numbers and booleans are not returned as plain strings anymore
|
|
but as Long, Double, true/false. Null is returned as JSON-null.
|
|
If you have trouble with boolean checks in check_jmx4perl, please
|
|
update to this jmx4perl version.
|
|
- Added 'jolokia' for downloading and managing Jolokia agents
|
|
- Removed jmx4perl Java agent source and agent since jmx4perl now uses
|
|
Jolokia as agents (www.jolokia.org)
|
|
- Added 'cacti_jmx4perl', a tool for gathering Cacti data (www.cacti.net)
|
|
It is heavily based on 'check_jmx4perl' (without threshold handling).
|
|
|
|
0.75 (2011-2-4)
|
|
- Fixed typo in POD documentation which prevented a successful
|
|
build in some situations
|
|
|
|
0.74 (2011-1-16)
|
|
- Fixed problem with multichecks including operation-checks with
|
|
arguments. Specifying them in a configuration has been falsely
|
|
ignored.
|
|
- Added '--method' command line option and 'Method' check
|
|
configuration option to check_jmx4perl for selecting the prefered
|
|
HTTP request method.
|
|
- Fixed normalization of time values (RT #63545)
|
|
- Improved default check_jmx4perl configuration (in hopefully a backward
|
|
compatible way)
|
|
- Multi check service summary now contains the name of failed services
|
|
- Fixed problems with a single '/' argument (RT #62915)
|
|
|
|
0.73 (2010-11-03)
|
|
- Fixed RT #61903 which occurs when the same check is referenced
|
|
multiple times (with potentially different parameters) in a
|
|
multicheck scenario.
|
|
- Fixed RT #62342: Perl warning when using operations and not --name
|
|
in check_jmx4perl
|
|
- Added --method to jmx4perl, config option 'method' for JMX::Jmx4Perl
|
|
in order to allow a default HTTP Method to use.
|
|
- Changed request command constant 'VERSION' to 'AGENT_VERSION' in
|
|
order to avoid conflicts with the usual versioning conventions for
|
|
Perl Modules. This is an API change, so in case you are using requests
|
|
with the constant VERSION you should change this to AGENT_VERSION
|
|
- Fixed issues when browsing with less in j4psh
|
|
- Extended config handling in j4psh to allow includes
|
|
|
|
0.72 (2010-9-24)
|
|
- Fixed problem with quotes in the config when using "Value"
|
|
and/or "Base".
|
|
- Adapted tomcat.cfg to be more flexible (e.g. replaced 'Catalina'
|
|
domain part by a wildcard).
|
|
- Fixed bug for merged MBeanServers when using multiple attributes
|
|
and/or MBean patterns for a READ request
|
|
- Fixed broken --target, --target-user and --target-password for
|
|
check_jmx4perl (same for --proxy and co.)
|
|
- Tuned output of complex data in j4psh
|
|
- Unwrap an MBeanException to use the target exception for an error
|
|
message
|
|
- Agent tested with Mule 3.0
|
|
|
|
0.71 (2010-8-16)
|
|
- Added 'ns' as unit (CpuThreadTime returns nano seconds)
|
|
- Fixed quoting of performance data in so far to let
|
|
Nagios::Plugin the complete control
|
|
- Fixed '--color' option and UseColor config directive
|
|
(section: <Shell>) to j4psh
|
|
- Added detection of a suitable pager for j4psh
|
|
- Fixed bug in server configuration when using old style syntax
|
|
|
|
0.70 (2010-7-10)
|
|
- Extended configuration syntax for check_jmx4perl as an alternative to
|
|
command line options
|
|
+ Parameterized checks
|
|
+ Default values for parameters
|
|
+ Multichecks (one HTTP request, many JMX requests)
|
|
+ Check-Inheritance
|
|
+ Predefined checks for certain environments (as sample configuration files)
|
|
+ Added null value check, can be tuned with --null
|
|
- Added '--value' as a shortcut for --mbean/--attribute/--value
|
|
- Better documentation for check_jmx4perl (30 extra pages)
|
|
- <Server> sections are now named blocks, taking the server name as block
|
|
name (similar to <Check>). The old syntax with an "Name" argument is
|
|
still support but must not be mixed with the new syntax.
|
|
- Path elements containing '/' can now be escaped with '\/'
|
|
- j4p-osgi-bundle including pax-web-bundle so only a single bundle
|
|
is needed for deploying (when no OSGi HttpService is installed)
|
|
- Relaxed version requirements on core and compendium OSGi classes
|
|
for j4p-osgi bundle.
|
|
- Changed access restrictions (j4p-access.xml):
|
|
+ <allow> and <deny>
|
|
+ Wildcards (*) for attribute and operation names
|
|
+ WARNING: Semantics of MBean specification has changed. Please
|
|
read the comments in j4p-access.xml.template
|
|
+ Add logging (level info) for printing out which security policy
|
|
is used
|
|
- Started to add a java client library
|
|
- j4psh beta version added
|
|
- Agent:
|
|
+ Switched from JUnit to TestNG for testing because of
|
|
support of testing groups
|
|
+ New servlet init parameter option 'mbeanQualifier' to allow
|
|
multiple j4p-servlet in a single application server
|
|
|
|
0.65 (2010-3-30)
|
|
- A JDK 6 java agent added for exporting the j4p protocol via
|
|
HTTP/JSON.
|
|
- Extended READ operation to support MBean patternames and multiple
|
|
attributes with a single request
|
|
- Renamed 'max_depth', 'max_list_size','max_objects' as processing
|
|
configuration parameters to 'maxDepth', 'maxCollectionSize' and
|
|
'maxObjects' respectively for consistencies sake.
|
|
- Bug fix: POST request respect these parameters as well now
|
|
- Added 'ignoreErrors' request option in order to allow a bulk read
|
|
to succeed even if single read fails. In this case, the valu will
|
|
- 'search' returns properly escaped MBean Names if unsafe characters
|
|
are used.
|
|
- For GET request, instead of pathinfo a query with parameter 'p'
|
|
can be used as alternative. This works around certain issues with
|
|
special path handling with certain app-servers (e.g. Tomcat).
|
|
- JMX::Jmx4Perl::Request and JMX::Jmx4Perl::Agent hardened in order
|
|
to be more smart with unsafe MBean Names and detect automatically
|
|
the most convenient HTTP Request method (if not explicitely set)
|
|
- Added more unit and integration tests.
|
|
- Added VERSION command to JMX::Jmx4Perl to get to agent and
|
|
protocol version
|
|
- Fixed error handling for bulk requests. Now each request object
|
|
will return an associated response object even in the error case.
|
|
- Fixed JMX::Jmx4Perl::info for IBM JVMs
|
|
- Added JMX::Jmx4Perl->parse_name() for splitting up a given MBean
|
|
object name into its parts
|
|
|
|
0.60 (2009-02-28)
|
|
- OSGi bundle (including dependencies) for exposing JSON export via
|
|
the OSGi HTTP-Service. It's in agent/modules/j4p-osgi.
|
|
- Refined error handling
|
|
- Removed legacy JDK 1.4 support. 0.36 is the one and only version
|
|
for which the JDK 1.4 backport has been tested to some amount.
|
|
- Added support for overloaded JMX operations for 'list' and 'exec'
|
|
- 'read' operation can now be used without attribute name in which
|
|
case the value of all attributes is returned. This can be used
|
|
directly with JMX::Jmx4Perl and the frontend jmx4perl.
|
|
- Support for Resin 3.1 added
|
|
- 'exec' operation can now deal with simple array arguments. Within
|
|
the perl modules, give an array ref for an array argument. This
|
|
gets translated to a comma separated list of values in the
|
|
string. For string array this works only with simle content
|
|
(i.e. no element containing a ',')
|
|
|
|
0.51 (2009-12-30)
|
|
- Quickfix for a badly packaged agent/j4p.war
|
|
|
|
0.50 (2009-12-24)
|
|
- Protocol of j4p.war has been extended to enable proxy mode
|
|

