    Description

      It would be great to expose the count of fsync() since server startup via the serverStatus() similar to how the number of inserts/updates/delete/querys are exposed. I can/will modify mongostat to read it then. We really want to be able to see fsync's in the output, and it would be cool to see them in all our metrics. I have noticed in testing a 'stall' at points and I am pretty sure it's fsync() based on iostat, but I would like to see it explicitly in mongo.
