The map service stats provided via Server Manager are useful for identifying trends in service usage. For example, server logs report the total requests per service for a given period/s, which can be quantified and compared over time. However, currently there does not appear to be logs for layer-specific services. So, if a map service has several layers in it, only the "parent" service's stats are reported. This does not allow an understanding of usage for the individual layers in the service.
Adding layer-specific stats into the report logs that Server Manager generates would be much appreciated and very useful.
Thank you,
