Marcel Reutegger commented on OAK-7485:
---------------------------------------
Meanwhile the MongoDB Atlas documentation has been updated and now states the
{{serverStatus()}} command will return a {{ok=0}} response.
https://docs.atlas.mongodb.com/reference/unsupported-commands/#commands-with-special-behavior
That is, the behaviour reported in this issue is considered working as designed.
> DocumentNodeStore doesn't work with shared Atlas MongoDB replica set

> So, it seems that the serverStatus() command fails or doesn't return the
> required data. Similarly, when using mongo-cli:
> {noformat}
> $ mongo [redacted]
> MongoDB shell version v3.6.4
> MongoDB server version: 3.6.4
> MongoDB Enterprise [redacted]:PRIMARY> db.serverStatus()
> {
> "operationTime" : Timestamp(1525784995, 2),
> "ok" : 0,
> "$clusterTime" : {
> "clusterTime" : Timestamp(1525784995, 2),
> "signature" : {
> "hash" : BinData(0,"UbUJQri5/e/SsB8lBXmWPMaXwuk="),
> "keyId" : NumberLong("6547663121467572225")
> }
> },
> "metrics" : {
> "atlas" : {
> "connectionPool" : {
> "totalCreated" : NumberLong(56)
> },
> "bytesInWrites" : NumberLong(0)
> }
> }
> }
> {noformat}
> The {{ok}} field is {{0}}, but there's no error message. What's interesting,
> when using an older Mongo CLI, the command works fine:
> {noformat}
> docker run -it --rm mongo:3.4 /bin/bash
> root@e3fa93e33d32:/# mongo [redacted]
> MongoDB shell version v3.4.14
> MongoDB server version: 3.6.4
> WARNING: shell and server versions do not match
> MongoDB Enterprise [redacted]:PRIMARY> db.serverStatus()
> {
> "host" : "[redacted]",
> "version" : "3.6.4",
> "process" : "mongod",
> "pid" : NumberLong(3408),
> "uptime" : 1288779,
> "uptimeMillis" : NumberLong(1288779510),
> "uptimeEstimate" : NumberLong(1288779),
> "localTime" : ISODate("2018-05-08T13:15:48.586Z"),
