+# FAQ
+Q: I would like to add characters to each line before sending to Logstash?
+A: Logrustash gives you the ability to mutate the message before sending it to Logstash. Just follow [this example](https://github.com/bshuster-repo/logrus-logstash-hook/issues/60#issuecomment-604948272).
+
+Q: Is there a way to maintain the connection when it drops
+A: It's recommended to use [GoAutoSocket](https://github.com/firstrow/goautosocket) for that. See [here](https://github.com/bshuster-repo/logrus-logstash-hook/issues/48#issuecomment-361938249) how it can be done.
