Summary - New activity counters added to NdbApi, and exposed in MySQLD via SHOW STATUS command - Useful for : - query debugging and optimisation - understanding performance - server monitoring - Pushed to 7.0.22, 7.1.11. Patches : http://lists.mysql.com/commits/130471 http://lists.mysql.com/commits/130841 See attached text file for details.
I'll do this in two parts: Part I: Add basic documentation for all the new status variables; add section to Cluster Management with overview of counters and corresponding status vars; some basic SHOW/SELECT statements. Part II: A tutorial with more detailed examples. (Possibly repurpose this as a DevZone article if Frazer is agreeable?)
