1. Check the status of the MongoDB and server using the following commands:
To check MongoDB status: service mongod status.
To check server status: service cloudmon-controller@server status.
If either of them is inactive, restart them using the following commands:
To restart MongoDB: service mongod restart.
To restart the server: service cloudmon-controller@server restart.
2. Check the disk utilization. If the disk utilization is high, it may cause issues. In such cases, clear old/unwanted logs to free up disk space.
