What is wrong, what privileges are missing for siteRootAdmin
Thanks.

Hi @andrii88-ku
I ran into a similar issue with Unauthorized for $indexstats. I discovered this error only appeared for secondaries, not the primary. I believe MongoDB doesn't provide these infos on secondaries, the same is true for anything that requires a secondary. The "unauthorized" is a red-herring.

If this is the case for you too, I think percona should make sure to not request metrics from replicas that won't be able to provide answers.
