I prefer another approach if you are using mongo shell  First as the another answers  use my database name then  db getCollectionNames   map   name    gt     name   db name  find   toArray   length      This query will show you something like this                               quot agreements quot    60                                       quot libraries quot    45                                       quot templates quot    9                                       quot users quot    19               You can use similar approach with db getCollectionInfos   it is pretty useful if you have so much data  amp  helpful as well

var collections   db getCollectionNames    for var i   0  i lt  collections length  i            print  Collection      collections i       print the name of each collection    db getCollection collections i   find   forEach printjson     and then print the json of each of its elements     I think this script might get what you want  It prints the name of each collection and then prints its elements in json
