PRTG in Fortigate

Hello,
first of all please check if the SNMP Settings (Version, Community String, port, eventual authentication, etc.) are correct. Then please also check if PRTG (or the PC on which PRTG is installed) is allowed to send SNMP Requests to the device in case (this usually has to be allowed on Firwalls). You can also use our SNMP Tester to test the SNMP-Functionality on the target device(s). For example reading the Device Uptime should definitely be possible.

Best Regards.

Hi, Thanks for your reply... I did some tests and I have some news about the question.

I downloaded and installed the Fortigate MIB that i found in http://www.oidview.com/mibs/12356/md-12356-1.html. Then I use the SNMP Tester but I obtain the following error: "Value: Error converting OID (SNMP error # -2007)".

On fortiGate I've configured the SNMP v.1/v2c... Now the error is: "No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)"

How I can I configure the port on PRTG Network Monitor?

Thanks again.

The SNMP Port can be set on the "Settings"-tab of the device in PRTG under "SNMP Credentials".

OK. I've resolved the problem. Thanks a lot.

i have a different problem, i am able to load the MIB into PRTG but the sensor but the metric comes out with an # and you cant tell what format the value is in also the value never varies. when i importe the MIB it had like 500+ sensors to choose from

It should be possible to change the unit in the Channel Settings of the sensor. However, for detailed explanations on the counters themselves, please consult with Fortinet.

Hello,

I have same problem as Marco, could anyone help me with a step by step tuto to add a captor on a fortigate unit to manage bandwith please ?

Thanks for your help !

Where exactly are you stuck? It's actually just enabling SNMP on the fortigate and then setup SNMP traffic sensors that point to the Fortigate? :) It'll show all interfaces and you can select the ones PRTG should monitor.

@marco, can you share what was the issue that solved your issue? have been already searching for days on the exact same thing. I have a probe inside of the mgmt network. so direct connection to the mgmt interface where I have enabled snap on. also have already configured several times again and again the snap settings and community name

always I receive the message No response

Does the SNMP uptime sensor work?

OK rebooting made me already activate the SNMP it seems. I have already nice sensors thanks to the fortunate MIB's but when using the SNMP traffic he loads directly. but then it seems to hang with the message "Preparing sensor settings..." I really want to have Interface monitoring from the Vdom vlan's on the LACP's.

does anybody have the same issue?

ow the version used from fortigate is the 5.4

Is it possible that the MIB file is too large, i.e. too many counters? When you finish importing the MIBs, you get a statistic window with the found counters. Can you post that?

If your configuration are right and you can't restart your fortigate you can just do this command : diag test application snmpd 44

SNMP Daemon Test Usage

1: display daemon pid

2: display snmp statistics

3: clear snmp statistics

4: generate test trap (oid: 999)

99: restart daemon

and after this :

diag test application snmpd 99

Hello,

I have successful to import MIB.

Done restart PRTG by restart Core and Probe services

Success get return value by SNMP Tester

However there are nothing be discover by "Auto Discovery".

That means I need to manually add new senor by individual OID?

Thanks!

Please post the result of the MIB Importer after loading the MIB file. Thanks!
