get_browser_timing_header (Python agent API)



Generates a agent header for injecting the JavaScript agent.



The nonce parameter for nonced CSP support was added in Python agent version 9.4.0.

In Python agent versions 9.3.0 and below, the get_browser_timing_footer API was also required to enable browser timing. Starting with agent version 9.4.0 and later, this is no longer required.

This call returns the browser agent JavaScript header snippet that you can use to enable browser monitoring. You might use this if automatic instrumentation is not possible for your application, if you use a nonced content security policy, or if you want to collect browser data for only specific pages.

This is a manual alternative to automatic insertion of this JavaScript by the agent. To learn how to enable browser monitoring using this call along with get_browser_timing_footer, see Manually instrument browser monitoring.

This call must be called for every web request where you want to inject the JavaScript snippet. It cannot be called at global scope and cached.






Optional. The per-request, cryptographic nonce used by Content Security Policy (CSP) policies.

Return values

Returns the browser agent header JavaScript.


Manual browser monitoring instrumentation

See Manually instrument browser monitoring for instructions on how to use the header and footer calls.

CSP Nonce example
