# DevWeb runtime settings

The DevWeb runtime settings pages enable you to configure runtime behavior for DevWeb scripts.

## About DevWeb runtime settings

The runtime setting views include descriptions of the settings. Hover over a field to see the description in the Tips box at the bottom of the page.

Additional information for some of the DevWeb runtime settings is given below.

You can configure the DevWeb runtime settings manually, by editing the files for the script. For details, see the Help Center.

DevWeb runtime settings views:

View | Description
--- | ---
DevWeb Settings | Enables you to configure and customize general runtime settings for DevWeb scripts. These include sections for the following: Log. Includes log mode and log level. Proxy. Includes PAC support, proxy server details and authentication credentials, authentication type (basic or NTLM), and excluded hosts. Replay. Includes several advanced replay options such as : Snapshot generation Cache simulation Integrated authentication Simulate a new user for each iteration Resolve DNS per Vuser, enabling the storage of the obtained IP address in the internal Vuser cache. It is resolved again either when expired, or between iterations when Simulate a new user for each iteration is enabled. (Available in version 25.3 and later) Dynatrace monitoring (see Dynatrace integration) HTTP. Includes keep alive and connection timeouts, set HTTP headers to appear in canonical form, and ability to set HTTP/2 and HTTP/3 support for replay. Note: If the server refuses the HTTP/3 connection, DevWeb will fall back to the next enabled HTTP version. When HTTP/3 is enabled, DevWeb will use TLS1.3, regardless of the maximum TLS version defined in the runtime settings. SSL. Includes ignoring bad certificates and the maximum TLS version. Encryption. Data encryption key location. VTS Proxy. Includes information for VTS proxy server connection.
Run Logic | Enables you to define run logic for actions. For details, see Run logic view. Tip: Check out the video: Define run logic for DevWeb scripts.
Pacing | Enables you to define timing between iterations. The pacing tells the Vuser how long to wait between iterations of your actions. It can be set to delay or interval pacing, with fixed or random intervals.
Think Time | Enables you to define think time options, to control how the Vuser uses think time during script execution. Think time defines for how long the Vuser pauses its execution at the point where think time is used. This is to emulate a user pausing before moving on to the next step in a business process.
Additional Attributes | Enables you to provide additional user arguments for the DevWeb script. By adding the arguments in this view, you can pass external parameters that can be used within the script. You specify the name and value for each command line argument. They are added to the rts.yml file for the script, and they can be retrieved at a later point during the test run using load.config.user.args.
Additional Log Settings | (Available in Controller.) Enable the collection of additional logs when the script is running in a scenario. The logs provide data that can help to troubleshoot issues. This field is disabled by default; to conserve resources, enable only when needed.

## Dynatrace integration

DevWeb data can be pushed to the Dynatrace monitor on the AUT server during the test run, enabling correlation of the web server data collected by the Dynatrace agents, with the data provided by the DevWeb tests. When the integration is enabled, an additional header containing test transaction information (x-dynatrace-test header) is added to each web request.

To enable the integration, in the DevWeb Settings view > Replay section, select the check box for Enable Dynatrace Request Tagging.
