Free PHP software to monitor DB2
SourceForge.net website: DB2 Monitoring Console
If you're looking for a web-based monitoring suite for DB2 9, IBM's brand spanking new upload of DB2 Management Console (DMC) to SourceForge may be worth a look. Peter Kohlmann from IBM mentioned this project at IOD 2007, and it's good to see that DMC is already classified as Production/Stable, and free/open via the Apache 2 license. If you're not the type of person who builds and installs PHP servers for fun, Zend Core for IBM installed rather cleanly for me, allowing me to run DMC without much hassle. Give it a try and see how IBM is approaching the idea of building open-source, web-based monitoring for DB2.
