Yeah those stats look good actually, so the system is not doing a whole lot. So I would not be worried currently.
A consistent %IOWAIT of 3-5% is not too uncommon for an average busy system, which you are nowhere near. And depending on the work load, it could go much higher than that at times and not be too big of an issue as long as it’s not sustained.
You are only using around 25% of your CPU at most, so you have a lot of room there. Once you start getting closer to 70% CPU usage (30% idle) then you should start to pay a bit more attention to it, but chances are your I/O will become an issue first in most cases.
To capture the processlist and InnodDB data, you could run the commands from the command line and output it to a file:
mysql -e “show processlist;” > ~/processlist.log
mysql -e “show engine innodb status \G” > ~/innodb_status.log
