MONIT is an open source package used for monitoring the important
daemon services automatically initiated at startup. If a malfunction occurs,
MONIT provides actions such as alert, start, stop, and restart. To provide
these actions, applications must be registered with MONIT, and the
appropriate actions for each application must be specified.
The following system parameters are monitored: memory, CPU, and
device space usage. If usage of one of them passes a warning threshold
then a message is displayed. The warning and critical thresholds are
shown in
