Monitoring MIBs

Two Management Information Bases (MIBs) are provided with the N1 System Manager. These MIBs provide the data structure that third-party monitoring tools can use to retrieve the data from the N1 System Manager using SNMP, and provide the data structure that third party monitoring tools can use to parse the SNMP notifications generated by the N1 System Manager. The MIBs can be found at /opt/sun/n1gc/etc/. These MIBs therefore enable you to use any SNMP client to query the N1 System Manager, and to listen for events using SNMP. The following MIBs are provided:

SUN-N1SM-INFO-MIB

This MIB describes the information that you can retrieve from the N1 System Manager by querying it using an SNMP client.

SUN-N1SM-TRAP-MIB

This MIB describes all of the events related to the N1 System Manager about which you can receive SNMP traps.

These MIBs are read-only. Using them requires a detailed knowledge of SNMP, although detailed descriptions of each object are provided in the MIBs. How you configure your monitoring system to start receiving traps depends on the nature of your monitoring system.

The MIBs are hardware independent.

Example 6–11 Receiving SNMP Traps

This example shows you how to use the simple UNIX trap listener, the snmptrapd command, to start receiving N1 System Manager traps.

# snmptrapd -m all -M /opt/sun/n1gc/etc:/usr/share/snmp/mibs -P

This example uses the snmptrapd command to start monitoring on default port 162 for SNMP traps. It also instructs the command to use the MIBs stored at /opt/sun/n1gc/etc and /usr/share/snmp/mibs to parse the contents of SNMP traps.
