Hi Mohit

Have you verified that you are able to complete even a single HTTP request/response transaction to the server on that port? Normally, I would expect to see at least a few complete successfully, but the output below indicates they all failed.

I am getting an error while running httperf test.

I searched on Internet about the same, it says, it's due to limited no. of ports. Adding --hog solved the problem for them. But, here, i am looking for data from a particular port itself 4567. I think --hog doesn't make sense. And it just hangs when I do the same.

Thanks & Regards
