It would be useful to be able to monitor the following: - Number of threads currently actively serving servlet requests - Total number of requests served - Perhaps break down time/count by endpoint (eg /jmx, /conf, various JSPs) This becomes more important as http-based protocols like webhdfs become more common -- This message is automatically generated by JIRA.

MBeanContainer mBeanContainer = new MBeanContainer(mBeanServer); webServer.getContainer().addEventListener(mBeanContainer); mBeanContainer.start(); 5) Statistics handler will require registration by the look of things i.e StatisticsHandler statisticsHandler = new StatisticsHandler(); webAppContext.addHandler(statisticsHandler); Add metrics for HTTP Server --- Key: HADOOP-8905 URL: https://issues.apache.org/jira/browse/HADOOP-8905 Project: Hadoop Common Issue Type: Improvement Components: metrics Affects Versions: 3.0.0 Reporter: Todd Lipcon Labels: newbie Currently we don't expose any metrics about the HTTP server.
