Testing Activities/Events ~~~~~~~~~~~~~~~~~~~~~~~~~ -There were no significant testing activities for this test. - +pidstat is used to collect the process statistics, as such some values such as +%CPU and %USER maybe > 100% as the values are summed across multiple cores. For +more info on pidstat please see: http://linux.die.net/man/1/pidstat. +Known issues: Some reported metrics have the value "unkown". These values are +marked unknown as they are not values retrieved from the external tester +(traffic generator). They were incorrectly derived in a way that made assumptions +about packet sizes, as such they have been deprecated from vsperf and marked as +unknown. They will be resolved in the next release. |
