Hi, Thanks, that’s useful to know. Rds, Mike
-----Original Message----- From: logback-user [mailto:[email protected]] On Behalf Of Adam Gent Sent: 02 March 2016 14:52 To: logback users list Subject: Re: [logback-user] logback and flume For what its worth (hopefully relevant, helpful and not too tangental) I found it more reliable to publish to a RabbitMQ cluster (logback/log4j plugin) and then have Flume consume from Rabbit which then pushes to Elastic Search. I really wish I could give high praise to flume but it really has given us a ton of headaches. It will run out of memory, drop messages, and silently fail. This maybe because we just don't have it configured correctly and/or just that the Elastic Search plugin for flume is not mature enough. The Elastic Search flume plugin for sure has some bugs when it sees JSON like data in a message body it tries to parse it even if its not JSON. Since flume was only used to read message from RabbitMQ and then push messages to Elastic we have a replacement in the works written in Rust but is not production ready. RabbitMQ is actually pretty darn good logging aggregation system even if that is not what it is designed for.
