Description
In the output of printShardingStatus() / sh.status(), it would be good if there was a "mongos" section (eg. next to "shards"). This would show info about the "active" mongoses (as found by applying some appropriate threshold to the ping time values in config.mongos, eg. 2 mins before the most recent ping).
For example, if verbose is false, then just a basic count and list of the mongos versions found:
> sh.status()
|
--- Sharding Status ---
|
sharding version: {
|
"_id" : 1,
|
"minCompatibleVersion" : 5,
|
"currentVersion" : 6,
|
"clusterId" : ObjectId("552720847d69a9cc3ebd4313")
|
}
|
shards:
|
{ "_id" : "shard1", "host" : "shard1/s11:27018,s12:27018" }
|
{ "_id" : "shard2", "host" : "shard2/s21:27018,s22:27018" }
|
+ active mongoses:
|
+ "3.0.3" : 4
|
+ "3.0.2" : 2
|
balancer:
|
...
|
databases:
|
... |
Or, if verbose is true, then one line for each active mongos (sorted by ping):
> sh.status(true)
|
--- Sharding Status ---
|
sharding version: {
|
"_id" : 1,
|
