Zimbabwe Institute of Legal Studies (ZILS) utilizes server logs and log analysis tools to create summary statistics about the use of the Web site.

1. User/client hostname – The hostname (or IP address, if DNS is disabled) of the user/client requesting access.
2. HTTP header, “user-agent” – The user-agent information includes the type of browser used, the browser version, and the operating system it is running on.
3. HTTP header, “referer” – The referer specifies the page from which the user/client accessed the current page.
4. System date – The date and time of the user/client request.
5. Full request – The exact request the user/client made.
6. Status – The status code the server returned to the user/client.
7. Content length – The content length, in bytes, of the document sent to the user/client.
8. Method – The request method used.
9. Universal Resource Identifier (URI) – The location of a resource on the server.
10. Query string of the URI – Anything after the question mark in a URI.
