If you want to know what's included when using the resetcounters command, just look at the output from 'status detail'. You'll notice after the featurekeys, there is the Counters section with three columns: Reset, Uptime, and Lifetime. When you reset the counters, all the counters in the reset column will zero out, but the Lifetime column will retain its counters - uptime will zero out after a reboot. Similarly, you can go to Monitor -> System Status in an ESA web interface and click the Reset Counters button there. Unfortunately, you cannot reset only a specific counter.
