Hi Markus,
you can see the alert using decanter:alert command.
In the case of log, it's a bit special: you receive an alert as soon as
you have a log.level in WARN, and it's stored in the Decanter alerts.
Then, the next log message which is not a WARN will notify you.
I need to improve a bit the mail alerter to only send the first email in
the case of log (it makes sense for metrics, like the ones coming from
the JMX collector).
Regards
JB
