Unreleased

[0.11.2]

Added

PMM-6361: New flag --suppress.collectshardingstatus can be used to disable the collection of Sharding Status. This flag is not set by default. On a large scale cluster it could help you to disable the mongoS exporters induced load to config tables. @vrazvan-adobe

Fixed

PMM-6361: runtime error: invalid memory address or nil pointer dereference, source="sharding_status.go:166" . When chunks collection is very big, the aggregate on it can take longer then default default 1000ms SocketTimeout. @vrazvan-adobe
