How can we evaluate the performance of Eucalyptus

How c开发者_如何学Pythonan we evaluate the performance of Eucalyptus. Is there a tool that can collect statistics about the same?

thanks

At least for the S3 Walrus part of Eucalyptus, YCSB (Yahoo! Cloud Serving Benchmark) https://github.com/brianfrankcooper/YCSB has been a very useful tool. You can write custom drivers for S3 operations PUT, GET, DELETE, LIST. Then YCSB enables easy setup and testing that reports latency, errors, and other statistics for a performance analysis.

Some excellent information and resources about EC2 testing in these links:

CPU & Disk: You can run any local benchmark tools, as long as it can run in a virtual environment. - You can enable-disable VT-d between the tests to see the impact.

Network: You can also run network benchmarks using different configurations: - Two instances on the same node - '' on two different nodes - '' on two different clusters - '' with one outside of the cloud

GPU: This is still pretty experimental. You'll have to find recipes on the web (very rare).
