Alert on log message

[jkaberg]

Describe the feature you would like to see

I'd love to see an alert mechanism based on when certain criteria are met, like for instance regex matching against log messages (something like r'\b(error|warning)\b') where when this is met fire an customizable message to device Xy. I think this should be either per Dozzle instance, or per (docker compose) stack (eg applies to all containers in the stack) or on an container level (the one container).

It would in the same sense also be cool to get notification when container is not running for whatever reason.

My current stack includes Gotify, however any such feature should ideally support several notification providers. I know of Apprise, perhaps there is something similar in go? In addition to an message it would be cool if Dozzle also could flag the log line and container in the UI for easy lookup

Oh an btw, love the approach you have on Dozzle. Keep up the good work! <3

This question has been raised several times. The issue isn't with the alerting; it's about processing all the logs in the background. Dozzle does not process any logs in the background. Most users wouldn't want this, as it would significantly increase CPU usage. I can't think of a compromise that would allow Dozzle to remain nimble and lightweight while still processing all logs across all hosts for alerting.

@amir20 I think it might need some clarification on this point in the docs, wdyt?

You can achieve the same alerting functionality with Prometheus, Alert Manager, and cAdvisor, a lightweight solution that's very easy to deploy and configure via simple YAML files.

I am working on this feature actually. So more on this later when I have time to update the other discussion.

I see some alert functionality which is released which is awesome. Will we be seeing any native apprise functionality in the future?

Dozzle supports webhooks that you can send to your choice of API. Including apprise.

Dozzle Cloud is a hosted solution that abstracts the complexity away.
