1. Clean up the browser cache and restart the internet browser before starting the troubleshooting

Verify that the pages you are interested to monitor are not being excluded by includeURLsRegex
introscope.agent.browseragent.dxchost=<DxC host name>
introscope.agent.browseragent.dxcport=<DxC port>
3.- Review the Introscope agent logs to verify the snippet file location is correct and valid.

The Snippet file instruct the Browser Agent where to download the BA.js profile and the BAExt.js file
By default introscope.agent.browseragent.autoInjection.default.snippetLocation=../config/default.basnippet
If there is a problem a message will be reported in the agent log as below for example:

[ERROR] [IntroscopeAgent.BrowserAgent] C:\CA\apm\wily\test.basnippet, this file is empty or not readable.
4.- Make sure you are using a supported browser. Check the Product Compatibility Matrix for supported browsers. 
5.- Check if the snippet is inserted in the correct place.
The snippet is always inserted after the <head> tag in the source page. Open the page you need to monitor, right click, select “View Source Page”, verify that the snippet  has been inserted, below example:

NOTE: If content encoding type is gzip the auto injection is stopped and the response is not edited.


6.- Verify that the BA.js file is downloaded from the Digital Experience Collector as specified in the snippet.js file


In your browser press F12, go to the “Network” tab, open the page you would like to inspect, verify that “ba.js?agent=browser” appears in the list and the content is readable.


7.- Check the browser console for any error or warn message.


Enable “browserLoggingEnabled” in the <DXC_HOME>/browserAgent/wa/ba/profile/default-tenant/default-app/profile.json. By default logging is disabled.

Push the updated profile to DxC(s) by running:  :

<DXC_HOME>/bin/ -baDir <DXC_HOME>/browserAgent/wa

Make sure DxC is up and running. 


In your browser press F12, go to the “Console” tab, refresh the page, you should see [CA Browser Agent] entries as below, make sure no ERROR messages are reported

9.- Check if the browser is dropping the POST requests (for example, CORS is disabled), see


10.- Check the appropriate metrics features are enabled (Page, JavaScript Function or AJAX).

"pageLoadMetricsEnabled" : true,
"ajaxMetricsEnabled" : true,

 Push the updated profile to DxC(s) by running:  :

<DXC_HOME>/bin/ -baDir <DXC_HOME>/browserAgent/wa

11.- Check if the defined thresholds are not met (Page, JavaScript Function or AJAX).
For example, if Soft Page navigations or “route” changes are being excluded because changes are too fast, then try reducing ajaxMetricsThreshold
Open the <DXC_HOME>/browserAgent/wa/ba/profile/default-tenant/default-app/profile.json
Adjust the value as required.

"pageLoadMetricsThreshold" : 100,
"ajaxMetricsThreshold" : 100,

Open the <DXC_HOME>/browserAgent/wa/ba/profile/default-tenant/default-app/profile.json
Enable below property
