Metrics doesn't update and generates a console error

[gen-angry]

Steps to reproduce

Go to Server -> Metrics.

Expected behavior

Metrics are up to date, no console errors.

Actual behavior

I get a 404 error for /actuator/metrics/komga.sidecars. Metrics do not update unless I take the docker container down then bring it back up.

Logs

Going to the metrics page generates a 404 on /actuator/metrics/komga.sidecars in the console.

Server logs generate:

2024-08-04T01:38:03.436-04:00  WARN 1 --- [http-nio-25600-exec-1] o.s.web.servlet.PageNotFound             : No mapping for GET /settings/metrics

for each visit.

Going to /actuator/metrics generates this JSON:

do you even have sidecars?

do you even have sidecars?

I'm sorry, I don't know what that is. I installed it using the docker compose from this page. If it's a dependency, shouldn't it be included?

[gotson]

it's unclear what your problem is, is it only errors in the javascript console, or some errors in the webpage ?

Yes, sorry. The 404 error for /actuator/metrics/komga.sidecars is in the javascript console in browser and the metrics page is not updated. The only time the page is updated is when I restart the docker container but then it's stuck again with the 'updated info'.

The page itself is fine, just with outdated data that is never updated.

[gotson]

and the metrics page is not updated.

what does that mean ? can you clarify ?

This page is never changed no matter how many files I delete or add until I restart the docker container. If I do that, it will update then stay the same again even if I delete or add files.
