lm-sensors Subagent

This subagent can be used to read hardware status using lm_sensors package.

Pre-requirements

Package lm_sensors should installed and configured properly. Output of sensors command should produce meaningful output. Example:

Provided Parameters

When loaded, lm_sensors subagent adds the following parameters to agent:

Parameter	Description
LMSensors.Value("chip", "label")	Current value returned by hardware sensor

Configuration file

All configuration parameters related to lm_sensors subagent should be placed into *LMSENSORS section of agent's configuration file. The following configuration parameters are supported:

Parameter	Format	Description	Default value
UseFahrenheit	Boolean	If set to "yes", all temperature reading will be converted to fahrenheit	no
ConfigFile	String	Path to sensors.conf	none, use system default (usually /etc/sensors3.conf)

Configuration Example

MasterServers = netxms.demo
SubAgent = lmsensors.nsm

*LMSENSORS
UseFahrenheit = yes
ConfigFile = /etc/sensors.netxms.conf
