The server-root/extras/log_anly directory contains the log analysis tool that runs through the Server Manager user interface. This log analyzer analyzes files in common log format only. The HTML document in the log_anly directory that explains the tool’s parameters. The server-root/extras/flex_anlg directory contains the command-line log analyzer for the flexible log file format. However, the Server Manager defaults to using the flexible log file reporting tool, regardless of whether you’ve selected common or flexible log file format.
Use the log analyzer to generate statistics about your default server, such as a summary of activity, most commonly accessed URLs and the server is accessed most frequently. You can run the log analyzer from the Sun Java System Web Server or the command line. The log analyzer cannot generate statistics for virtual servers other than the default server. However, statistics can be viewed for each virtual server as described in Viewing an Access Log File.
You must set the library path before attempting to run the flexanlg command line utility. The settings for various platforms are as follows:
Solaris and Linux:
Before running the log analyzer, you should archive the server logs. For more information about archiving server logs, see Archiving Log Files.
