NAME

       collector - Torrus data Collector.

SYNOPSIS

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

DESCRIPTION

       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 details.

       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.

OPTIONS

       --instance=N
           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
           torrus-siteconfig.pl'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 } },
              );

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

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

       --runalways
           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.

       --debug
           Sets the log level to debug.

       --verbose
           Sets the debug level to info.

       --help
           Displays a help message.
