v4.0, v3.6
Start `mongoreplay monitor` (I used master built from source):
sudo mongoreplay monitor -i lo -e 'port 27017' -vvvv
Launch a a mongod 4.0.0-rc5 and connect to it with a mongo shell 3.6, note the following output:
14 Jun 18 14:06 -0400 (Connection: 1:13) command isMaster admin.$cmd Request:{"client":{"application":{"name":"MongoDB Shell"},"driver":{"name":"MongoDB Internal Client","version":"3.6.5"},"os":{"architecture":"x86_64","name":"PRETTY_NAME=\"Debian GNU/Linux buster/sid\"","type":"Linux","version":"Kernel 4.16.0-1-amd64"}},"isMaster":1}
14 Jun 18 14:06 -0400 (Connection: 1:13) +306µs reply Response:{"ismaster":true,"localTime":{"$date":"2018-06-14T18:06:48.595Z"},"maxBsonObjectSize":16777216,"maxMessageSizeBytes":48000000,"maxWireVersion":5,"maxWriteBatchSize":1000,"minWireVersion":0,"ok":1.0,"readOnly":false}
Now run the following commands:
db.test.insertOne({a:1})
db.test.findOne()
Note no output from mongoreplay.
Stop mongod 4.0.0-rc5 and start mongod 3.4.15, the following output is shown by mongoreplay for find and insert commands:
