Innotop (http://code.google.com/p/innotop/) has to be one of the best InnoDB monitoring I’ve become accustomed to while wearing a DBA hat. It allows you to get everything from what queries are currently running to the number of queries per second to monitoring deadlocks to even seeing the InnoDB I/O information. One of these days I plan on going fairly in-depth with the intricacies of monitoring with innotop, but as for today all you get is an installation guide with a quick breakdown of various errors and fixes during the install process.

Installation

$ curl -O http://innotop.googlecode.com/files/innotop-1.8.1.tar.gz
$ tar -zxvf innotop-1.8.1.tar.gz
$ cd innotop-1.8.1
$ perl Makefile.PL
$ make
$ make test
$ make install
