Access Logs
Access logs contain information about Internet Transaction Server (ITS) service usage.
This information allows you to check how many requests have been made to a service and helps you to identify illegal requests made to the site by unauthorized users.
Access logs are stored on your hard disk in files called
access.log (or access_*.log in the case of archived files) under:C:\program files\sap\its\2.0\<ITS instance>\logs
There is one entry for each request processed by the AGate component of the ITS and each entry can contain the following information:
