=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This script is a simplified version of C<check_jmx4perl> which does not check
|
||
|
|
for thresshold and prints out the measured data in a simplified format, which
|
||
|
|
can be used by Cacti (L<www.cacti.net>). For single checks, it simply returns
|
||
|
|
the number measured, for multi checks, the numbers are returned with labels and
|
||
|
|
space separated. See L<check_jmx4perl/"Multichecks"> for more about
|
||
|
|
multichecks.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
$ cacti_jmx4perl --url http://localhost:8080/jolokia --alias MEMORY_HEAP_USED
|
||
|
|
15308376
|
||
|
|
|
||
|
|
$ cacti_jmx4perl -u http://localhost:8080/jolokia --config config/memory.cfg --check memory
|
||
