Azure Monitor for WVD generates a lot of data in Log Analytic Workspace

breakplease 

To be honest mine cost nothing (Beside alerts costs), but I log only the critical stuff that I want.

Note that, It might lead to empty charts from the Microsoft exemple.

It really come down to what, how often and the data retention that will grow your analytic size.

Like Tom said, I strongly suggest that you put a datacap per day of what you want to pay.

After that, if you miss some data, now it is the time to thinking about stop logging stuff that you don't need.

I made a query for you where you can pin point, which table is pumping so much data.

(It will probably be a VM monitoring that you will have to tune down or remove some counters.)
