The Sentry daemon process (sentryd) monitors the PMAC application processes and
attempts to restart them automatically if a failure occurs.
By default, Sentry is configured to run in
Active mode. In
Active mode, if
sentryd determines that any or all of
the processes are not present in that table, it restarts the process(es) within
5 seconds. In
Passive mode,
sentryd does not restart any processes
that stop running on the host.
Additionally, Sentry automatically sends a request to the PMAC server to look at the status of each process. PMAC queries Sentry to determine process status and displays the status information in the PMAC GUI on the Sentry Process Control page (accessible on the main menu under ).
