This script is a simplified version of check_jmx4perl which does not check for thresshold and prints out the measured data in a simplified format, which can be used by Cacti ( For single checks, it simply returns the number measured, for multi checks, the numbers are returned with labels and space separated. See "Multichecks" in check_jmx4perl for more about multichecks.


  $ cacti_jmx4perl --url http://localhost:8080/jolokia --alias MEMORY_HEAP_USED

  $ cacti_jmx4perl -u http://localhost:8080/jolokia --config config/memory.cfg --check memory
  Heap:15341168 Non-Heap:19450312

For the possible options and the configuration syntax, please refer to the documentation of check_jmx4perl. Certain options are not available for this Cacti Script, since they make no sense here:
