In my particular case, it's a generalize tool that can be used as a monitor daemon or regression/stress testing. big brother seems to be focused on site monitoring and it costs money. Although JMeter could go that direction in terms of monitoring, that isn't my goal personally. since I'm a developer, I care more about having nightly builds with regression/stress testing. the monitoring from my experience tends to go with custom solutions for a couple of reasons. 1. there might be things you want to monitor which a package like BB won't record. 2. in a complex deployment, there are numerous processes which need to be monitored and those results should generate a report 3. for site that are Application Service Providers, there are Service Level Agreements (SLA's) that have to be met. Often the that means a monitor that understand different levels of warning generated by the application. Say for example your app already sends logs to a specific directory. You would need to write a plugin for BB to monitor and filter the input to the log file. Big brother has lot of good stuff, but there are situations where you will still need to write lots of plugins to cover the level of monitoring required. Of course being open source, some could always write it and contribute it to apache :) peter

So far I've been focusing on Tomcat, since well I use Tomcat. Mike and I have been discussing this for a couple weeks now and I'm also talking to remy about providing support in Tomcat to facilitate this. my plans so far is this. 1. update the new TC5 status servlet to output XML 2. submit the patch once remy likes it. since I need his help to convince the other committers to Ok the patch 3. write a JMeter monitor that is configurable The type of monitor I had in mind is more general. What I want to do is be able to build tomcat + webapps nightly and deploy it. Then an Ant process would kick off to load and regression test the changes. The monitor would ping the server on a set interval to see how it performs. The information provided by the status servlet in TC5 include threads, vm and so on. The design I had in mind was to have a generic parser interface, which the monitor uses. that way it maintains the same level of flexibility and extensibility as other Jmeter components. The regression/stress test plan would have one monitor that records the results. Time permitting after all that is done, I want to write a GUI that allows me to view the performance of the server for the duration of the test. Does that sound similar to what you were thinking of? peter [EMAIL PROTECTED] wrote: Hi, I thought about monitoring our web farm using JMeter. I would write a console to view all unsucessfull polls on one spot and extend the listeners. Of course that console would need to do alerting as well but thats somewhat out of scope... (and quite easy using java) Has anyone done such a thing so far? Is the whole idea nonsense? Is JMeter stable enough to run infinite? Does JMeter work in an environment where I need to test about 1000 targets each minute? any comments welcome --------------------------------- Do you Yahoo!? Yahoo!
