Question

FortiAP431F OIDS

I'm setting up PRTG to monitor my network, I'm looking for the OIDs for the FortiAP431F to monitor CPU load and memory util. I saw another post on which a user gave a base OID(1.3.6.1.4.1.12356.101.14.4.4.1.20 for CPU load or 1.3.6.1.4.1.12356.101.14.4.4.1.21 for memory util)  to which I should add on 1.16.(Serial Number in ASCII decimal values). This doesn't work, I was wondering if anyone else has had similar issues and figured out either how to make those work or the correct OIDs? My AP is using os version 7.2.5

          Hi,

           

          Here the answer from one of our FortiAP expert:

          "This link explains how to get the MIB files which contain the OID files for v7.2.5

           

          https://docs.fortinet.com/document/fortigate/7.2.5/administration-guide/608160/mib-files

           

          Download both MIB files and the core one says it includes common files for multiple products. I assume that includes AP."

           

          Regards,

           

          Best Regards

          I have done that already, the MIB does not contain the OID's for the cpu utilization, the memory, the temperature, or the fans of the FortiAP431F

          Hi Nolan

          I didn't work on FortiAP's SNMP before but I'll try to help.

          Is your FortiAP standalone or managed by a FortiGate?

          Did you download the MIBs from the FortiAP431F?

            Hello AEK,

            I appreciate your willingness to help very much. The AP's are managed by FortiGate and  I downloaded FORTINET-CORE-MIB-build1639 and FORTINET-FORTIAP-MIB-build0409

            Hi Nolan

            I have a FortiAP F series in my lab, I'll see if I can extract anything useful for your request.

              Hi Nolan

              Following my tests I couldn't find any related OID on the MIB nor on SNMP walk output.
              So my personal deduction is that there is no such OIDs.

              I'm starting to come to the same conclusion although I'm not giving up yet.

              Following deeper tests I think I've found it (with 99% certitude).

              The two bold lines are CPU and memory usage (resp.) of my first AP (FAP221E). I'm confirming this info with 99.9% certitude according to my tests.

              Hope it helps.

              I'm not familiar with the syntax, how would I convert those lines to an OID? Also what is that screenshot from?

              Hi

              Your AP is managed, then you send the query to FG IP, like this:

              snmpwalk -v2c -c <community-name> <FG-IP> 1.3.6.1.4.1.12356.101.14.4.4.1

              Where do you enter that command? I tried it in PuTTY and it told me no such command exists

              I guess your PRTG is on a Linux host, right? In that case you can install the net-snmp package and run snmpwalk from CLI (I guess it is available for Windows as well).

              Otherwise you can install it and run it from any other host, as long as you allow SNMP queries from the client IP (on FGT's SNMP config).
