Every time there's an event in Logstash, I ensure that it's logged in a log file. But the problem is that .. the log file keeps growing every day. I need to segregrate logs by the day so I could delete old logs as per my convenience. So, my question is .. Can we have rolling logs for Logstash?

How are you logging the messages, via a file output or a stdout output? In the latter case I think external rotation already works (i.e. use logrotate or a similar tool) but the file output doesn't support external renames. See the issue below.

Keep in mind that the plugin's `path` option supports [sprintf formatted strings](https://www.elastic.co/guide/en/logstash/current/event-dependent-configuration.html#sprintf) so you could use e.g. `/path/to/logfile.%{+YYYY.MM.DD}.log` as the output file's path to have it write events to files named after the `@timestamp` field.
