We will create new serverStatus sections:
opReadConcernCounters: {
available: <num>,
linearizable: <num>,
local: <num>,
majority: <num>,
snapshot: <num>,
none: <num>
}
The sum of these counters should be opCounters.query (note that this means we will not include getMore commands, since these inherit the readConcern from the originating command).
opWriteConcernCounters: {
insert: {
wmajority: <num>,
wnum: {
"0": <num>, // only generate these fields if they are used
"2": <num>,
...
},
wtag: {
"tag1": <num>, // only generate these fields if they are used
"tag2": <num>,
...
}
none: <num>
},
update: {
wmajority: <num>,
wnum: {
"0": <num>, // only generate these fields if they are used
"2": <num>,
...
},
wtag: {
"tag1": <num>, // only generate these fields if they are used
"tag2": <num>,
...
}
none: <num>
},
delete: {
wmajority: <num>,
wnum: {
"0": <num>, // only generate these fields if they are used
"2": <num>,
...
},
wtag: {
"tag1": <num>, // only generate these fields if they are used
"tag2": <num>,
...
}
none: <num>
}
}
The sum of the counters for opWriteConcernCounters.insert should be opcounters.insert, and similarly for the other operations. Note that the j value is ignored, so {w: 1, j: true} and {w:1, j:false} are both counted in w1.
