**Background**

There are many tools to analyze logfiles from servers like Apache HTTP server, but I need one to analyze requests to geospatial services, WMS and WFS

What is special about a request to a OGC service like WMS or WFS? The protocol includes use of geographical request parameters (see e.g. [parameters for WMS GetMap request](http://webhelp.esri.com/arcims/9.3/general/mergedprojects/wms_connect/wms_connector/get_map.htm)), like a bounding box, or geographical filter, i.e. OGC filter. 

Examples of questions I want answered include:

* What is the most common bounding box being requested, boundingbox = (minX,minY,maxX,maxY)
* Do bounding boxes in requests form a "grid", and if so, which grids?

I could import all the log-lines into a spatial database like PostGIS, and then the problem reduces to writing SQL, which is also ok. But it is not trivial to import that many rows on the system I currently have, and then I still need good formulations in SQL.

So, Ideally I'd like a tool that eats log lines and understands OGC WMS, WCS, WFS, CSW etc. 

The problem of Googling this question is the proximity to web log analizers, and WMS = windows media server, and the relative obscurity of the area (geospatial). Maybe the answer you provide is a good google search formulation?

**Question**

Does a tool exist to analyze OGC request logs, to discover things like a recurring spatial pattern?
