Logs message :  
**"message" =\> "Backoff FixedBackOff{interval=0, currentAttempts=10, maxAttempts=9} exhausted "**

I need field like below:  
**"FixedBackOff" =\> {  
"interval"=0,  
"currentAttempts"=10,  
"maxAttempts"=9  
}**

Thanks all

I would do that using dissect and kv filters. Something like [this](https://discuss.elastic.co/t/parsing-firewall-logs-in-logstash/212786/2).
