The monitoring community module, available among the nightly builds, allows to track requests flowing into the server and expose basic statistics about the traffic in terms of OGC services being used. Configured in "history" mode it also stores all relevant request details into a database, allowing other tools to perform detailed usage analysis in post processing.This is great, but has some limitations.

Blog ‐ Posted on 12.07.2011 by simone giannecchini

Here you have some basic facts about the library: minimum set of external...
