Troubleshooting
A list of the most useful troubleshooting tips for the Central Management Console (CMC).
If the sensor is not appearing at all in the Central Management Console (CMC):
- Make sure that firewall(s) between the sensor and the CMC permit traffic on transmission control protocol (TCP)/443 port (hypertext transfer protocol secure (HTTPS)), with the sensor as Source and the CMC as the Target
- Make sure that the tokens are correctly configured both in the sensor and the CMC
- Make sure that in the /data/log/n2os/n2osjobs.log file for connection errors
The Sensor ID is stored in the /data/cfg/.appliance-uuid file. Do not edit this file after the sensor is connected to the Vantage, or the CMC, since it is the unique identifier of the sensor inside Vantage and the CMC. In case a forceful change of the Appliance ID is needed, you will need to remove the old data from Vantage or the CMC by removing the old Appliance ID entry.
If an issue occurs during the setup of a sensor, you should:
- Delete the sensor, or
- Clear the sensor's data from Vantage or the CMC
