Thanks!I *think* I have a solution:1. Created a script named make-new-config.sh (see below make-new-config.sh)2. I created a file which will be appended to the dynamically generated one (see logrotate-append.txt below)3. I've added make-new-config.sh to /etc/cron.daily/logrotate on the line directly above /usr/sbin/logrotate /etc/logrotate.conf.What it does? Basically re-generate a new config for logrotate based on what is contained in /var/log/MyHosts/ with more than zero byte size.Any suggestions would be greatly appreciated..vp### make-new-config.sh ####!/bin/sh# This for recordkeeping/troubleshooting, until the next run that is.find /var/log/MyHosts/ -name "*.log" -empty -exec ls -al {} \; > /var/log/MyHosts/Deleted-Empty-Logs# This one to remove unwanted files, presumably from hosts no longer existent?find /var/log/MyHosts/ -name "*.log" -empty -exec rm {} \;# Generate list of valid/current logsfind /var/log/MyHosts/ -name "*.log" -print > /var/log/MyHosts/Latest-Logs-Prepend# Begin creating a new syslog-ng in logrotate.decho "#" > /etc/logrotate.d/syslog-ngecho "# DO NOT EDIT THIS FILE MANUALLY - SEE CRONJOB WHICH CREATED IT INSTEAD" >> /etc/logrotate.d/syslog-ngecho "#" >> /etc/logrotate.d/syslog-ng# Append two files together, making one final /etc/logrotate.d/syslog-ng.# The logrotate-append.txt is shown below.cat /var/log/MyHosts/Latest-Logs-Prepend /etc/syslog-ng/logrotate-append.txt >> /etc/logrotate.d/syslog-ng### logrotate-append.txt ##### DO NOT EDIT THIS FILE - IT IS AUTOMATICALLY CREATED VIA SCRIPT IN CRON## The non-MyHosts nodes will be placed below this line.# Basically, anything that does *NOT* live under /var/log/MyHosts//var/log/messages/var/log/secure/var/log/maillog/var/log/spooler/var/log/boot.log/var/log/cron { missingok weekly rotate 4 create compress copytruncate ifempty# olddir /var/log/MyHosts/Archived-Logs/ sharedscripts postrotate sharedscripts postrotate n/kill -HUP `cat /var/run/syslog-ng.pid 2> /dev/null` 2> /dev/null || true endscript}# END OF FILE> Date: Wed, 7 May 2008 13:00:05 +0100> From: hpsekhon@googlemail.com> To: syslog-ng@lists.balabit.hu> Subject: Re: [syslog-ng] Logrotate Not Rotating All - Need Help Matching Rules> > Quick workaround:> > Write a bash script to generate your logrotate files just before your > logrotate is called by looking at what files exist.
