Varnish Newbie Logging Question

[Jorge Díaz]

Hello,

We are using in production Varnish 2.1.2 in Solaris 10 machine.

To dump logs we are using "varnishncsa" and "rotatelogs" program from our
Apache Web server instalation:

*varnishncsa -P ${HOME}/varnish/conf/varnishncsa.pid
|${HOME}/srv_httpd/bin/rotatelogs -l
${HOME}/varnish/logs/acc_%Y%m%d_%H%M%S.log 3600*

varnishncsa is started at same time that varnishd as Solaris service.

We rotate logs once every hour (we have a lot of requests) outside we have a
machine with Apache+Awstat with a crontab script that retrieves logs with
SFTP.
