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.
