NAME

snmp__cpuload - Munin plugin to monitor CPU usage by use of SNMP.

APPLICABLE SYSTEMS

Any SNMP-capable device that reports the HOST-RESOURCES-MIB::hrProcessorLoad OID.

CONFIGURATION

As a rule SNMP plugins need site specific configuration. The default configuration (shown here) will only work on insecure sites/devices.

   [snmp_*]
        env.version 2
        env.community public

In general SNMP is not very secure at all unless you use SNMP version 3 which supports authentication and privacy (encryption). But in any case the community string for your devices should not be "public".

Please see 'perldoc Munin::Plugin::SNMP' for further configuration information.

INTERPRETATION

The average, over the last minute, of the percentage of time that this processor was not idle.

MIB INFORMATION

This plugin requires support for the HOST-RESOURCES-MIB (RFC 2790). It reports the contents of the hrProcessorLoad OID for each entry in hrProcessorTable.
