Having a replSetHeartbeat command's ReplSetHeartbeatResponse include the node's oplog head time would allow oplog windows to be calculated from replSetGetStatus and as a result recorded in FTDC.
For example:
MongoDB Enterprise replset:SECONDARY> db.adminCommand({ replSetHeartbeat: "replset", configVersion: 6, from: "192.168.2.100:27019", term: 3 })
{
"ok" : 1,
"state" : 2,
"v" : 6,
"configTerm" : 3,
"set" : "replset",
"syncingTo" : "192.168.2.13:27018",
"term" : NumberLong(3),
"primaryId" : NumberLong(1),
"durableOpTime" : {
"ts" : Timestamp(1642177853, 1),
"t" : NumberLong(3)
},
"durableWallTime" : ISODate("2022-01-14T16:30:53.341Z"),
"opTime" : {
"ts" : Timestamp(1642177853, 1),
"t" : NumberLong(3)
},
/** Something like this maybe **/
"oldestOpTime" : {
"ts" : Timestamp(1642177853, 1),
"t" : NumberLong(3)
},
/**********************************/
"wallTime" : ISODate("2022-01-14T16:30:53.341Z"),
"electable" : true,
"$clusterTime" : {
"clusterTime" : Timestamp(1642177853, 1),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
},
"operationTime" : Timestamp(1642177853, 1)
