Determine the situations when a user-initiated database session must be terminated. Note: The user running the commands shown below must have privileges with listSessions, killAnySession and impersonate action on the cluster. In the MongoDB shell, as an authenticated user, run the following command to list all user sessions: > use config > db.system.sessions.aggregate( [ { $listSessions: { allUsers: true } } Reference: https://docs.mongodb.com/v7.0/reference/operator/aggregation/listSessions/ Example output: { "_id" : { "id" : UUID("b3b50641-54c6-4d6d-a96e-a2239fadce3c"), "uid" : BinData(0,"Y5mrDaxi8gv8RmdTsQ+1j7fmkr7JUsabhNmXAheU0fg=") }, "lastUse" : ISODate("2021-09-23T23:34:43.951Z"), "user" : { "name" : "jsmith@admin" } } From the output identify the names of users whose sessions should be terminated. Using the user for each session to be terminated, run the following command (still in MongoDB shell). > db.runCommand( { killAllSessionsByPattern: [ { users: [ { user: <user>, db: <dbname> }, ... ] }] } ) Example to terminate user "jsmith@admin" sessions from example output: > db.runCommand( { killAllSessionsByPattern: [ { users: [ { user: "jsmith", db: "admin" } ] }]} ) To terminate all user sessions running on the database, run the following command (still in MongoDB shell): > db.runCommand( { killAllSessionsByPattern: [ ] } ) Reference: https://docs.mongodb.com/v7.0/reference/command/killAllSessionsByPattern/
