## Transaction

Transaction is part of a session and usually consists of one or more pages. When testing web applications, an action resembles a page view.

The data shown here reflects the time spent on the execution routine of a transaction. Therefore, the transaction's runtime includes the runtime of a page (an HTTP operation, for instance) and the time required to prepare, send, wait for, and receive the data.

The error count defines the number of errors detected for a particular transaction such as timeouts or connection resets.

The Summary chart section comprises all data across Transactions to allow for a quick overview on transaction problems and performance. The tabs in this chart section contain single charts that refer to one transaction. In the following, all chart sections below visualize this information:

- Overview: Transactions Response Time, 95th Percentile and Errors
- Averages: Transactions Response Time, 95th Percentile and Errors.
- Count/s: Number of completed transactions per second.
- * : Numbers may be projected.
