So diagnosis is confirmed. You should investigate why MySQL is taking
that 90%-ish CPU - which is not OK kind of behaviour. 

I can very well guess performing a 'src_host, dst_host' aggregation
with monthly time-bins (sql_history: 1M) and updating content every
minute (sql_refresh_time: 60, sql_dont_try_update set to false) can
lead to some intensive amount of work.

What is the end goal of your deployment?

Cheers,
