I'm trying following query:

db.getCollection('permission').aggregate([
   { $match: { "accountId": "my-account" } },
   { $group: { _id: "$accountId", "totalCount": { $sum: 1 } } }
])

It's showing total account wise but I want total count of all document in permission.

Try to put null in _id as:

db.getCollection('permission').aggregate([
   { $group: { _id: null, "totalCount": { $sum: 1 } } }
])
