Auditing usage of secured ArcGIS Server Web services

Auditing usage of secured ArcGIS Server Web services: "
ArcGIS Server 10.0 has a nifty new feature that lets GIS administrators audit the usage of secured ArcGIS Web services. If you've enabled security on your GIS server, you'll see an additional tag in your log messages reporting which user is making the request. This can help you track individual user activity on your GIS server.
To enable the logging of user IDs in ArcGIS Server log messages, follow the instructions below.

1. Log into ArcGIS Server Manager.
2. Click GIS Server > Log Files. At this point, you'll see the server log files.
3. Click the Log Properties link.
4. Set the log level to Info:Standard or a higher level of detail. Any subsequent requests made to secured ArcGIS Server Web services will be stored in the logs along with the IDs of the users making the requests.
5. Simulate some user requests by accessing secured services from the Services Directory.
6. Now let's look at the log messages. Although you previously configured the server to log messages of Info:Standard or higher, you also need to configure the log files page to show that level of messages. Go back to Manager's log files page and use the pulldown menus in the Show panel to change the log messages shown to level Info: Standard or higher. If you make a change here, don't forget to click Apply, then Refresh Logs.
7. Click the Manage Columns link and make sure the User box is checked. This is the column that will show you who accessed the service.
   
8. 
   Examine the log files in Manager. For all requests made to a secured ArcGIS Service, the ID of the user making the request is displayed in the User column.
