Linux::Process Health settingsC.5.11. Linux::Process RunningThe Linux::Process Running probe verifies the specified process is functioning properly. It countseither processes or process groups, depending on whether the Count process groups checkbox isselected.By default, the checkbox is selected, thereby indicating the probe should count the number of processgroup leaders independent of the number of children. This allows you, for example, to verify thattwo instances of the Apache HTTP Server are running regardless of the (dynamic) number of childprocesses. 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 theentry of a command name. If no command name or PID is entered, the error Command not foundwill 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.Field ValueCommand namePID fileCount process groups (checked)Timeout* 15Critical Maximum Number RunningCritical Minimum Number RunningTable C-25.
