What are some ways to store Tomcat 6 stdout and stderr logs to external server?

  • 772

Due to compliance issues, there is a need to store all tomcat logs for at least 6 months on a central server.

Is there a way to send the logs to rsyslog server or any other mechanism that will accomplish the task. I tried changing CATALINA_OUT to /var/log/syslog, and it does record it in the file however rsyslog-mysql does not pick it up.

Short of sending the logs to a remote host, what are some ways to move the logs automatically besides using rsync, cron, scp

tomcat linux logging

  1. Here is an interesting thread about your question. If this really leads to a solution is not sure. A working approach is to output to stdout and pipe that to logger - but this is not a "clean" solution.

  2. Check out Splunk

    http://www.splunk.com

    Here is some information about how you can set archive policies:

    I'm not sure what kind of compliance you are trying to meet but Splunk has some great plugins - ex:

    SEC http://www.splunk.com/view/sec-compliance/SP-CAAAGMQ

    HIPPA http://www.splunk.com/view/hipaa-compliance/SP-CAAAGG6

    PCI http://www.splunk.com/view/SP-CAAAFHB

  3. Splunk!? That thing is so expensive. It's a good Thing, but an expensive one.

    What you might get more of a kick out of is something like Logstash, or Graylog2

    Logstash will pretty much do exactly what you want. It has an agent that can tail logfiles.

    I wonder though.. What would happen if you pointed the catalina.out log entry at a FIFO pipe, then piped that through logger (which writes to syslog)
