  - Sensors
    The Sensors page lets you view all of the sensors that you have in your system.
  - Alerts
    The Alerts page shows all the latest alerts in the system. It lets you view the alerts in different modes, and carry out actions on the alerts.
  - Assets
    The Assets page shows all the physical components and systems in the local network environment and their associated details. It also lets you perform actions on those assets. Depending on the nodes and components involved, assets can range from a simple personal computer to an operational technology (OT) device.
  - Queries
    You can use the Nozomi Networks Query Language (N2QL) syntax to create complex data processes to obtain, filter, and analyze lists of information from the Nozomi Networks software.
  - Smart Polling in CMC
    The Smart Polling page gives you a read-only view of Smart Polling.
  - Arc in CMC
    Arc™ is a host-based sensor that detects and defends against malicious or compromised endpoints, and insider attacks. You can use Arc sensors to aggregate data for analysis and reports, either on-premises, or in the Vantage cloud.

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
