- Username / passwordAn account with the clusterMonitor role only, logged in with SCRAM-SHA-256.
无需账户。
需要开放的网络端口
27017/TCPMongoDB protocol (default port, plain or TLS)
设置步骤: Create a read-only MongoDB account
In mongosh, create the account with the clusterMonitor role.
use admin db.createUser({user: "dumbmonit", pwd: passwordPrompt(), roles: [{role: "clusterMonitor", db: "admin"}]})In DumbMonit, enter the address of one mongod, for example db1.lan:27018, then the user and its password.
In a replica set, add every member as its own monitor.
Tick TLS if the server requires it.
注意. A mongodb+srv:// address is not resolved (enter each member's host), and MongoDB older than 3.6 and mongos routers are not supported.
