C.5.8. Linux::Process Counts by State
The Linux::Process Counts by State probe identifies the number of processes in the following states:
•
Blocked — One that has been switched to the waiting queue and the state of the process has been
switched to the waiting state.
•
Defunct — One that has terminated (either because it has been killed by a signal or because it has
called exit()) and whose parent process has not yet received notification of its termination by
executing (some form of) the wait() system call.
•
Stopped — One that has been stopped before its execution could be executed.
•
Sleeping — One that is in the Interruptible sleep state that can later be reintroduced into memory
and execution will resume where it left off.
Requirements — The Red Hat Network Monitoring Daemon (rhnmd) must be running on the monitored system to execute this probe.
