Re: [ovirt-users] Log4j hostname

You're showing a logstash parsing, extracted from a message formatted using syslog. All the magic should be in the pattern line (log4j.appender.myappender.layout.ConversionPattern=[%c] %m%). And logstash failed to parse the line anyway (see the _grokparsefailure). Did you try to send native log4j event to logstash, using custom appenders like my own : https://github.com/fbacchella/ZMQAppender > Le 11 mai 2016 à 08:20, Dominique Taffin <dominique.taffin(a)1und1.de&gt; a écrit : > > Hello! > > Thank you for your reply.
