Chapter 11. SNMP Configuration with the Red Hat High Availability Add-On

As of the Red Hat Enterprise Linux 6.1 release and later, the Red Hat High Availability Add-On provides support for SNMP traps. This chapter describes how to configure your system for SNMP followed by a summary of the traps that the Red Hat High Availability Add-On emits for specific cluster events.

11.1. SNMP and the Red Hat High Availability Add-On

The Red Hat High Availability Add-On SNMP subagent is foghorn, which emits the SNMP traps. The foghorn subagent talks to the snmpd daemon by means of the AgentX Protocol. The foghorn subagent only creates SNMP traps; it does not support other SNMP operations such as get or set.
There are currently no config options for the foghorn subagent. It cannot be configured to use a specific socket; only the default AgentX socket is currently supported.
