APEX

That's how I use it. (Though it's not the entire time the user may be waiting. Networking lag...)

And I marry this with frequency, and compared medians & averages to find those that are used often, occasionally slow, frequently slow, rarely used, etc.

Thanks Scott!  Do you have an example of a query where you've married it with frequency?

Yes, I should have clarified further. I think I used an odd choice of words

Here I'm just looking at how often the page was used during the day.

select

to_char(view_date,'hh24') dt

,count(*) c

,min(elapsed_time) min

,round(median(elapsed_time),2) median

,round(avg(elapsed_time),2) avg

,max(elapsed_time) max

,round(avg(elapsed_time)-median(elapsed_time),2) diff

from apex_workspace_activity_log

where view_date > sysdate-2 -- last two days

and application_id = :APP_ID

and page_view_type = 'Rendering'

group by to_char(view_date,'hh24')

order by dt desc

I find it interesting how the outliers tend the average away from the median as the count drops.

And you could do what some of the app builder reports do and multiple them out to find weighted averages / medians

-- top pages

select r.application_id||':'||r.page_id page

,p.application_name||' - '||p.page_name page

,count(*) c

,count(distinct apeX_user) unique_users

,sum(elapsed_time) sum_elapsed

,count(*) * sum(elapsed_time) weighted_sum

,count(*) * median(elapsed_time) weighted_median

,max(elapsed_time) max_elapsed

,round(avg(elapsed_time),3) avg_elapsed

,median(elapsed_time) median_elapsed

,count(case when page_view_type = 'Rendering' then 1 end) render

,count(case when page_view_type = 'AJAX' then 1 end) ajax

from apex_workspace_activity_log r

join apx_application_Pages p

on p.page_id = r.page_id

and p.application_id = r.application_id

where r.application_id = :MY_APP

group by r.application_id||':'||r.page_id

,p.application_name||' - '||p.page_name

order by c desc

In this case, I might ask why page 5 has a higher median than 1 or 3 (particularly since I'm aware of what those pages do...)

I love this data.

These are great examples - thank you so much Scott!

I'm not sure if this is a silly question but is each elapsed_time entry for initial page load only or also for page refresh (such as generating a new chart or report on the same page with new filters)?

I don't think it's a silly question. If I remember correctly, the page_view_type column was introduced in APEX 5.0 to help answer this question.

So you get separate records for each, and check out the request_value column to give it some more context.
