+The mod_jk source distribution contains two perl scripts in the +tools/reports directory which can be used to analyze the mod_jk +logs, save statistical data, and generate report graphs. +

+ +

tomcat_trend.pl log_dir archive_dir

+

+Script for analyzing mod_jk.log data when logging tomcat request data using +the JkRequestLogFormat Apache mod_jk configuration. +Generates statistics for request latency and errors. Archives the generated +data to files for later use in long term trend graphs and reports. +

+ +

tomcat_reports.pl archive_dir reports_dir

+

+Script for generating reports and graphs using statistical data generated +by the tomcat_trend.pl script. + +The following graphs are created: +

    +
  • tomcat_request.png - Long term trend graph of total number of tomcat + requests handled.
    • +
  • tomcat_median.png - Long term overall trend graph of tomcat request + latency median.
    • +
  • tomcat_deviation.png - Long term overall trend graph of tomcat request + mean and standard deviation.
    • +
  • tomcat_error.png - Long term trend graph of requests rejected by tomcat. + Shows requests rejected when tomcat has no request processors available. + Can be an indicator that tomcat is overloaded or having other scaling + problems.
    • +
  • tomcat_client.png - Long term trend graph of requests forward to tomcat + which were aborted by the remote client (browser). You will normally see + some aborted requests. High numbers of these can be an indicator that + tomcat is overloaded or there are requests which have very high latency.
    • +
+

+ +

+A great deal of statistical data is generated but at this time +only long term trend graphs are being created and no reports. +This is only a start. Many more graphs and reports could be +generated from the data. Please consider contributing back any +new reports or graphs you create. Thanks. +

+ +

+These perl scripts depend upon the following perl modules and libraries: +

    +
  • GD 1.8.x graphics library + http://www.boutell.com/gd/
    • +
  • GD 1.4.x perl module
    • +
  • GD Graph perl module
    • +
  • GD TextUtil perl module
    • +
  • StatisticsDescriptive perl module
