Currently the counts of migrated documents are only recorded in the mongod logs, and not in config.changelog:

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:
