`queryHash` field introduced in slow query logs in v4.2 is available only in `mongod` logs and not in `mongos` logs. The documentation does not have any mention of relevant behaviour. Is this expected or requires any configuration change?
Sample mongos slow query log:
{"t":{"$date":"2020-12-31T02:19:33.680+00:00"},"s":"I", "c":"COMMAND", "id":51803, "ctx":"conn128","msg":"Slow query","attr":{"type":"command","ns":"xxxx.companyPriority","command":{"find":"companyPriority","filter":{"_id":{"$in":[{"$oid":"5319df10e4b0f7e16602a313"}]}},"$db":"xxxx","$clusterTime":{"clusterTime":{"$timestamp":{"t":1609381171,"i":2}},"signature":{"hash":{"$binary":{"base64":"C2cNRe4vAhiBs97T6VYXIYYU1Ck=","subType":"0"}},"keyId":6877905033757720578}},"lsid":{"id":{"$uuid":"ba72a15f-2568-43e9-8c9a-abd7bd2aa6be"}}},"nShards":1,"cursorExhausted":true,"numYields":0,"nreturned":1,"reslen":278,"protocol":"op_msg","durationMillis":2007}}
