This morning I was reviewing some of my apache performance trend charts and noticed that I've had several occasions where the Apache CPULoad measurement recorded in Hobbit is over 100%. Has anyone else seen this?
I'm using the tag apache=http://webserver:port/server-status?auto to get the data, and the apache2 graph def to display it.

Hobbit just grabs the data that Apache reports and stuffs it into the RRD.
The Apache docs at http://httpd.apache.org/docs/2.0/mod/mod_status.html claims that it is "The current percentage CPU used by each worker and in total by Apache" which sounds as if it should not be possible for it to go above 100% (hmm ... guess it depends on how they handle multi-processer systems).
