Monitor JVM

[javim]

Is Pandora able to monitors a JVM (Java Virtual Machine)?

Thanks in advance.

In which OS? Which is exactly the kind of monitoring you are looking for, that is, what are the parameters you want to analyze?

[javim]

It would be in Red Hat EL5. Im not sure about the parameters I want to analyze. They could be memmory usage, etc.

There is an utility from Sun (now Oracle :-D) that may help you (check that is installed in your system, command jps:

  http://java.sun.com/performance/jvmstat/

Usage:

If you make it work...:), adding it to the pandora agent is simple, just create a module that parses the output using your own shell skills (wc, cut, perl, sed, awk, tail...)

As an example:

module_begin
module_name jvmperf
module_type generic_data
module_exec jstat -gcutil $(jps |grep -v Jps|tail -1|awk '{print $1}') 1000 1
module_description JVM Performance
module_end
