A.5.11. Linux::Process Running
The Linux::Process Running probe verifies that 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 that 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 web 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 its command name or process ID. (PID). Entering a PID overrides the entry of a
command name. If no command name or PID is entered, the error Command not found is displayed and
the probe enters a CRIT ICAL state.
Requirements - T he Red Hat Network monitoring daemon (rhnm d) must be running on the monitored
system to execute this probe.

following metric:
Swap Free - The percent of swap memory currently free.
