Open source tomcat log viewer

Question

I'm managing several tomcat instances (aprox 30-35) and looking for some console to centralize the logs. I tried php-syslog-ng before (no with tomcat), and found it useful. I would like that these software would have some of these features:

-Syntax highlight according to the severity of the exceptions. -Tree view for stack traces and nested exceptions.

Bonus point:

-Alarm when certain pattern is matched.

Solution 1

you can use splunk : http://www.splunk.com/ in which you can centralize all logs you have, you can then perform crossed search, it's a freeware, a bit heavy but awesome. You can also use lambda probe http://www.lambdaprobe.org/d/index.htm but it's more for global managment, not especifically for logs.

Solution 2

is it possible to change the logging of tomcat to log4j? For log4j there are a lot of logfile viewers:

• LogMX
• http://www.log-viewer.com/net-java-log4j-log-viewer/
• Apache Chainsaw
• Vigilog

They are not all open source but free. Perhaps there is something that helps you.

Solution 3

not exactly a viewer, but does exception sorting and matching:

http://exctractor.sourceforge.net/

a pain to get running, but once set up, can be useful to produce reports/etc.

Solution 4

Have you tried TCLogView?

No, but it doesn't seem to be what I am looking for, also it's not open source.

Splunk is great.. Until you hit the amount of logs that you have to pa for. Then it gets insanely expensive.

Oh, my bad, I didn't know that there was a log limitation. Thanks

Goodness. I'd forgotten about this!

I will add OtrosLogViewer code.google.com/p/otroslogviewer to this list (it's free).

Splunk is fat, while LambdaProbe (now PSI Probe, link below) is lightweight and great. Thx! github.com/psi-probe/psi-probe
