Check of dependend parent and child-processes

Hi all,

I try to check for a process on a SLES server and for at least two child processes of that parent process with the “procs” check_command. There have to be at least 2 child processes running , otherwise the application will be very slow.

The process table looks like:

ps -ef | grep 7451
caadmin   7451     1  0 Aug09 ?        00:00:00 ca_rsopsv
caadmin   7453  7451  0 Aug09 ?        00:00:28 -p 4 -n 200000052 -v 1
caadmin   7457  7451  0 Aug09 ?        00:00:00 -p 4 -n 200000053 -v 1
caadmin   7461  7451  0 Aug09 ?        00:00:00 -p 4 -n 200000054 -v 1
caadmin   7465  7451  0 Aug09 ?        00:00:00 -p 4 -n 200000055 -v 1

On the host I’ve configured:

  vars.procs["ca_rsopsv"] = {
    procs_argument = "ca_rsopsv"
  }
  vars.procs["children of ca_rsopsv"] = {
    procs_ppid = "7451"
  }

whereas the service is configured like:

apply Service "Process: " for (procs => config in host.vars.procs) {
  import "generic-service"
  check_command = "procs"
  command_endpoint = host.name
  vars += config
  assign where host.vars.os == "SLES"
  ignore where host.vars.noagent
}

That works if I know the PPID (here: 7451) already. Is there a way to get the PID of the first process “ca_rsopsv” in order to put it as variable in the check of the child processes?

Thanks for help!

Bye
Stephan
