Web resources graphs

Web resource monitor graphs enable you to analyze resources on the web server during a load test run.

Throughput graph

The Throughput graph shows the throughput on the server during each second of the load test run. This metric indicates how the volume of data received from the servers affects performance. Throughput is measured in bytes and represents the amount of data that the Vusers receive from the servers at any given second.

Axis Details
X-axis

Elapsed time since the start of the run.
Y-axis

Throughput of the servers, in bytes.

Tip: Compare with the Transaction graphs to see how throughput affects transaction performance.

Hits per second

The Hits Per Second graph shows the number of HTTP requests made by Vusers to the web server (y-axis) during each second of the load test run (x-axis). This metric helps you evaluate the amount of load that Vusers generate in terms of the number of hits, and shows the workload level on the server.

Axis Details
X-axis

Elapsed time since the start of the run.
Y-axis

Number of hits on the server.

Tip: Compare with the Transaction Response Time graph to see how the number of hits affects transaction performance.

Connections

The Connections graph shows the number of open TCP/IP connections (y-axis) at each point in time of the load test run (x-axis). Depending on the emulated browser type, each Vuser may open several simultaneous connections per web server.

This metric helps indicate when additional connections are needed. For example, if the number of connections reaches a plateau and the transaction response time increases sharply, adding connections could improve performance by reducing the transaction response time.

Axis Details
X-axis

Elapsed time since the start of the run.
Y-axis

Open TCP/IP connections.
