Description
Currently the counts of migrated documents are only recorded in the mongod logs, and not in config.changelog:
2017-06-12T19:05:49.897+0000 I SHARDING [conn1028707] moveChunk data transfer progress: { active: true, sessionId: "...", ns: "...", from: ".../...:27018,...:27018,...:27018", min: { ... }, max: { ... }, shardKeyPattern: { ... }, state: "steady", counts: { cloned: 53195, clonedBytes: 68335232, catchup: 0, steady: 0 }, ok: 1.0 } mem used: 0 documents remaining to clone: 0

2017-06-12T19:05:49.992+0000 I SHARDING [conn1028707] about to log metadata event into changelog: { _id: "...", server: "...", clientAddr: "...", time: new Date(...), what: "moveChunk.commit", ns: "...", details: { min: { ... }, max: { ... }, from: "...", to: "..." } }
|
It would be useful if the final counts could also be saved in the moveChunk.commit changelog document, ie:
{
|
"_id" : "...",
|
"server" : "...",
|
"clientAddr" : "...",
|
"time" : ISODate(...),
|
"what" : "moveChunk.commit",
|
"ns" : "...",
|
"details" : {
|
"min" : {
|
...
|
},
|
"max" : {
|
...
|
},
|
"from" : "...",
|
"to" : "...",
|
+ "counts" : {
|
+ "cloned" : 53195,
|
+ "clonedBytes" : 68335232,
|
+ "catchup" : 0,
|
+ "steady" : 0
|
+ }
|
}
|
} |
