Can I get results in format suitable for HDR Histogram?

[gunnarmorling]

Hey all, when using the run script (https://hyperfoil.io/docs/howtos/run_scripts/), is there a way to obtain the results (percentile numbers) in the format expected by HDR Histogram (https://hdrhistogram.github.io/HdrHistogram/plotFiles.html)?

[gunnarmorling]

Alternatively, is there any other way to display the percentile distributions from several phases and/or runs in a single diagram?

Hi @gunnarmorling,

With Hyperfoil at the moment you can get the percentile distribution plot for each phase/run by simply creating the report (with the run script is enough to provide the -o ... option). With that report html opened you can browse the phases tab and get something like this:

Unfortunately the report generates one plot per phase, so you don't have all phases in one single plot.

is there a way to obtain the results (percentile numbers) in the format expected by HDR Histogram (https://hdrhistogram.github.io/HdrHistogram/plotFiles.html)?

IIRC this is not exported anywhere but I think it could be a nice, optional, feature to include. Since we are actually using HDR histograms to store percentiles it would be about writing to a file before exiting

Yep, i can add to the already complete answer from @lampajr that you can use the first tab data eg

Which report the response time over time, although it doesn't report the highest 999 percentile and max (which probably would be nice addition, WDYT @lampajr ?) afaik.

[lampajr]

I think both, adding max/p99.999 in that chart and allowing users to download the histogram data would be really nice to add (and shouldn't require too much effort)

[gunnarmorling]

Yeah, having max, 99.99 (and perhaps 99.999) there would be great.

Being able to download the full HDR histogram would be super-useful, then I could merge multiple results into one chart on my end.

With that report html opened you can browse the phases tab and get something like this:

@lampajr, just noticing this chart you shared goes beyond 100% 🤔? It's not something I'm observing locally when creating a report myself, though.

[lampajr]

Yeah I noticed that happening some times but I did not spend too much into it so far.
Most likely the problem is on reporting side (in the html) because I did not see anything "wrong" in the exported metrics, but I will deep dive into that as well!

Logged #588 and #589 for tracking the two feature requests. Thanks a lot for the replies, @lampajr and @franz1981!

Thanks to you for the suggestions @gunnarmorling, really helpful!!
