compressing rotated logfiles

compressing rotated logfiles

[Michael P. Soulier]

Hello,

When using multilog or svlogd, it's simple enough to add a processor
of gzip to compress rotated logs. However, it would greatly help our
tools if the rotated, compressed logfile had a .gz file extension.

Can anyone suggest a good way to accomplish this at rotation time?

Thanks,
Mike

Since I assume that you are doing this on linux, I'd suggest that you use 
inotify to watch the log directory and do renames when svlogd has finished 
its post-processing.

Perl API is here:

Well, I was hoping of a way built-in to the tool, but I guess none is
available. The simplest solution would seem to be a simple nightly cron to
perform the compression and thus renaming, since it's not vital that the
rotated file be compressed immediately.
