Currently, the connPoolStats will only get stats from the extern pool object. This is linked to the pool ScopedDBConnection uses and it does not include the shardConnectionPool.
Add a new command called "shardConnPoolStats" which will show information on the per thread (incoming connection) connection status. Sample output for a sharded cluster with a single replica set below:
mongos> db.runCommand( { 'shardConnPoolStats': 1 } )
{
"hosts" : {
"test-rs0/dan-tm2:31100,dan-tm2:31101,dan-tm2:31102::0" : {
"available" : 0,
"created" : 2
}
},
"replicaSets" : {
"test-rs0" : {
"hosts" : [
{
"addr" : "dan-tm2:31100",
"ok" : true,
"ismaster" : true,
"hidden" : false,
"secondary" : false,
"pingTimeMillis" : 0
},
{
"addr" : "dan-tm2:31101",
