You might want to jump on the nagios list, and ask about monitoring a process on a box. --- Kind Regards, Mr Gabriel (bberry mail)

Hi

Not a specific question on CentOS but in general about java processes running on Linux boxes.

I have a couple of java processes running on my linux boxes , They basically form a component of a bigger application. My point of interest is to monitor the resource usage of the java processes running on the linux box. So currently when i have these procs running on my box they show up as "java" in the ps -A command. I dont know for sure as to which java process belongs to which component of my appliacation. Hence what i do is add up all the resource utilization values for all java processes as my monitoring application relies on process names. So what i thought was , Is there a solution in linux or the way the JVM is initiated can we have process names different for different java processes. To be more specific if i have two java processes running in my system , in order to identify them properly can i have it running as java_1 or java_2 or something in those lines.

Please let me know if its possible.

if you can use the 'f' option in your ps command, you will get the arguments used to start the JVM. This may provide you with enough information to distinguish between them them

e.g.: ps -Af | grep java

identify them properly can i have it running as java_1 or java_2 or

as far as I know, it is not (easily) possible

You could give a try to the jconsole tool which comes with the JDK (in package java-1.6.0-openjdk-devel), it allows you to monitor Java processes precisely (either local or remote via JMX).

The Eclipse TPTP project also provides a lot of tools, but this would probably be an overkill in your case.

Add a -Darbitrary_string into your java commands.

Unless you are very unlucky with your arbitrary string, these will be passed to the java engine as parameters and will be ignored by the rest of the application. Then you can use this to pin the process in ps output.
