What is the best way to do a log rotation?

I'm using fileop and I wanted log rotation at midnight, but it hasn't been working. Would it be better to move the Schedule to the Output section?

<Extension fileop>
Module xm_fileop

# Check the size of our log file every hour and rotate if it is larger than 1Mb
<Schedule>
Every 1 hour
Exec if (file_size('%LOGFILE%') >= 1M) file_cycle('%LOGFILE%', 500);
</Schedule>

# Rotate our log file every week on sunday at midnight
<Schedule>
When @midnight
Exec file_cycle('%LOGFILE%', 500);
</Schedule>
</Extension>

The above is for rotating nxlog.log.

This should also work for files created with om_file but in that case you will need to also call reopen() from inside the Output block.
