As a part of monitoring our servers, i decided to take a close look at our web server cluster. As you all know, EPiServer have some counters of it's own to do this. There is not a lot of documentation about theese, but according to the document "EPiServer Operator's Guide" the counter "Data Factory Cache Hit Ratio" should show the percentage of reads delivered from the cache. The value should be close to 100% during heavy load.
The strange part is that our servers shows an avarage of 105%, which seems a bit odd too me :)Isn't the counter working correctly, or is it just our servers?
