monitor - Torrus Monitor.

torrus monitor --tree=TREENAME [options...]

This command starts the Monitor process for the tree TREENAME. By default it forks into a daemon, sets the log output file to /var/log/torrus/monitor.TREENAME.log, performs one monitoring cycle, and sleeps until the next cycle is scheduled. In daemon mode the log file can be reopened by sending it a SIGHUP signal.

Monitoring cycle scheduling is controlled by two variables whose values may be set in torrus-siteconfig.pl:

$Torrus::Global::monitorPeriod

Sets the period of the monitor run to a specified number of seconds. Default value is 300.

$Torrus::Global::monitorStartShift

Controls the shift of the start of monitoring cycle. Monitor will run at CWtime() mod Period + Shift, thus allowing the data to be updated during the shift period. Default value is 15.

--nodaemon

Prevents the process from becoming a daemon and sets the log to STDERR.

--runonce

Instructs the script to run once and exit. Implies --nodaemon.

--delay=N

Makes the daemon sleep for N minutes before starting the first cycle. This would happen on the daemon startup and also after each configuration recompilation. For example, when monitor and collector start simultaneously, the collector needs some time to retrieve the data being monitored.

--debug

Sets the log level to debug.

--verbose

Sets the debug level to info.

--help

Displays a help message.

/etc/torrus/conf/torrus-siteconfig.pl

Torrus site configuration script.

/var/log/torrus/monitor.TREENAME.log

Monitor's log for the tree TREENAME.
