Our compatibility matrix states PMM 1 supports MongoDB 5.0. But it seems the mongo_exporter bundled with PMM 1 server/client uses a MongoDB Go driver version which does not support authorization for connections to MongoDB 5.0.
The following error appears:
./mongodb_exporter -mongodb.uri="mongodb://mongodb_exporter:Admin123@localhost:27017/admin" -test ERRO[0000] Cannot connect to server using url mongodb://****:****@localhost:27017: server returned error on SASL authentication step: BSON field 'saslContinue.mechanism' is an unknown field. source="connection.go:84" ERRO[0000] Can't connect to MongoDB: Cannot connect using uri: mongodb://mongodb_exporter:AdminPa5sw0rd@localhost:27017/admin source="mongodb_exporter.go:104"If no login/password is specified, it can connect:
./mongodb_exporter -mongodb.uri="mongodb://localhost:27017/admin" -test { "Version": "5.0.5", "VersionArray": [ 5, 0, 5, 0 ], "GitVersion": "d65fd89df3fc039b5c55933c0f71d647a54510ae", "OpenSSLVersion": "", "SysInfo": "", "Bits": 64, "Debug": false, "MaxObjectSize": 16777216 }It seems the necessary changes were made in MongoDB Go driver 1.4.0 with commit https://github.com/mongodb/mongo-go-driver/commit/5d11dfab990acb6259bcaa6973af706d9403975d
The node_exporter in PMM 1 client should be updated to fully support MongoDB 5.0
