[Che] "event dropped by event filter" should be a debug message
Currently, che
prints by default an "event dropped by event filter" message for each dropped event:
https://git.canopsis.net/canopsis/go-engines/blob/develop/cmd/engine-che/engine.go#L108
On installations which need to drop an important number of events (these installations are common), logs are spammed with thousands of such lines which have no value.
It would be interesting that che
marks this as a DEBUG message instead of an INFO message, and that Go engines provide a way to chose which loglevel to use when starting the engines.
