To configure WSLA, select Options / Settings and enter the
information necessary to download your server's log file:
Options / Settings
Then select File / Download Log. Once the log has been
downloaded and parsed the reports will be displayed in the
tabs.
WSLA requires a log in the format that many web servers
have standardized on. See Web Server Log Files: The Ultimate Clickstream Data Source by Mark Sweiger, for the details.
The C# concepts illustrated by this source code include:
- Querying databases with SQL and OleDb
- Platform Invoke (to use the WinInet API to download the log file via FTP)
- Advanced regular expressions (extracting columnar data from a log entry)
- Saving configuration data (data stored in the Settings dialog is serialized to a config.dat file)
- Decoding IP Addresses using the Dns class
- Using containers (Hashtable, etc.)
