Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Requests:	Rate of requests for a specific transaction.	Reqs/Sec	An increase or decrease in request rate for a specific transaction can represent a change in the user workload.
Errors:	Percentage of error-filled responses from the web site for a specific transaction.	Percent	Percentage of responses for the transaction that report a 400 or 500 status code.
Data transmitted:	Rate at which the data is transmitted by the web site in response to user requests for a specific transaction.	KB/Sec	A large increase in the data transmission rate can be indicative of an increase in the popularity of a specific transaction. Alternatively, a sudden increase in data rate may also indicate a change in the characteristics of a transaction.
Avg response time:	The average time taken by the web site to respond to requests for a specific transaction, measured in seconds. Only requests for which successful responses are received are considered while computing the average response time.	Secs	An increase in response time is a major cause for user dissatisfaction with e-business sites. By correlating an increase in response time with the other metrics collected by the agent per transaction, an operator can diagnose the reason(s) for the deterioration in performance.
