Post Apache Log Rotation

I have an additional apache log that logs everything in addition to the splitlogs that cPanel creates. I place this log file in /etc/apache2/logs which means it shows up as a log that cPanel can rotate here: Home "Service Configuration "Apache Configuration "Log Rotation That's good. But when cPanel rotates the log after it reaches its size threshold, how can I control post rotate functions? I need to restart another process that is reading this custom log file, not just restart Apache. Thanks.
