Hello all, Im a bit confused re alerting, I recently upgraded my elk stack from 7.2 > 8.8
we had bunch of Alerts rules configured to notify a slack channel for example if some index log file has a string "Error"
I dont see these options anywhere in 8.8 alert console, I can only define Log threshold metrics, not actual log content matching.
I am also reading that theres a Watcher piece, which I havent used before, but the Slack Connector isnt available to a watcher (I think I need to use xpack settings to define a connector for watcher)
I basically want KIabana to send a slack alert if some log has a certain string or matches regex conditions, ie if log contains "error"
How can I do this in 8.8 ?
