IIS Farm View - track traffic on all your web sites.
IIS Farm View lets you look at how each of the web sites on your
server is performing over the month. IIS Farm View keeps
track for each site
- hits
- byte count served
- average response time
- error response rate
For each of these metrics, your sites are ranked from highest to
lowest along with the ranking last month so you can tell if
something significant has happened. The last 12 months of data is
presented. Here is a screen shot.

The top line lets you navigate between the different metric reports.
As well as the system name on the server, you can add a name that
makes sense in your context. The installation and configuration manual
is available as well as some samples.
