Description
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 .
