Hi,
I'm sure it's possible to get nginx stats, but you'll have to refer to nginx documentation to figure out how to do this. I don't know why you'd want to do this, though. Throughput is the number of replies per second received by a client. The average throughput is reported at the end of the benchmark as "Reply rate". Latency is the amount of time that passes between a client issuing a request and receiving the reply for that request. The average latency is reported at the end of the benchmark as "Reply time". You can also see these number per client in the log files in the client container's /output directory. You can change the number of clients at runtime if you are willing to modify the source code of the benchmark to do what you want. There are no actual videos, they are just simulated from logs that define the access pattern. Again, you can change the logs to create a different access pattern and thus change the request rate, if you are willing to modify the source code to do this.

Hi all, I'm trying to run Media Streaming benchmark from cloudsuite 3.0 on an ARM Juno platform. I have three questions: - Is it possible to get runtime statistics from the server side (nginx) instead of client side (httperf)? how are the throughput and qos metric (maybe latency?) defined? - One of httperf webpages<http://www.labs.hpe.com/research/linux/httperf/wisp98/html/doc004.html> defines throughput as number of replies received to the time taken. so from the client-side statistics obtained throughput is the request-rate, right? - Is it possible to change the number of clients on httperf at runtime? or the bitrate of the video? this should allow us to vary the throughput (request rate), right? Regarding the qos metric, how do we capture this? I have not found any specific documentation for this. Any help will be appreciated.
