With the introduction of the $currentOp aggregation stage, users have the ability to obtain a list of operations running on Secondaries in a sharded cluster by setting the appropriate readPreference. However, this will only provide the operations from a single eligible Secondary in each shard, and the standard approach to more fine-grained targeting - using replica set tags - is both onerous and does not satisfactorily address this shortcoming.
Add a new flag to $currentOp which, if set, stipulates that it should target every data-bearing member in each shard and return an exhaustive list of all operations running anywhere in the cluster.
