Package: tomcat6 Severity: wishlist Tags: patch Hi,
Please find attached a patch against current git that adds logfile compression to the existing tomcat6 cron.daily script. We've found compression highly effective on these kinds of logs, reducing the daily logs from 200 GB to 2 GB, a 99% saving. I've enabled it by default, because of the signifcant savings but also because other logs on Debian systems are compressed by default (syslog, Apache to name a few).

From c3d0f9ed145c9b851dc3939c61940614413dd8e8 Mon Sep 17 00:00:00 2001 From: Thijs Kinkhorst <th...@debian.org> Date: Fri, 27 Jul 2012 11:50:22 +0200 Subject: [PATCH] Add gzip compression to cron.daily for logs older than today's one. Compression is very effective on the kind of logging Tomcat produces thus it's enabled by default, also to match the behaviour of e.g. syslog and Apache log compression. Nonetheless the admin can disable it with the LOGFILE_COMPRESS setting in /etc/tomcat6/default. --- debian/defaults.template | 2 ++ debian/tomcat6.cron.daily | 11 ++++++++++- 2 files changed, 12 insertions(+), 1 deletions(-) diff --git a/debian/defaults.template b/debian/defaults.template index 416312c..3ef3280 100644 --- a/debian/defaults.template +++ b/debian/defaults.template @@ -33,6 +33,8 @@ JAVA_OPTS="-Djava.awt.headless=true -Xmx128m -XX:+UseConcMarkSweepGC" # Number of days to keep logfiles in /var/log/tomcat6.
