Where does Frontend time show on User action contributors breakdown?


Hi Experts, I am trying to understand the contributors breakdown for a load action and couldn't understand where does the frontend time show on the breakdown.

Question#1 -> Trying to chart with frontend time. If the frontend time metric is not available in applications metrics for a custom chart, suggest what is the other metric we can consider for measuring estimated frontend time?

Question#2 -> Please take a look at the screenshots, and help me in finding the frontend time from the breakdown.

Question#3 -> Appreciate if you explain how Dynatrace measures the Frontend time?

thanks @Yos N. and I am trying to find where does Frontend time represent on User action breakdown?

I don't think so @Yos N. User action duration includes Frontend time and Network contribution excludes Frontend time.

You can chart this via the USQL - this is the best option as it stands now. As provided in the previous question string


Your are right @Chad T. here it goes:

Thanks for the query this is very helpful. Do you know if its possible to get the median value of each column? I am still new to doing queries

Great! Thanks @Chad T. @Yos N. Can you help me in finding the answer for Question#2?

the Waterfall would be likely the best place to get a further break down of the times, rather than the infographic you provided - the frontend time User Action Duration - Server Consumption - Network Consumption. (Time spent in the browser on executing Javascript and rendering the page.) The waterfall analysis mainly provides a further break of the timings. Waterfall will generally show you client side, which includes front end timing, but front end is not easy to evaluate exactly as its not only related to front end performance but also user device/computer as well. I would say front end timing is only relevant when viewing it with the Waterfall analysis.


Understood. Thanks @Chad T. for explaining it well.

you're very welcome!



1.5S is the time the page "need" to be ready for customer usage (Visually complete)

2.6S is the time needed to load all page component (User action duration)

Visually complete: Time spend from the Browser to render the page (user can click and perform actions)

User action duration: Full time spend from the Browser in order to load all page component.

Think about OnePage application loading all javascript deferred from other component (Above the folder Technic) .. user is working but page is still loading component from the server. (very long long page where user scroll or click next for a workflow page)

Note: Cached page can have less user action duration then visually complete ( check drill down)

So in a nut.. all depend about what you're looking for

Note: data aggregation from USQL can be different from data on this section. (due to retention period and different logic used for time series)



Thanks @Domenico B. this is very helpful for me to understand it better.


I agree that these metrics are useful and don't understand why it's not available for a given page as a dashboard metric. here is a good article that explains the value of this metric
