MongoDB查询dbpath值

Question

Is there a way to get the value of dbpath of a running MongoDB instance via query, assuming I am connected as an admin? Unsurprisingly, it does not appear in the result of db.serverStatus command output.

Answer 1

After a bit of research, I found that it is actually pretty easy:

db._adminCommand("getCmdLineOpts")

gives you both argv and the parsed options that differ from the defaults, as far as I can see. You can access the dbpath variable via

db._adminCommand("getCmdLineOpts").parsed.storage.dbPath

regardless of where dbpath is defined if it differs from the defaults for your OS, which you most likely have to hard code according to the documentation of the dbpath config variable .
