It takes about 20 minutes to peak, and another 30 to 45 minutes to come back down to baseline, which is mostly 0.00.

So, you have a time window of ~1h where the system is under load, right?
This is somewhat different to what Ulrich had, but his approach might be
useful for you, too.

Something against running some monitoring and capturing the processes,
process states and load say, every 5 minutes?

Of course, the peaks might correlate to something in the logs - like
cron, logins, logrotates or whatever.
