Inside logstash, what is the official mechanism to know about any critical errors that happen with plugins / inputs / filters during the production run?
For example, I am using
http_poller input and
elastic output. Say, if for some reason the
http_poller is unable to read the input properly from the url or
elastic unable to save the output - is there anyway I can configure logstash to send me alert mails ?
Generating debug / stdout errors to console would not help in backend systems case - right?
