PRTG in Fortigate

I'd like to configure PRTG Monitoring on Fortigate. I configure the SNMP traffic on the wan interface but i obtain the following error:

"No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)"

I read some forum (like http://kb.paessler.com/knowledgebase/en/topic/17773-how-to-configure-fortigate-snmp-traffic-in-prtg) and I find that I have to download the MIB from fortinet web page and then to install it on fortinet. At the end I have to install MIB Importer. Is it correct?

There is a best way?

Thanks. Marco

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".

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.

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

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