|
|
- Added Mule agent. Use maven to build it in agent/modules/j4p-mule
|
|

|
|
fetching java artifacts from the labs.consol.de maven repository.
|
|
- Cleaned up and updated Manual.pod
|
|
|
|
0.40 (2009-11-14)
|
|
- Extended protocol to allow for JSON requests via POST in addition
|
|
to pure URL based requests via GET
|
|
- Implemented bulk requests: JMX::Jmx4Perl->request() can now take a
|
|
list of JMX::Jmx4Perl::Request objects in which case it will
|
|
return a list of JMX::Jmx4Perl::Response objects (instead of a
|
|
single, scalar, response when used with a single request)
|
|
- Support for Glassfish V3 Preview, Jonas 5.1 and Jetty 7.0.0
|
|
|
|
0.36 (2009-10-30)
|
|
- Added <remote> to j4p-access.xml for restricting
|
|
access to certain hosts or subnets only.
|
|
- Added support for a JDK 1.4 agent war. The feature base for
|
|
this agent is frozen. It might even vanish in the future.
|
|
You need a JDK 1.4 agent for running within Weblogic 8.1
|
|
- Cleaned up j4p agent with help of sonar and associated
|
|
metric checkers like PMD, check_style and FindBugs.
|
|
- Added support for config files in jmx4perl and JMX::Jmx4Perl
|
|
which allows for shortcuts for agent URL as well as storing
|
|
user and credentials information.
|
|
- Fixed some bugs
|
|
|
|
0.35 (2009-08-15)
|
|
- Added example 'threadDump.pl'
|
|
- Fixed bug when serializing floats and doubles.
|
|
- check_jmx4perl:
|
|
* Added support for checking string and boolean values
|
|
* Escaping performance data
|
|
* Include units-of-measurement in the plugin output
|
|
* Custom labeling of plugin output
|
|
* Perfdata contains always absolute values, even when
|
|

|
|
|
|
0.30 (2009-07-31)
|
|
- Fixed permission issue while running 'Build dist'
|
|

|
|
bash history for repeated usage.

|
|
- Added '--proxy' for check_jmx4perl and jmx4perl
|
|
- check_jmx4perl:
|
|
+ Refactored to work within the embedded Nagios Perl interpreter
|
|
(ePN)
|
|
+ use relative values in the range from 0 to 100%
|
|
(for --critical and --warning) instead of [0..1]
|
|
+ Renamed '--base-value' to '--base' since it can take now
|
|
absolute values (numbers) or "mbean/alias/path" tuples as an
|
|
argument in addition to alias names.
|
|
+ Added '--operation' which allows for using return values of
|
|
operations as check values
|
|
+ Added ~ 50 integration tests
|
|
