LoadRunner monitoring metrics and Chinese explanations

1. Number of Concurrent Users (NCU)

Number of concurrent users – the number of concurrent user connections observed by the system at the specified time.

2. Request Per Second (RPS)

Requests processed per second – indicates the average number of user transaction requests that the server can process per second.

3. Response Time

Response time – The length of time that a transaction request is issued from the customer to the last byte of the processing result.

4. Time to First Byte (TTFB)

The average number of milliseconds that the client received the first byte of the response.

5. Time to last Byte (TTLB)

The average number of milliseconds that the client received the last byte of the response.

6. Think Time

Think Time – The time the user spends on the page before sending the next request.

7. Hits per Second

Number of hits per second

8. Throughput

Throughput – The total amount of data that the customer receives per second in kilobyte.

9. Pages per Second

Pages per second – the number of Web pages that are downloaded from the Web server to the client per second.
