I am generating tomcat localhost access logs using the class -

<Valve className="org.apache.catalina.valves.AccessLogValve" fileDateFormat="yyyy-MM-dd.HH:mm" renameOnRotate="true" prefix="localhost_access_log" suffix=".txt" maxDays="<%= @access_log_max_days %>"

Since my node doesn't have sufficient memory for all access logs, I would like to delete the rotated files after 10 min or so. My question is how can we provide a decimal value (or < 1days) value for maxDays construct so that deletion of rotated files occurs more rapidly than once everyday?

Any help will be much appreciated. Thanks in advance!

You can't, the value of maxDays is an integer, with values not greater than 0 meaning no rotation. So the minimal value you can set is 1.

Anyway log files spanning a couple of minutes wouldn't allow you to diagnose almost any problem. Logs take a couple of orders of magnitude less space on disk, than any web application you might deploy, so I don't think rotating logs every day will be a problem.

Edit: A setting of maxDays="1" will still leave you with two log files: the current one and the previous one. If you wish to have just the current one you can disable rotation in Tomcat and use an external utility like logrotate:

<Valve className="org.apache.catalina.valves.AccessLogValve"  
       prefix="localhost_access_log"
       suffix=".txt"
       rotatable="false"
       checkExists="true" />

Logrotate can rotate based on file size, so it should resolve your problem.
