Easier Overview of Current Performance Schema Setting

While I prepared for my Hands-On Lab about the Performance Schema at MySQL Connect last year, one of the things that occurred to me was how difficult it was quickly getting an overview of which consumers, instruments, actors, etc. are actually enabled. For the consumers things are made more complicated as the effective setting also depends on parents in the hierarchy. So my thought was: “How difficult can it be to write a stored procedure that outputs a tree of the hierarchies.” Well, simple enough in principle, but trying to be general ended up making it into a lengthy project and as it was a hobby project, it often ended up being put aside for more urgent tasks.

However here around eight months later, it is starting to shape up. While there …

Why I am So Excited About the MySQL Performance Schema

The improved Performance Schema in MySQL 5.6 provides a new way of investigating issues in the database. Many issues that previously required tools such as strace, dtrace, etc. can now be investigated directly from inside MySQL in a platform independent way using standard SQL statements.

The Performance Schema is enabled by default starting from the latest milestone release, 5.6.6. You have instruments which are the things you can measure, and consumers which are those that use the measurements. Not all instruments and consumers are enabled out of the box, however once the plugin is enabled, individual instruments and consumers can be switched on and off dynamically.

As an example take the case mentioned in What’s the innodb main thread really doing? where the main InnoDB thread appears to be stuck in “doing …

What is the MySQL Performance Schema and Why is It Needed?

When you have a non-trivial database installation, you will inevitably sooner or later encounter performance related issues ranging from a query not executing as fast as desirable to complete meltdowns where the database does not respond at all.

Until MySQL 5.5 the tools available to investigate what is going on inside MySQL were somewhat limited. Some of the tools were:

  • The slow and general query logs
  • The status counters available through SHOW [SESSION|GLOBAL] STATUS
  • Storage engine status, e.g. SHOW ENGINE INNODB STATUS
  • The EXPLAIN command to investigate the query plan of a SELECT statement
  • SHOW PROFILE to profile one or more queries
  • The MySQL error log

All of these tools are very useful, but also have their limitations, for example the SHOW STATUS mainly consists of counters that does not provide much insight into what is happening …
