Hello, I have installed the ELK Stack and i would like be notify when a log error happen in production. Today i have to go in Kibana et check Log level error but its too much manual.. Is there a way to be notify automatically by slack,email. or other communication type when a log level error happen (maybe not all log level error, i would like to filter some log to alert). I don't know i must do it in Logstash, elasticsearch,.. other way ? I thought about SEntry but it could be like a duplicate in my stack ?! Thank you. ---

Elastic's Watcher product can do this. Elastalert is another option. ---
