Web HTTP-HTML: negative values on Analysis

Jump to solution

Hi all, 

we have made a run with Web HTTP-HTML protocol (using websocket communication) and, we had open the Analysis module for results, there're negative metrics, as you can see in the image below,

The same things doesn't happen on Controller,

Can you give me some suggestions about?

Thanks in advance, 

Lorenzo

Hi Lorenzo,

Unfortunately LoadRunner 12.53 is no longer supported...
Also might be that LoadRunner 12.53 is not supported on your Win10 version what you are using (more info at link)

There is a thing what you can try:
1. Go to the LoadRunner installation path and open %LR_PATH%bin\dat\ResponseTimeSummary.def
2. Update the following parts in this file as follows:
[SelectString0]
Dimension=Aminimum (new value to be  Dimension=Transaction Response Time)

[SelectString3]
Dimension=Amaximum (new value to be  Dimension=Transaction Response Time)

3. Save the file (it is recommended to make a backup before the changes)
4. Try to reproduce the issue

Please let me know the results.

Best regards,
Zoli

In add, here's the comparision between Analysis and Controller views: 

negativeMetrics_analysisController.png

In the script there are some think_time() functions, so it maybe the cause of the negative values on Analysis: if I disable think time filter, "Minimum" aren't longer negative. 

How can I explain that? Maybe, the rapresentation of values in the "Summary" table can't go under thousandths metrics?

Thanks for any type of help,

Lorenzo

Hi Zoli, 

we use a Windows 10 Enterprise system and LoadRunner 12.53 version. 

As I said before, in the scripts there're some think_time() functions, but we never see negative results before! 

Thanks, 

Lorenzo

Hi Zoli,

thank you so much for the support. I tried to change values from the file you mentioned and re-made the report from Analysis: I don't see more negative values but only zero: 

MinimumZero.JPG

I ask: can it be due to a minimum that is too small to be represented in the Summary table (with three decimal digits)? 

Thanks,

Lorenzo

Hi Lorenzo,

IMO yes, it can be zero
