Response Times Over Time since 0.2.1
From all the tutorials floating around in the net on how to get response times graphs from JMeter log files it is clear that this feature is missing to a lot of JMeter users. Well, this is history now, as the Response Times Over Time Listener is now part of the plugin package!
This graph will display for each sampler the average response time in milliseconds. And here is how it looks like:
Hi, I don't know if this is caused by the grouping functionality (0.2.2_RC2), but when loading a jtl file in this graph the Y-axis has values 0 till 100000, while the highest peak in the graph is only 38000. Is it possible to set definitions for the min and max value for the Y-axis? I also tried setting the jmeterPlugin.optimizeYAxis to false. This helped a little, but still a lot of white space is between the hightest peak and maximum value of the Y-axis. If it is unclear what I mean, please let me know and I will e-mail you an example. Kind Regards, Sander
Hi sander,
This is a known problem, I will fix it in the future. Basically, the max chosen by the chart is wrong for average values. If you have a point which is 2=avg(1,2,3), the max should be 2 but as of now it is 3.

Hi Sander,
The last version (0.3.0) should improve this.
Hi Stephane, I downloaded 0.3.0 and it seems to have improved a lot. However, I noticed that whenever a transaction exceeds a certain value (Looks like it's 50000ms. I see it when a single transaction has for example 69000ms), the Y-axis has values till 100000. Can you confirm this behaviour? It's not annoying or something, but it got my attention. Sander
Hi,
Yes this is the current behavior. you can have maximized charts by disabling the optimizeYAxis.
Hi, this may sound a bit silly, but are you using moving averages to plot the graph like you would in excel using the moving average option in the analysis pak in excel
Hi, no it is standard average, a point at time = t is the average of all values at that time. Note we group all values t+granulation to t.
Hello, how is the "Aggregated display, all Samplers combined" calculated? As average for all samples? Thanks.
Hi, Yes, it is average for all samples.
Hi, could you explain why when I run a test, in Jmeters aggregate report I get a MAX value of 8.5 seconds, but this graph (Response Times over Time) only shows a MAX value of 7 second?
Is this correct or do I interpret the graph functionality incorrectly?
TIA
This graph shows average response times per second. So you see maximum of per-second averages.
I'm using jmeter 2.5 with the JmeterPlugins? 0.4.2 and this graph just seems to be wrong to me. On the Summary Report I have a transaction that has an average of 142 ms with a max of 817 ms. But the Response Times Over Time graph shows it hovering around 4000 ms. Do you know why this would be?
Thanks, Chris
check the percentile or distribution chart so you can check your values

I think that Settings must have Aggregated display, grouping(tn in jtl file) Sampler combined.
