Sonicwall CPU and Memory monitoring

Votes:

0

How can I configure a sensor in PRTG Traffic Grapher 6.2.1 to monitor CPU and memory usage on a SonicWall TZ190? I'm already monitoring bandwidth on this device, so SNMP is working on both ends. I tried importing the SonicWall MIB via Paessler MIB Importer, and after several "manual edits" to the MIB file I got at least a few OIDs to transfer - but none of them seem to be recognized by the SonicWall when I scan using the imported OID file. Help?

Hello,

PRTG Network Monitor 13.x.5 or later provides an SNMP SonicWALL System Health Sensor out-of-the-box. It can show, for example, CPU and memory usage.

In previous versions, please try the following OIDs with an SNMP Custom Sensor :

  • 1.3.6.1.4.1.8741.1.3.1.4.0 for Memory Usage
  • 1.3.6.1.4.1.8741.1.3.1.3.0 for CPU Usage

You can also use our SNMP Tester to test these OIDs or your oidlib against the Sonicwall.

best regards.

Hi Torsten,

Thanks so much. The CPU OID appears to be working perfectly, but the memory OID does not - though it did pass the OID test in PRTG. Is it meant to be tracking RAM Used, RAM Remaining, Flash Used, Flash Remaining or some other parameter?

Actually, I'd really appreciate getting as many OID definitions for this unit as I can find. Any chance you'd be willing to post a list or direct me to one? All of the posted MIB files for SonicWall that I've managed to find have failed to produce any useful OIDs for PRTG.

Thanks!

I'm afraid these were the only two OIDs I could find to this. Maybe other PRTG and Sonicwall users can help here?

Well, several other sites corroborate that OID as being the proper one for percentage memory used. Mine continuously reports "4" and nothing else.

I did find an exhaustive and informative listing of OIDs for SonicWall and many other vendors here:

http://www.mibdepot.com/cgi-bin/vendor_index.cgi?r=sonicwall

These website is fairly complex hierarchies to wade through - but it is quite useful and explain quite a bit about how OIDs work. I found the site particularly helpful in decoding these numbers.

One very useful OID is for total # of current connections - almost the same as above:

1.3.6.1.4.1.8741.1.3.1.2.0

Thanks all! I hope someone else finds this information helpful.

Cheers,

P
