Number of probes

Request Mix Accuracy

Note

(Actual % in the Mix - Expected % in the Mix) must be within:

'Main Tx' limit of +/-5.0% for the requests whose expected % in the mix is >= 10.0%

'Minor Tx' limit of +/-1.0% for the requests whose expected % in the mix is < 10.0%

Rate of Non-Critical Failures

There were no non-critical failures in Response Time curve building

Delay between performance status pings during RT Curve (Response-Throughput Curve)
