Explain output for find commands include a serverInfo object that contains version information:
> db.foo.explain().find().finish().serverInfo
{
"host" : "MacBook-Pro.local",
"port" : 27017,
"version" : "4.1.4",
"gitVersion" : "2f4b5918497b09a226a3ec5dcff930edd52ea1e9"
}
However, this information is not available for aggregation commands:
> db.foo.explain().aggregate([])
{
"stages" : [
{
"$cursor" : {
"query" : {
},
"queryPlanner" : {
"plannerVersion" : 1,
"namespace" : "test.foo",
"indexFilterSet" : false,
"parsedQuery" : {
},
"queryHash" : "8B3D4AB8",
"winningPlan" : {
"stage" : "COLLSCAN",
"direction" : "forward"
},
"rejectedPlans" : [ ]
}
}
}
],
"ok" : 1
}
This would be helpful to include for more complete information when troubleshooting .
