New snmp memory sensor showing as Response time

Votes:

0

Working with Extreme Black Diamond 8800 systems, I've downloaded, split and imported the mibs with the info I'm looking for (CPU utilization, system memory, free memory, user memory etc).

I've added the SNMP library and the sensor shows up, but its only showing response time, its not graphing the value being returned.

The only channels I can select are downtime (which has nothing) or response time, yet the 'last message' is the number I'm looking to track, graph and alert off of.

How can I fix this sensor?

Hello cco_biamp,
thank you for your post.

This behavior is characteristic of OID's defined as STRING in the MIB Definition. If this is a mistake of the vendor, you can set the "Type" of this OID to "Gauge" in the MIB Importer before deploying the SNMP Library sensors. This should work in most cases as PRTG can ignore the SNMP datatype and read the value in the specified format.

If the value is really a string (and contains text for instance), you can use Regular Expressions to extract the relevant numerical part of the string:

Best Regards,

Thanks for the reply, makes total sense. I'll make the adjustment and re-import the mib
