Average Transaction Response Time Graph

This graph displays the average time taken to perform transactions during each second of the load test scenario run.

Purpose

If you have defined acceptable minimum and maximum transaction performance times, you can use this graph to determine whether the performance of the server is within the acceptable range.

X-axis

Elapsed time since the start of the run.

Y-axis

Average response time (in seconds) of each transaction

Breakdown options
  • Transaction Breakdown. You can view a breakdown of a transaction by right-clicking the transaction in the graph and selecting Show Transaction Breakdown Tree.

    In the Transaction Breakdown Tree, right-click the transaction you want to break down, and select Break Down <transaction name>. The Average Transaction Response Time graph displays data for the sub-transactions.

    For more details, see Transaction Breakdown Tree.

  • Web Page Breakdown. To view a breakdown of the Web page(s) included in a transaction or sub-transaction, right-click it and select Web Page Diagnostics for <transaction name>.

    For more information on the Web Page Diagnostics graphs, see Web Page Diagnostics Graphs.

Tips
  • Granularity. This graph is displayed differently for each granularity. The lower the granularity, the more detailed the results.

    However, it may be useful to view the results with a higher granularity to study the overall Vuser behavior throughout the scenario.

    For example, using a low granularity, you may see intervals when no transactions were performed. However, by viewing the same graph with a higher granularity, you will see the graph for the overall transaction response time.

    For more information on setting the granularity, see Getting more information from Graph Data.

  • Compare with Running Vusers. You can compare the Average Transaction Response Time graph to the Running Vusers graph to see how the number of running Vusers affects the transaction performance time.

    For example, if the Average Transaction Response Time graph shows that performance time gradually improved, you can compare it to the Running Vusers graph to see whether the performance time improved due to a decrease in the Vuser load.

Note

By default, only transactions that passed are displayed.
