SUMMARY

STEPS TO REPRODUCE

Create a virtual router. Wait for dnsmasq.log to exceed 10M and be rotated two or more times. The rotated log files are not compressed.

Contained within cloud-scripts.tgz on systemvm.iso, the file etc/logrotate.d/dnsmasq specifies the delaycompress option. Presumably this means the intention was for the logs to be compressed, but as noted in the manpage for logrotate, the delaycompress option "only has effect when used in combination with compress".

EXPECTED RESULTS

I expected logs dnsmasq.log.2 and higher to be compressed as per this hypothetical output.

$ ls /var/log/dnsmasq.log*
/var/log/dnsmasq.log
/var/log/dnsmasq.log.1
/var/log/dnsmasq.log.2.gz
/var/log/dnsmasq.log.3.gz

ACTUAL RESULTS

None of the log files are compressed.

$ ls /var/log/dnsmasq.log*
/var/log/dnsmasq.log
/var/log/dnsmasq.log.1
/var/log/dnsmasq.log.2
/var/log/dnsmasq.log.3

To fix, the "compress" option should be added to /etc/logrotate.d/dnsmasq
