Joshua McKenzie commented on CASSANDRA-7918:
--------------------------------------------
Given our recent regressions and the upcoming effort for a performance testing
harness, we need to move on this.
Right now we have 1) Benedict's option that has more information but that's
written using gnuplot which people feel strongly against and 2) Ryan's option
that has less information available but is perhaps more immediately /
intuitively digestible and doesn't use gnuplot.
[~enigmacurry]: what are the chances you could integrate the
throughput/latency/gc and tri-graphing approach benedict took into the existing
cstar framework, giving us the best of both worlds? I wouldn't mind seeing the
current format of the #'s from your solution below the graphs.
One other thing - we need to scrape the cassandra.yaml file and dump out the
relevant settings used for the test (or perhaps just all of them at the outset)
as well as snapshotting the specific cassandra-stress command used to generate
the test results for reproduction. A SHA for commit used on the test would also
help, and I think that would give us a solid initial framework to start testing
with and have reproducible tests.
We can pursue future additions onto this later (capturing system info,
/proc/cpuinfo, etc) but there's no point in holding it up to get it to be
perfect for our 1st revision.

> Whilst cstar makes some pretty graphs, they're a little limited and also
> require you to run your tests through it. It would be useful to be able to
> graph results from any stress run easily.
