torrus_monitor
TORRUS_MONITOR(8) torrus TORRUS_MONITOR(8)
NAME
monitor - Torrus Monitor.
SYNOPSIS
torrus monitor --tree=TREENAME [options...]
DESCRIPTION
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.
OPTIONS
--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.
FILES
/etc/torrus/conf/torrus-siteconfig.pl
Torrus site configuration script.
/var/log/torrus/monitor.TREENAME.log
Monitor's log for the tree TREENAME.
