--- Comment #18 from Sean Pringle <sprin...@wikimedia.org> ---
Regarding monitoring:
We have userstat=ON on the labsdb instances to maintain user_statistics and
client_statistics tables in information_schema. The data is also being logged
on db1044 for time-series reporting, but isn't exposed anywhere yet.
http://www.percona.com/doc/percona-server/5.5/diagnostics/user_stats.html
Unfortunately the user_statistics.concurrent_connections field isn't updated
due to bug. However by logging user_statistics.total_connections we can still
identify spikes.
So far nobody has abused max_user_connections=512, and, as Coren implied
earlier, we can continue to be lenient until forced to do otherwise. Closing.
