Get count of “loglevel” for each “name”

Question

For example I have following collection:

db.names.find({})

{ \"_id\" : ObjectId(\"5768d9b4bc6f464899594570\"), \"name\"          


        

Answer 1

If I understand correctly, you want the sum of loglevels against each name. shouldn't this help?

   db.names.aggregate([{$group:{_id:{name:"$name",loglevel:"$loglevel"},sum:{$sum:1}}}])
