Hi David,
The problem for me is that I'm searching for a solution that can works for development (though less of a priority cause you can switch config between dev and cf) and for viewing logs via "cf logs" in addition to a log aggregator. I had hoped that /u2028 would work for viewing logs via "cf logs" but it doesn't in bash. I'd need to write a plugin or something for cf logs and train all my users to use it. Certainly possible but I'm not that desperate yet. :)

If \u2028 doesn't work in your environment; use something else; eg NEWLINE

Hi Jim,
So, to be clear what we're basically doing is using unicode newline character to fool loggregator (which is looking for \n) into thinking that it isn't a new log event right? Does \u2028 work as a new line character when tailing logs in the CLI? Anyone tried this unicode new line character in various consoles? IDE, xterm, etc? I'm wondering if developers will need to have different config for development.

With the Java Logback library you can do this by adding "%replace(%xException){'\n','\u2028'}%nopex" to your logging config[1] , and then use the following logstash conf.[2] Replace the unicode newline character \u2028 with \n, which Kibana will display as a new line.

to replace the token with a regular newline again so it displays "properly" in Kibana.

Hi Jim, Thank you for sharing it with us. Two things - for Java, we are working toward defining an enhanced metric format that will support transport of Multi Lines. Could you please share a link to track status of this work? So there are "first class citizen"(Java) and others (Ruby, Python etc)? Is it so rare case that we should use workarounds? The second is this workaround that David Laing suggested for Logstash. Think you could use it for Splunk?
