Upgraded Omada Controller and Omada Exporter - Exporter No Longer Runs

[RichieRogers]

Hi, I've just upgraded my Omada Controller to version 5.14.20.9 and exporter to v0.13.0. However, I now get the following error when trying to run the exporter: sudo /bin/omada-exporter --host https://my-omada-server:8043 --username prometheus --password REDACTED --insecure true

panic: runtime error: slice bounds out of range [1:0]

Is there a fix for this?

Thanks, Richie

I'm getting the same errors, though interestingly this only started after the last reboot of my Omada controller yesterday. Before that, it had been working.

Same here.

and here

I'm getting the same error, was driving me nuts until I found this. I did make some changes on the server that was running this docker image, and I thought it was somehow related to that, even if it should not cause this. This is a very useful collector so hopefully, @charlie-haley will have a look at and eventually fix this.

I see the problem, the redirect from / to /cid/login doesn't exist anymore, the login is made here /api/v2/login, the CID can be get later but I don't investigate more...

I forked the repo and added CID param.

I think pass to OpenAPI of Omada is better to avoid futures issues

[RichieRogers]

@mixman68 Great you have a fix. Sadly I have no idea how to compile this into an arm64 deb package I can put onto my Raspberry Pi - any docs on this?

Thanks, Richie

[mixman68]

Hello, it's programmed in golang

so no necessity of .deb, for mine I compile with this command

GOOS=linux GOARCH=arm64 go build -o omada-exporter

after this you get a single executable with all included to run without dependencies

[tukane]

But I can also wait until the fix is included in a new version of the docker file, right?

[charlie-haley]

Hi, thanks for raising this! I should have some time this week to investigate what's exactly happened here, in the meantime I'd recommend not upgrading until a fix has been released

I made a fix by taking ideas from the ha-omada integration. I tested it on 5.14.26.1, don't know if it will break older versions.

For anyone wants to try it out, I pushed a docker image here - https://github.com/blesswinsamuel/omada_exporter/pkgs/container/omada_exporter (ghcr.io/blesswinsamuel/omada_exporter:0.0.3).

confirmed working on 5.14.26.1 - seems like all is working via docker compose.

Confirmed on 5.14.26.1 for me as well

Thanks for the PR @blesswinsamuel! It looks like the OpenAPI integration is working now too, I'll look at building a client from there now which will hopefully avoid issues like this going forward. Thank you everyone for your patience!

[RichieRogers]

Hi, 0.13.1 of the omada exporter works. Thanks for fixing.

Much appreciated, Richie

Hi, Sorry to re-open this one, but any chance of updating the Helm chart to use the new version? I'm migrating over to Kubernetes and this error has popped up again.

Many Thanks, Richie
