Thread: Constantly "No values available"!

After the successful installation of OMSA, official scripts that should be used for Nagios are not working!

For example, here is the result of a simple request -

Code:

/usr/lib64/nagios/plugins/check_dell_status -H localhost --fan-data
Fan Information: No values available

Both check_dell_status and dell_health.py in the same directory are unable to get any information from the OpenManage.

Code:

/usr/lib64/nagios/plugins/dell_health.py --hostname=localhost --fan-data
Fan Information: No values available

* OMSA is installed correctly and can be managed though Web interface on port 1311
* Since this is PowerEdge 1950, firmware has been properly updated
* Nagios 3.x with plug-ins has been installed and configured successfully
* check_openmanage (snipurl.com/uupbl), alternative Nagios plugin is working on the same machine
* It seems that problem is within bad snmp communication (dell_health.py uses snmpwalk internaly)
* snmp daemon is running, and /etc/snmp/snmpd.conf been tweaked to be less restrictive

Here is the content of /etc/snmp/snmpd.conf -

Code:

com2sec notConfigUser   default         public 
group   notConfigGroup  v1              notConfigUser 
group   notConfigGroup  v2c             notConfigUser 
view    systemview      included        .1.3.6.1              127.0.0.1/16 
view    systemview      included        .1.3.6.1              192.168.0.0/16 
access  notConfigGroup ""      any       noauth    exact  systemview none none

Any ideas?

UPDATE:

After some more research, snmpd.conf is slightly changed -

Code:

com2sec publicsec default openmanage
group   notConfigGroup  v1              notConfigUser 
group   notConfigGroup  v2c             notConfigUser 
view    systemview      included        .1.3.6.1              127.0.0.1/16 
view    systemview      included        .1.3.6.1              192.168.0.0/16 
access notConfigGroup "" any noauth exact all all none 
smuxpeer .1.3.6.1.4.1.674.10892.1
trapsink 70.42.235.175 openmanage 

Still nothing...

Code:

/usr/lib64/nagios/plugins/dell_health.py --hostname=localhost --mem-data
Memory Information: TIMEOUT CONNECTING to agent

I found that it was necessary to enable snmp support in the data engine for openmanage. This was an important step that seemed to be missing from any documentation.
