Additional info

Hello.

MongoDb does not support collStats commad on collectin type view.

Example:

MYRS:PRIMARY> use local
switched to db local
MYRS:PRIMARY> show collections
oplog.rs
replset.election
replset.initialSyncId
replset.minvalid
replset.oplogTruncateAfterPoint
startup_log
system.replset
system.rollback.id
system.tenantMigration.oplogView
system.views
MYRS:PRIMARY> db.runCommand( { collStats : "system.tenantMigration.oplogView" } )
{
"ok" : 0,
"errmsg" : "Namespace local.system.tenantMigration.oplogView is a view, not a collection",
"code" : 166,
"codeName" : "CommandNotSupportedOnView",
"$clusterTime" : {
"clusterTime" : Timestamp(1654680040, 1),
"signature" : {
"hash" : BinData(0,"NqmNCz7AR6ZvHq05VXuEobarqyw="),
"keyId" : NumberLong("7106730213999902725")
}
},
"operationTime" : Timestamp(1654680040, 1)
}

Telegraf plugin try to gather_col_stats on collection type "view" , and also gets error :
