Step 3: Collect SNMP information from the host

mm To get the SNMP-available information you added, execute this command from a host that has SNMP tools installed:

/usr/bin/snmpget -c public <hostname> system.sysLocation.0

Replace <hostname> with the name of the target host.

You should see location you provided. In this example, you would see:

SNMPv2_MIB::system.sysLocation.0 = STRING:\"server_room\"

The other options in the menu you were working in are:

/usr/bin/snmpget -c public <hostname> system.sysContact.0 /usr/bin/snmpget -c public <hostname> system.sysServices.0

The final .0 indicates you are looking for the index object. The word public is the name of the SNMP community that you did not alter.

If you need information about either of these or if you need explanations of SNMP syntax, tutorials are available at net-snmp.sourceforge.net.

About Notification and Event Monitoring Daemons

To monitor and log system events, the operating system runs several daemons that intercept application messages and log them or act on them.
