About the PERL ParseLog Script Sample

The client statistics log file for the current version of Windows Media Services can provide very detailed information about the usage of your server. But this detail often makes the information difficult to use. In many cases, all you need is an overview. Windows Media Services logs can be imported by utilities, such as the Analysis tool of Microsoft® Site Server version 3.0. After the log is imported into such a tool, the vast amount of data can be combined in any number of ways to create easy-to-read summaries or full reports. The PERL ParseLog Script Sample demonstrates a very simple approach to building reports, especially if you require regular daily or weekly summaries that always use the same layout.

You can use the script to parse individual log files, or specify a directory from which every log file must be parsed into one report. Summary information includes reception statistics, types of client operating systems, and URL hits sorted in three different ways: by total hits, by unique client hits, and alphabetically.

The following example summary was generated by using this script, and combines data from four different logs:

E:\Logs>parselog e:\logs
Parsing V3.0 log file e:\logs\NetShow.980311000.log
Parsing V3.0 log file e:\logs\NetShow.980312000.log
Parsing V3.0 log file e:\logs\NetShow.980313000.log
Parsing V3.0 log file e:\logs\NetShow.980314000.log
