The LoadRunner Request Tagging tool inserts a short method addDynatraceHeaderTest in your globals.h or globals.js file that populates the x-dynatrace-test header. It also parses your .c or .js files and automatically adds a call to this method before one of the key LoadRunner methods is called. Both C and JavaScript scripting languages are supported.
The addDynatraceHeaderTest method is called before the following methods: web_url, web_link, web_image, web_submit_form, web_submit_data, web_custom_request, web_browser, web_button, web_check_box, web_edit_field, web_elementweb_file, web_image_link, web_image_submit, web_list, web_map_area, web_radio_group, web_reg_dialog, web_static_image, web_table, web_text_area and web_text_link.
Modify LoadRunner scripts for Dynatrace
Record a LoadRunner Virtual User Generator (VUGEN) script and adapt it as needed. Refer to LoadRunner documentation for details.
Verify that the method addDynatraceHeaderTest has been added to your script
Configure request attributes
The header x-dynatrace-test is populated by the LoadRunner Request Tagging tool with the key/value pair listed below. These values can be captured by Dynatrace by defining request attributes. Not all key/value pairs need to be configured; only configure the one you're interested in for targeted analysis of your load tests.
Test Step Name is a logical test step within your load testing script.
The name of the transaction defined in the LoadRunner script. In case of nested transactions, the transaction names are concatenated.
LSN
Load Script Name - Name of the load testing script.
Either the name of the *.usr file or the value of the optional parameter -LSN
LTN
The Load Test Name uniquely identifies a test execution.
Value of the DynatraceLTN runtime attribute configured in LoadRunner
VU
Virtual User ID of the unique user who sent the request.
Example: 1, 2, 3, ...
PC
Page Context provides information about the document that is loaded in the currently processed page.
Contains the value of the first parameter passed to following functions: web_url, web_link, web_image, web_submit_form, web_submit_data, web_custom_request.
SI
Source ID identifies the product that triggered the request.
LoadRunner (fixed value)
Here is an example of how to configure the request attribute for the test step name (TSN):
In Dynatrace, configure the extraction rules for the custom HTTP Headers via Settings > Server-side service monitoring > Request attributes.
Select HTTP request header as the Request attribute source and enter the name of your custom HTTP header in the Parameter name field. Extraction of the test step name TSN from the x-dynatrace-test can be configured as seen below.
Run your load test from LoadRunner. The requests and PurePaths will be tagged in Dynatrace with the configured request attributes for targeted diagnostics and analysis.
There are different ways to analyze the data. Your approach should be based on the type of performance analysis you want to do (for example, crashes, resource and performance hotspots, or scalability issues). The request attributes set for the load test will help you filter the data. In this example, they are used to analyze the response time of the test step search journey paris:
