Several months ago I noticed Wikipedia's Ganglia (cluster performance monitoring software) is publicly accessible. Check out db59 (mentioned in the note) amongst the other servers:
http://ganglia.wikimedia.org/latest/?r=hour&cs=&ce=&s=by+name&c=MySQL%2520pmtpa&tab=m&vn= http://ganglia.wikimedia.org/latest/?r=hour&cs=&ce=&...
If you want to see a bunch of other cool public Ganglia instances you can do a search something like:

- zanny 14y agoAny reason why the load on db59 is so high? Are they trying to stress test it?
- JaggedJax 14y agoI couldn't say the reason, but the I/O for db59 [http://ganglia.wikimedia.org/latest/graph_all_periods.php?h=db59.pmtpa.wmnet&m=cpu_report&r=hour&s=by%20name&hc=4&mc=2&st=1355622088&g=network_report&z=large&c=MySQL%20pmtpa http://ganglia.wikimedia.org/latest/graph_all_periods.php?h=...] is much higher than the other servers as well. Also, despite the switch on db59 happening a few days ago, there doesn't seem to be a significant change in overall CPU usage: http://ganglia.wikimedia.org/latest/graph.php?r=month&z=xlarge&h=db59.pmtpa.wmnet&m=cpu_report&s=by+name&mc=2&g=cpu_report&c=MySQL+pmtpa http://ganglia.wikimedia.org/latest/graph.php?r=month&z=...
