We using some key words to monitoring Logstash error:
- "Beats input: The circuit breaker has detected a slowdown or stall in the pipeline"
- "Beats input: the pipeline is blocked, temporary refusing new connection."
All these were used to be in old Logstash 2.x version and I believe in
5.x seem changed a lot of logs format, will those message and/or key words still exist when same problem/error happen?
