Hello, Everyone!
This is regarding Proxy Negotiation and Stalled time metrics in Waterfall view for a Test. Manually, we’d launch the Chrome Developer tools and switch to Network tab, followed by clicking on any request and viewing the Timing tab.
Here, several metrics are recorded, including Stalled and Proxy Negotiation, if applicable. I’m not able to check the same in the waterfall view for a step in the results page.
Details:
Consider an example webpage, twitter.com:
I’m able to see Proxy Negotiation and Stalled times recorded in the timing tab.
Similarly, consider another example webpage, wikipedia.org:
Even for this webpage, I’m able to see requests that are logging Proxy Negotiation and Stalled times.
However, when I run a test on WebPageTest for any of these, either using a script or by entering the URL, I’m not able to check this information in the Result page in the waterfall view.
Example test: 250527_BiDcQD_HE3
Please let me know if these metrics are captured in WPT.
Moreoever, I have also have a local instance up and running for WPT Server and Agent. I’m able to debug the control flow for a test. If possible, point me to the file or subroutine where these metrics are/can be captured.
Thanks,
Suman.
