Hi Shrawan, it seems like there's a bug in the status collector for MongoDB.
Could you please share your MongoDB configuration (probably /etc/mongod.conf) and share the output of the db.serverStatus() <https://docs.mongodb.com/manual/reference/method/db.serverStatus/> command in the mongo shell <https://docs.mongodb.com/manual/mongo/>. You can probably get the latter information with the following command: echo 'db.serverStatus()' | mongo > server-status.txt After running this command, the required data should be in the server-status.txt file.
