seems to be what i am thinking about and as you said you go further...

i need less flexibility but perhaps a bit easier monitoring interface (our 
operators should be able to see the status of all applications just 
looking over one view [they would do that whenever an email or other 
notification launched by the console tells them there is anything they 
need to take care about])

if you create a monitoring solution for tomcat i might be able to 
customize it (web interface would be perfect for access from everywhere of 
course) to suit exactly my needs easyly and just add some alerters

think we should stay in touch - perhaps i can contribute something to what 
you need

        Thema:  Re: monitoring with jmeter


 
I'm actually working on a jmeter monitor for Tomcat. 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?

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
