OurSQL Episode 49: Stalking MySQL

Reminder: Due to busy summer conference schedules, we are going to be publishing the podcast every other week.

This week we talk about a monitoring plugin from PalominoDB that uses caching (like the cacti templates) and allow for arbitrary calculations of thresholds based on status and system variables, and items from the PROCESSLIST.

Nagios
pnp4nagios - from the site, "PNP is an addon for the Nagios Network Monitoring System. PNP provides easy to use, easy to configure RRDTools based performance charts feeded by the performance data output of the Nagios Plugins."

OurSQL Episode 31: The MySQL Ecosystem

This week, Sarah's off, and Sheeri interviews Brian Aker of Data Differential, mostly about the MySQL Ecosystem.

Among the topics discussed are whether the MySQL Ecosystem has peaked yet, the exciting talks coming up at the O'Reilly MySQL Conference including the state of the community keynote, and when the Drizzle software is going GA.

Some parts of the MySQL Ecosystem that were mentioned:
phpmyadmin
Percona Server
Percona free InnoDB hot backup tool

OurSQL Episode 29: Subpar Subqueries

This week, we discuss how & why to optimize mysql subqueries.

OpenDatabaseCamp, also known as OpenSQLCamp - http://planet.mysql.com/entry/?id=26922 will be held in Sardinia, Italy on May 6-7-8, 2011.
Google Group for OurSQLCamp: http://groups.google.com/group/opensqlcamp

Manual chapter for subqueries in MySQL - http://dev.mysql.com/doc/refman/5.1/en/subqueries.html

The WorkLog entries for “subquery” http://forge.mysql.com/worklog/search.php?t=tds&k=subquery&v=0&s=0&p=0
All are low/medium priority. out of 29 worklog items, 9 are complete, almost all are scheduled for 6.0. Of the remaining 20, 1 is in progress, 4 are in the in-design stage, another 4 are simply “assigned”, 11 are unassigned. None are on hold or cancelled, so that’s good.

Trouble with Percona blog at mysqlperformanceblog.com

In the past few days it has come to my attention that some people are having problems with Percona's blog at http://www.mysqlperformanceblog.com. I was told that trackbacks seem to be broken and some comments were not showing up.

Anyone else having any problems with what looks like censorship? [edit: trackbacks were a technical error, Dave's comment was trapped in a spam trap. Still looking for people to comment whether or not they're seeing a similar issue, as it's important for people to check to see if their comments are showing up.]
