I know, it's possible to export data from an App Insight account. Is it possible to import data (telemetry) into App insights account from another App insights account?
回答1:
There's no way to import from one to another. you could by exporting it, swapping out the ikey and sending it again, but it's probably not worth that extra work. but even doing that has limitations on how "old" the data can be (you can't export 30 days and import and get 30 days in the new resource. any data more than ~48h old (last time I checked) will be rejected.
you can do queries across multiple application insights resources, either via the logs tool or workbooks, so it's probably easier to just query both resources instead?
