[ENHANCEMENT] - Frigate Icon

[shadow7412]

Can we add https://frigate.video to the list of detected applications? It's the only one I have running 24/7.

@shadow7412 Can you get me the result of nvidia-smi while Frigate is actively using your GPU? I need to see what process it runs to trigger the app detection.

Hmm. You might not have a great deal to work with here...

[shadow7412]

(both of those are frigate, by the way)

[b3rs3rk]

You're right about that. I have a second method of detection though but is an extra step. Again, while Frigate is using your GPU, take the PID from nvidia-smi for each process and execute the following for each process and paste it to me:

cat /proc/<pid>/cmdline

Poking around in there for anything useful, I did come across /proc/44160/cwd which contains a folder called frigate... but that's the best I could see. Perhaps you know of something in there that might be more useful (like, getting the parent pid?)

[shadow7412]

Ok.

So, the following steps seem to work.

1. nvidia-smi (to get the pid)
2. cat /proc/53892/task/53892/status | grep PPid (where 53892 is the pid found in the previous step. Note it's present twice in this command)
3. cat /proc/91204/cmdline to get the command line of the parent process, which is python3-u-mfrigate.

@shadow7412 Does the plugin detect Frigate now?

[shadow7412]

Looks like there's been a regression :(

Are there any logs I could attach to help you diagnose what's wrong? (There's no related javascript errors coming up in the console)

[b3rs3rk]

@shadow7412 Can you update your plugin and test again? Thanks.

[shadow7412]

I just updated - the plugin is no longer broken, but I'm not seeing frigate in the active apps.

[shadow7412]

Here is a screenshot of me going through the process I outlined in the ticket above, in case that helps you in any way.

[b3rs3rk]

Hmm, I'll have to look at my code again, but my initial impression is that it should be working with the parent process detection I added.

[shadow7412]

I had a poke around - and have raised a PR with a change I think will do the trick.

[shadow7412]

Let me know when I can test the release.

[b3rs3rk]

@shadow7412 You should be able to update and try now

[shadow7412]

Hmm. Still no dice...

[shadow7412]

For what it's worth, upgrading unraid to 6.11.5 didn't seem to make an impact.
