🔖 Feature description

Hey, I have a dashboard (rspamd) that will contentiously increase counter of rejected mails. To be able to monitor it, I do create following JSON Monitor:

http://mailserver:11334/stat
JSON-Abfrage:actions.reject
Expected Value:2

I will be notified when rejected mails amount will be increased by any value, but only once. Then I need to update value in UK.

✔️ Solution

It would be nice to have an option to monitor changes, e.g. value was reported as n+1, then alarm was triggered and next time it becomes "expected value", monitor goes green and only send notification if value changes again.

It shall be expected that value can goes back to n-1 or 0 in some time.

❓ Alternatives

I need to update monitor by my hands after values was changed.

I think such a feature sounds more like the push monitor.

It would be very hard for us to provide a good UX for what you are asking without sacrificing simplicity.

As I sad, I do pull JSON monitoring and could not find any way how to monitor changes in JSON answer without any middle service.

Just 💡 after I wrote this request: I can create a notification trigger to home assistant and already home assistant can call UK api and change particular monitor value to the new one...

But I could not find REST API description for Monitor update, should I use Socket for this?

If you are willing to use our internal API and deal with the according breakage once that happens yes.
It is somewhat documented on the wiki.

Feel free to contribute engineering resources if you want to make this more solid.
