Hey guys,I have a log file like this:

2016-10-17 03:20:37,690 [319299] ERROR Global - Unhandled application error

Which is log4net log type is this.How can I send this file whit filebeat to logstash and how can I pars this?
Already I have ELK analyzing syslog files but I don't know how to pars this kind of files.
any help or suggestion would be appreciated.

Log4net has come up in at least one other thread in the past couple of days and I believe some pointers were given.
