Once again, Geir Høydalsvik and I had the pleasure of hosting a
MySQL mini-seminar in Trondheim. 25+ attendants from at least 7
different companies and a few professors from the computer science
dept. at NTNU showed up on yesterdays event. I recognized
many of these from the first seminar but there were some new
faces as well.
This time, Mark Leith came on a visit from the UK. He gave an
introduction to Performance Schema and ps_helper. ps_helper is a
really nice tool to make sense of the overwhelming amount of data
collected by PS. He also gave a very convincing demo of MySQL
Enterprise Monitor (MEM). More than a few attendants now plan to
give MEM a try in their environment. You can too - there's a 30
day trial, which should be more than enough to decide if you need
it …
Oh yes, 2012 was an incredible year for the MySQL
Community!
That’s why I would like to change the rules this year and I would
like to offer you a new survey for this [Plus]Â reader’s
choice 2012.
Community users, bloggers and events made the whole community
last year, tell us how you used this community?
It will only take 5 minutes of your precious time, votes
will be closed Jan. 31.
Vote for what you used! (with your heart, again…)
