C.5.11. Linux::Process Running
The Linux::Process Running probe verifies the specified process is functioning properly. It counts
either processes or process groups, depending on whether the Count process groups checkbox is
selected.
By default, the checkbox is selected, thereby indicating the probe should count the number of process
group leaders independent of the number of children. This allows you, for example, to verify that
two instances of the Apache HTTP Server are running regardless of the (dynamic) number of child
processes. If it is not selected, the probe conducts a straightforward count of the number of processes
(children and leaders) matching the specified process.
Specify the process by either command name or process I.D. (PID). Entering a PID will override the
entry of a command name. If no command name or PID is entered, the error Command not found
will be displayed and the probe will be set to a CRITICAL state.
Requirements — The Red Hat Network Monitoring Daemon (rhnmd) must be running on the moni-
tored system to execute this probe.
