Question regarding rotating logs of modsec

Hello dears,

i'm running modsec on latest nginx on centos7. The problem is that i cannot rotate the logs with logrotate.

My logrotate config file for modsec is the following:

> /var/log/modsec_audit.log {
> daily
> rotate 7
> missingok
> compress
> postrotate
> [ ! -f /var/run/nginx.pid ] || kill -USR1 `cat /var/run/nginx.pid`
> endscript
> }
