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 amount of 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 received 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 to the Transactions graphs to see how the 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 to evaluate the amount of load 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 to 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 (x-axis). Depending on the emulated browser type, each Vuser may open several simultaneous connections per web server.
This metric is useful in indicating when additional connections are needed. For example, if the number of connections reaches a plateau, and the transaction response time increases sharply, adding connections would probably cause a dramatic improvement in performance (reduction in the transaction response time).
Axis | Details |
---|---|
X-axis |
Elapsed time since the start of the run. |
Y-axis |
Open TCP/IP connections. |
