How to get Fortigate interface statistics such as errors/discards

There are two really good ways to pull errors/discards and speed/duplex status on FGT. One method is running the CLI command:

diag hardware deviceinfo nic X – Where X would be the port, for example wan1

Results:

Glass-B # dia hardware deviceinfo nic wan1

On 1500D’s and other large devices the command is a little different. See the bottom.

on 1500D’s it seems the command changes a little bit to : “diag hardware nic port40“— this was the results from a 1500D that is running 10 gig. The output is at the bottom.

Second way

I started doing some research and found that there was a command that would drop you down to a very limited Linux shell. There are a few commands that are support such as “ifconfig”. This blew me away. I have been wondering if there was a command like this for a long time.

Log in through CLI, and run ” fnsysctl <command>” for example “fnsysctl ls”.

So to get the interface stats, I would just run: “fnsysctl ifconfig port16” or whatever port you want to look at.

fnsysctl

And there we go. I have search for some other ways to get this, and have not found anything. If someone finds something better please pass it along.

    Hi!

    Thanks for this useful info.
    I tried it on a FortiOS 4 MR3. It works on this version too.

    Thanks. Just needed to get error counts to prove a P2P circuit wasn’t passing traffic. This works in 5.2.4 and 5.4 RC1

    diagnose netlink interface list {interface}, then look for (errors) txe/rxe, (discards) txd/rxd, etc.

    The command works in this version too!
    Version: FortiWiFi-60D v5.0,build8231,150123 (GA)
