Description
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.
