       collector - Torrus data Collector.


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


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

       Collector cycle scheduling is controlled by two parameters defined for
       each individual configuration leaf: "collector-period" and
       "collector-timeoffset". See the Torrus Configuration Guide for more

       The number of OID (Object IDentifier) variable bindings sent by
       Collector is controlled by the datasource parameter
       "snmp-oids-per-pdu".  It is set to a default value of 40 in
       snmp-defs.xml, and may be overwritten at the host level.


           Defines the collector instance. A single tree can allow more than
           one collector instance. The number of instances is defined in "run"
           hash in the’s %Torrus::Global::treeConfig.  If
           the number of instances is more than one, this option is mandatory.
           The collecting job is split between the instances, and normally all
           instances should be started by the startup scripts. The tree should
           be re-compiled after the number of instances is changed in the
           siteconfig.  In the example below the tree tree_A will be served by
           three collector instances:

             %Torrus::Global::treeConfig = (
               'tree_A' => {
                 'description' => 'The First Tree',
                 'xmlfiles' => [qw(a1.xml a2.xml a3.xml)],
                 'run' => { 'collector' => 3, 'monitor' => 1 } },

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

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

           Instructs the collector process to continue running even if no
           collector datasources are defined in the tree. In this case, the
           process will check once per hour if the configuration has changed.

           Sets the log level to debug.

           Sets the debug level to info.

           Displays a help message.
