If it is linked to snmpdv3ne or snmpdv3e, then the relevant config file is /etc/snmpdv3.conf, not /etc/snmpd.conf. (The active snmp agent is controlled by snmpv3_ssw. snmpv3_ssw -n will switch to the non-encrypted, v3 agent.)
To allow AIX monitoring, you just need to ensure that the config file (snmpd.conf or /etc/snmpdv3.conf) allows the LogicMontor collector to query the system.
Ensure that the collector has access with the community you expect, and that all views are included.
Ensure that any line such as:
VACM_VIEW defaultView 1.3.6.1.4.1.2.6.191 - excluded -
is changed to included:
VACM_VIEW defaultView 1.3.6.1.4.1.2.6.191 - included -
Then restart all the snmp services:
stopsrc -s snmpd;stopsrc -s dpid2;stopsrc -s aixmibd;stopsrc -s hostmibd;stopsrc -s snmpmibd
startsrc -s snmpd;startsrc -s dpid2;startsrc -s aixmibd;startsrc -s hostmibd;startsrc -s snmpmibd
If you are not receiving data for CPU, memory, etc:
Ensure hostmibd, snmpmibd and aixmibd are not commented out in /etc/rc.tcpip
Ensure that snmp configuration allows connections from 127.0.0.1 with public community (or the appropriate community if you’ve changed that used by aixmibd away from the default.) (Note: the subdaemon’s actually connect to hostname “loopback” – so make sure that correctly resolves to 127.0.0.1)
Ensure aixmibd is running: lssrc -s aixmibd
Check /var/tmp/aixmibd.log to see whether aixmibd has correctly registered with the snmpd system, and for clues as to why not.
