Alerting by slack,email etc.. when log level error

Elastic Stack Logstash
1

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.
