there's actually a good reason for it. It's not so much a design flaw as it is poor documentation.
In order to not repeat, the graph could grow infinitely large, especially for long running tests. That would quickly chew up a ton of memory and make JMeter crash. It was never meant to be a normal time series graph and was only meant to give a rough idea of what's going on. I'll give you an example. If I have a long running test that goes for 3 days, how wide would the graph be? I've run tests for 1 week in the past with jmeter. What you're looking for is a different kind of graph, which currently doesn't exist in jmeter. I thought about writing one in the past, but never got around to it. I haven't been active with jmeter since 2007. If you want a real time series graph, i would suggest implementing it yourself. You can look at the existing listeners to see how they work. In my mind, the bug is in the documentation, since it never really explains the purpose of the graph and the rationale behind it. peter On Wed, May 13, 2009 at 8:03 PM, drubix <[email protected]> wrote: > > Even if it's not a bug, it's definitely a design flaw.
