Perhaps on other 2.8.0-rcX versions, but at least on 2.8.0-rc4 the response of the command {serverStatus:1, oplog:1} to a config server now returns an error:
$ mongo some-config-svr-host:40031
MongoDB shell version: 2.8.0-rc4
connecting to: some-config-svr-host:40031/test
configsvr> db.runCommand({serverStatus:1,oplog:1})
{
"opcounters" : {
"insert" : 4960,
"query" : 21203,
"update" : 7866,
"delete" : 2023,
"getmore" : 7,
"command" : 16578
},
"opcountersRepl" : {
"insert" : 0,
"query" : 0,
"update" : 0,
"delete" : 0,
"getmore" : 0,
"command" : 0
},
... // all the other expected serverStatus subdocuments
"errmsg" : "exception: Problem reading earliest entry from oplog",
"code" : 17347,
"ok" : 0
}
configsvr>
This is a change from 2.6.x config server behavior, which used to simply ignore/exclude the "oplog" section from the serverStatus response and otherwise return normally.
