TORRUS_COLLECTOR(8)						      torrus						       TORRUS_COLLECTOR(8)

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.

FILES

       /etc/torrus/conf/torrus-siteconfig.pl
	   Torrus site configuration script.

       /var/log/torrus/collector.TREENAME.log
	   Collector's log for the tree TREENAME.

       /usr/share/torrus/xmlconfig/snmp-defs.xml
	   Basic variable definitions for the SNMP collector.
