Description
The documentation for locks are unclear and in places wrong.
http://docs.mongodb.org/manual/reference/server-status/#server-status-locks
This page says that
"A field named . holds the first document in locks that contains information about the global lock as well as aggregated data regarding lock use in all databases."
My understanding from discussion in dev is that the "." database will be for the actual global level lock, rather than an aggregate.
Regarding mongostat - http://docs.mongodb.org/manual/reference/mongostat/
The doc's say "This value represents the amount of time the database had a database specific lock" - can we add some clarification to show that its only the database listed and not all databases.
Examples of these values would help immensely.
