Dashboard for resource requests from waterfall analysis

JG3 · ‎09 Apr 2022

Experts,

Is there a way I could create a dashboard for the top time-consuming requests (document, XHR, resource requests) from their waterfall analysis (splitting them on application->page level) captured under RUM/Synthetic monitoring?

I would say that these options might help you:

In metrics, if you search for "synthetics", you will get some of the metrics below.
builtin:synthetic.browser.firstByte.load and builtin:synthetic.browser.event.firstByte.load are some of the metrics where you can get the First Byte (TTFB)values, which is normally the most important part for the document download
For XHR & resource requests, it seems that no corresponding metrics exist. But some creative metric calculation might give you a good estimation, like total time minus TTFB, for instance. Or you can use composite metrics, like builtin:synthetic.browser.event.networkContribution.load
If you want more details, you can even create metrics for a specific object. In the synthetic waterfall, in the object, click "Analyze over time", and then you will have the possibility to create a metric
With RUM data, you have much more options. To begin with, the application tile has the information you want.
In Metrics, you have a bunch of them. Search for "apps"

Thanks Antonio for quick reply. As advised, I am trying to figure out composite metrics, but is there a documentation somewhere I could refer to that could help me code the desired query with accepted syntax/metrics.

I wanted to have the representation where time consuming resource requests for a particular user action (like loading of PDP) could be seen. We can see it under waterfall Analysis but for business reporting purpose, wanted to have a kind of dashboard.

Have you checked the Data Explorer documentation pages? I include some for your reference:
