Monitoring SMC with SNMP
SNMP (Simple Network Management Protocol) is a communication protocol that allows network administrators to monitor devices and diagnose network and hardware issues remotely.
SMC offers the SNMP service via the command smc-snmp.
This service is not enabled by default on the SMC server. If you do enable it, you do not need to enable it again after restarting the server, as this setting will be remembered.
The SMC server uses SNMP version 2c by default. You may however choose another version (version 1 or v3 USM) in the configuration file located in /etc/snmp/snmpd.conf.
Using the SNMP service
- Log on to the SMC server via the console port or in SSH.
- Enter one of the following commands:
| Action | Command |
|---|---|
| Enable the service | nstart snmpd ; update-rc.d -f snmpd remove ; update-rc.d snmpd defaults 98
|
| View the status of the service | /etc/init.d/snmpd status
|
| Restart the service | nrestart snmpd
|
| Disable the service | nstop snmpd ; update-rc.d -f snmpd remove
|
