Monitoring Using SNMP

An SNMP agent that is used for data retrieval is provided in the N1 System Manager software:

• If the management server is running the N1 System Manager on the Solaris OS, the SNMP agent that is used for data retrieval is based on the Sun Management Center 3.5 software SNMP agent.

• If the management server is running the N1 System Manager on Linux, the SNMP agent that is used for data retrieval is based on the Sun Management Center 3.6 Linux SNMP agent.

The default SNMP port for the agent for the monitoring feature is port 161. Changing the port number from the default is not supported in this release.

The SNMP agent is deployed when operating systems are provisioned on to servers that are managed by the N1 System Manager. The N1 System Manager passively listens for the traps generated by the SNMP agent whenever there is a threshold breach. In case the traps generated by the SNMP agent are lost, the N1 System Manager also performs two types of polling-based monitoring as a backup:

• Accessibility monitoring makes sure that the N1 System Manager can access the OS agent.

• Status monitoring periodically retrieves the current status from the SNMP agent and reports if the status is not OK.
