anyone knows how to query Azure App Insight to get analytics on client devices ? or OS ? I seem to be able to get good stats on Client countries but not devices
You can get a lot of noise due to minor OS and browser variations. Here's a query that pulls the same data, but also simplifies the values so they can be grouped by more easily
// scalars
let startDate = ago(31d);
let totalCount = toscalar(pageViews | where timestamp > startDate | count);
// query
pageViews
| where timestamp > startDate
| project
Browser = case(
client_Browser has "Firefox", "Firefox",
client_Browser has "Safari", "Safari",
client_Browser has "Chrome", "Chrome",
client_Browser has "Samsung", "Samsung",
client_Browser has "Edg", "Edge",
client_Browser has "Opera", "Opera",

| summarize Freq = count() by OS, Browser
| project OS, Browser, Freq, Percent = round(100.0 * Freq / totalCount, 2)
| order by Freq desc
