I have to work recently with a Fraud Prevention and Detection solution and needed to check in the enormous configuration which resources are used.
On a daily logrotate I have noticed that one of my monitored applications is doing a
multiline input, but due to a misconfiguration in logstash, the grokparsefailure appears. I just want to leave the message as it is. Therefore logstash provides event dependent configuration capabilities with regular expression comparisons.
In logstash some grokked fields in messages, that suppose to be numeric, flying in with “NaN” (Not a Number). You can convert them with the mutate filter plugin.
