Can someone please point me to the doc and info about the Performance monitor and it's API?
Thanks,

Gerry,

To learn more about how to use the performance monitor you also have this great post.

If you want to develop your own LifeTime plugin check: If you start using the LifeTime monitoring API, don't forget that for performance reasons, it only stores performance data from the two previous days. So you should take care to save what you need on your side. Check the Geo-Performance plugin to see how it can be done.
