Hello, I've been facing a strange problem. I want to monitor a remote HDD usage using zenoss. I tried creating a monitoring template for the same and added following data source.

Name:     *Used_hdd*
OID:    *.1.3.6.1.2.1.25.2.3.1.6.2*


Testing this data source against my device generates the following output:
*HOST-RESOURCES-MIB::hrStorageUsed.2 = INTEGER: 6776932*

All I want is to view the graph for the above mentioned data souce. I've created a graph definition and added the corresponding data point in it.
Still I'm unable to see any actual data on the graph. (max, avg and cur shows 'nan').

Please help resolving this...

I think the problem is the OID you have put in your performance template.  Have you put .1.3.6.1.2.1.25.2.3.1.6.2 including the last .2??  If you want to graph hrStorageUsed then the OID is .1.3.6.1.2.1.25.2.3.1.6 - the last .2 in your example is the instance.  There will be one instance for each filesystem ie. the data is a table of values and relates to a COMPONENT of the device.  Leave off the trailing .2 and Zenoss should cope with appending the instance automatically.

You need to be slightly careful with the Test button for a data source.  It will run an snmpwalk, which will work for single and multi instance OIDs whereas the actual mechanism that the template uses is more precise.

Cheers,
Jane
