measures performance of an object storage platform. to do so, compute instances act as test agents performing io operations and capturing associated performance metrics. testing supports the runtime parameters described below. in addition to local concurrency using the 'workers' parameters, higher load may be tested using parallel testing from groups of 2 or more compute instances all performing io against the same storage platform/container. testing does not utilize local storage io. to accomplish this, download tests are written directly to /dev/null and upload tests from repeat random byte strings generated by dd if=/dev/urandom and maintained in memory. the reason for this is to avoid interference from network based block storage where io capacity may be limited or might even share the same network link. result metrics bw mean aggregate (for all workers) bandwidth (bytes/sec) bw_median median aggregate bandwidth (bytes/sec) bw_mbs mean aggregate bandwidth (mb/sec) bw_mbs_median median aggregate bandwidth (mb/sec) bw_rstdev relative standard deviation (sample) of aggregate bandwidth metrics bw_rstdevp relative standard deviation (population) of aggregate bandwidth metrics bw_stdev standard deviation (sample) of aggregate bandwidth metrics bw_stdevp standard deviation (population) of aggregate bandwidth metrics ops total number of test operations (segmented op counted as 1) ops_failed failed test operations ops_failed_ratio ratio of failed to total operations as a percentage ops_pull pull test operations ops_push push test operations ops_secure number of secure/https test operations ops_size mean size (bytes) of test operations ops_size_median median size (bytes) of test operations ops_size_mb mean size (megabytes) of test operations ops_size_mb_median median size (megabytes) of test operations ops_success successful test operations ops_success_ratio ratio of success
