Updates to metrics fetching intervals are not applied

[0xgouda]

Describe the bug
If using individual metrics updates to fetching intervals done via the webui or in the yaml files are never applied, in contrast, if using preset updates to fetching intervals in the preset definition are directly applied after a new metrics refresh.

To Reproduce
Steps to reproduce the behavior:

1. run pgwatch with individual metric (e.g., wal: 10)
2. Let it run for a while
3. update metric fetching interval to 60
4. wait and observe that it will never be applied
5. run pgwatch with preset (e.g., basic)
6. Let it run for a while
7. update fetching intervals in the preset definition
8. Observe that it will get applied directly after sources + metrics refresh

Expected behavior
Updates to individual metrics fetching intervals must be applied.

Hi @0xgouda
I’ve started investigating the config refresh logic.

From initial analysis, it seems that interval updates for individual metrics are persisted but not reapplied to the running metric schedulers, unlike preset-based metrics which correctly trigger a refresh.

I’d like to work on fixing this by aligning individual metric refresh behavior with the preset reload logic.
Will share findings or a PR soon. Please let me know if this approach sounds good.

Sorry, I was already on it, please ask for assignment before starting work to save your time.

Also you might want to join #pgwatch channel in postgresql slack communication there will be much faster.

Thanks for the clarification @0xgouda, and sorry about that -noted for next time.

I’ll make sure to ask for assignment before starting work going forward.
I’ll also join the #pgwatch Slack channel for faster communication.

Thanks!
