cleanup.sh logs

We have a cron job set up to cleanup our logs, but I noticed that perflogs isn't being included in the cleanup. Anyone else have this issue? The documentation I found doesn't elaborate which logs are included in the cleanup.sh script.

Here is what I have set up:
@midnight ...../cleanup.sh logs -delete -keep 7 >> /tmp/cleanup.log 2>&1

Yet I have way more than 7 files in my appianlogs/perflogs/*. Like the perf_monitor_db_CH1*.csv...
