Trigger rule with error in log

---

Hi,
is it possible to make a rule which reacts on a specific error entry in the pimatic log?

When error "bla blupp" occurs then do some stuff

Hey @ortin,

Check pimatic-logreader. If you set it up to tail pimatic-daemon.log it will probably do what you want and maybe some more

Yes, that was as well my idea, but had a small hope to get it on a simpler way…

@ortin I think it can only be made as simple as you describe if a plugin providing and handling a predicate would be developed. Something might be said to make this core Pimatic functionality, but I’d rather leave it up to @mwittig and @leader21 to decide upon if and when this would be implemented.

Nice idea indeed. I did something similar with the logreader. In parse the daemon log and show the error messages in a text frame. Sure you can grep every error you like and take some action then.
Could be an interesting idea for a plugin imho…

@leader21 Just quickly reviewed the log-reader code and although not very explicitly clear in the plugin description, it allows for Javascript Regex to be used for pattern matching (see snippet below). The difference @OrtiN suggests, is to be able to provide the pattern as part of the predicate instead of the device config. This should be achievable as added functionality in log-reader I think. Don’t mind forking log-reader and having a stab. Before I do, I’d also like to ask @mwittig if he has any thoughts on the topic.

for line in @config.lines
          # for a match.
          matches = new RegExp(line.match).exec(data)
          if matches?
            # If a match occures then emit a "match"-event.
            @emit 'match', line, data, matches
        return
