Network/System monitoring plugins for nagios
Foldback nagios plugins
This module contains base implementations of two kinds of nagios plugin classes for python:
Generic nagios plugin for any kind of command
Nagios SNMP plugin, extending the base class
Installed to lib/foldback/plugins directory of your install prefix, a couple of ready to use pluings are also available. In sources, see directory data/plugins for the implementations.
Default nagios configuration for these plugins is installed to share/foldback/commands.cfg to be included in nagios.
Agents for net-snmp
Some of the plugins use net-snmp pass_persist script agents. Required agent scripts are in lib/foldback/agents directory with installed package and need to be added to snmpd.conf with correct OID prefix to be used.
Example from a FreeBSD host:
` pass_persist 18.104.22.168.4.1.2021.13.16 /usr/lib/foldback/agents/freebsd-temperatures pass_persist 22.214.171.124.4.1.2021.13.17 /usr/lib/foldback/agents/freebsd-kernel `
See the agent or plugin for expected prefixes to configure in snmpd.conf.
Using the plugin base classes is described in two examples of the source code tree:
describes using generic NagiosPlugin
describes using the NagiosSNMPPlugin variant
