Are you a MySQL user? Have you tried 5.0? Did you notice that SHOW STATUS was giving you strange results?
Here’s the skinny: The SHOW STATUS command, which has been in MySQL, well forever, has had a long-standing feature request; to have the ability to report its metrics per-session. That functionality was added in MySQL 5.0, in the form of two new syntaxes: SHOW SESSION STATUS and SHOW GLOBAL STATUS to give the per-session and server-wide statistics, respectively. It’s great, and I’m happy to see it.
The problem comes in because of the default behaviour that was chosen for the basic SHOW STATUS with no SESSION or GLOBAL keyword—that is, the command that every MySQL DBA has been using for years—now defaults to per-session statistics.
Every tool, program, monitoring script, performance graph, etc., that uses SHOW STATUS (which is pretty much all of them) is broken in 5.0. Why? Well, for no reason, in my opinion. There is absolutely no advantage to defaulting to per-session statistics instead of the old standard of global statistics.
If you’re upset about this, add your comment to MySQL Bug #19093 and fight the good fight with me.
