How to limit Tomcat log sizes in SUSE Manager

This document (000020406) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Manager 4.x Server

Situation

Tomcat access logs are not limited by default, and may grow continuously. Eventually, this could fill up the partition.

The log files can be found at /var/log/tomcat, and are named "localhost_access_log.<date in ISO format>.txt" 

Resolution

In the "/etc/tomcat/server.xml" file, look for these lines near the end: 
 <!-- Access log processes all example.
     Documentation at: /docs/config/valve.html
     Note: The pattern used is equivalent to using pattern="common" -->
 <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b"/>

Include a "maxDays" field just before the closing "/>" tag: 
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" maxDays="7" />

In this case, we're limiting the access logs to 7 days. Adjust as needed for your environment.

Restart the services to pick up the change: 
# spacewalk-service restart

Cause

Tomcat access logs use a different log mechanism than the usual system logs. These are not picked up by the system logrotate daemon.
