farquetwrk2img's Issues
Add --max-latency to cut the tail latency
It would be great to add a --max-latency flag [0, 100] that would cut the tail latency at a given value. This can be useful to be able to visualize data with big tail latency while keeping a linear scale.
Support named wrk outputs
wrk2img can currently display multiple lines in the same chart by parsing multiple piped wrk outputs. However, it assumes that the differentiator between the experiments is the number of requests per seconds and uses that to label the line.
However, wrk are more use cases, like comparing performance of different web server frameworks or comparing virtual machines running identical workloads for instance.
This doesn't look like a complicated change to support custom labels, but what would be the preference input for those ?
For instance, we could imagine that the order of the piped outputs matter and add an option that would look like : -l/--labels experimentA,experimentB,experimentC.
