It is designed for Tomcat 5, but any servlet container +can port the status servlet and use this monitor. There are two primary +tabs for the monitor. The first is the "Health" tab, which will show the +status of one or more servers. The second tab labled "Performance" shows +the performance for one server for the last 1000 samples. The equations +used for the load calculation is included in the Visualizer.</p> +<p>Currently, the primary limitation of the monitor is system memory. A +quick benchmark of memory usage indicates a buffer of 1000 data points for +100 servers would take roughly 10Mb of RAM. On a 1.4Ghz centrino +laptop with 1Gb of ram, the monitor should be able to handle several +hundred servers.</p> +<p>As a general rule, monitoring production systems should take care to +set an appropriate interval. Intervals shorter than 5 seconds are too +aggressive and have a potential of impacting the server. With a buffer of +1000 data points at 5 second intervals, the monitor would check the server +status 12 times a minute or 720 times a hour. This means the buffer shows +the performance history of each machine for the last hour.</p> +</description> +</component> + </section> <section name="14.4 Configuration Elements" anchor="config_elements"> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
