Ryan McGuire commented on CASSANDRA-7918:
-----------------------------------------

I've made more progress on this, everything from my spec above is now [implemented on my branch|https://github.com/EnigmaCurry/cassandra/tree/7918-stress-graph].


One bug so far is when you don't specify a thread count for reads, it doesn't know how to
parse the multiple iterations at different thread counts (it mashes them all together into
one graph). As long as you specify the thread count your fine.

Here's a test I ran:

{code}
./tools/bin/cassandra-stress write n=1000000 -rate threads=100 -graph file=test7918.html title=test
revision=test1
./tools/bin/cassandra-stress read n=1000000 -rate threads=100 -graph file=test7918.html title=test
revision=test1

./tools/bin/cassandra-stress write n=1000000 -rate threads=100 -graph file=test7918.html title=test
revision=test2
./tools/bin/cassandra-stress read n=1000000 -rate threads=100 -graph file=test7918.html title=test
revision=test2

./tools/bin/cassandra-stress write n=1000000 -rate threads=100 -graph file=test7918.html title=test
revision=test3
./tools/bin/cassandra-stress read n=1000000 -rate threads=100 -graph file=test7918.html title=test
revision=test3
{code} 

And it produced this single 282K html file:

> 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.
