Monitoring Linux server using SNMPv1 not working

[zzBernie]

I have a CentoOS server running Zabbix agent 2.4, the same as the Zabbix server. I am monitoring items using the zabbix agent without any issues. But when I add an item and monitor it using SNMPv1, it is not displayed in the latest data area.

I used snmpwalk and snmpget to obtain the OID UCD-SNMP-MIB::dskAvail.1 which is disk space for the / file system. I tried creating a trigger, and it failed to work also.


Any ideas why monitoring SNMP on a linux server does not display any data in the latest data section?

Can you get value of UCD-SNMP-MIB::dskAvail.1 by snmpget or snmpwalk from Zabbix server?

If you can get it, please check your setting for item on Zabbix.
That setting are correct? (ex. OID, community, Type of information)

And, please check 'Info' column at item list screen.
If you move mouse pointer to red cross icon, error reason will display.

Yes, thank you, I had tried an snmpget from the zabbix server and it did not work. I had to allow the subnet the zabbix server resides on in the snmpd.conf file on the zabbix client server.
