Hi,
I found this blog quite helpful:
https://www.instaclustr.com/deep-diving-into-cassandra-stress-part-1/
on 1, not sure if I understand your question correctly, but I would not
start the stress test process on a Cassandra node which will be under test.
on 3, the tool has already with an option t
Have you read through the docs for stress? You can have it use your own
queries and data model.

The user and password should be in -mode section, for example:

Thank you every one it is working fine.
I was watching jconsole behavior...can tell me where exactly I can
find " *RecentHitRates"
:
*Tuning for Optimal Caching:
Here they have given one example of that *
http://www.datastax.com/docs/0.8/operations/cache_tuning#configuring-key-and-row-caches
It's in the source distribution under tools/stress see the instructions in the
README file and then look at the command line help (bin/stress --help).

Running only one node. I dnt think it is coming for the replication
factor... I will try to sort this out Any other suggestions from your
side is always be helpful..
:) Thank you

UnavailableException is raised server side when there is less than CL nodes UP
when the request starts.
It seems odd to get it in this case because the default replication factor used
by stress test is 1. How many nodes do you have and have you made any changes
to the RF ?
Also check the serv
Have you checked the logs on the nodes to see if there are any
errors?

Hi All,
I was able to run contrib/stress at a very impressive throughput. Single
threaded client was able to pump 2,000 inserts per second with 0.4 ms latency.
Multithreaded client was able to pump 7,000 inserts per second with 7ms latency.
Thank you very much for your help!
Oleg
Look at iostat -x 10 10 when he active par tof your test is running. there
should be something called svc_t - that should be in the 10ms range, and
await should be low.
Will tell you if IO is slow, or if IO is not being issued.
Also, ensure that you ain't swapping with something like "swapon -s"

Oleg,
I'm a novice at this, but for what it's worth I can't imagine you can have a
_sustained_ 1kHz insertion rate on a single machine which also does some
reads. If I'm wrong, I'll be glad to learn that I was. It just doesn't seem
to square with a typical seek time on a hard drive.

Thank you, Tyler!
When I run contrib/stress with a higher thread count, the server does scale to
200 inserts a second with latency of 200ms. At the same time Windows desktop

Try using something higher than -t 1, like -t 100.
