+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.
