Sensor troubleshooting
Check the sensor's status in CertCentral
When a sensor isn't working, the first place to go is the Manage sensor page and check the status of the sensor. In the sidebar menu, click Discovery > Manage Discovery. On the Scan page, click Manage sensor.
Has the sensor been activated? (see Activate a sensor)
Has the sensor been started? (see Activate a sensor)
Has the sensor been shut down?
Have you tried restarting the sensor? (Restart a sensor)
Are there any error messages on the sensor start-up?
Check for network issues
If everything checks out on the Manage sensor page, check for network issues:
Can the sensor access the internet?
Are the cloud URLs reachable from the sensor? (Sensor diagnostic tool)
Is a proxy server required? (Configure a sensor to use a proxy server for communications)
Have you checked the sensor log?
Sensor diagnostic tool
Each sensor has a diagnostic tool to check for connectivity to the URLs configure in the license properties file.
Linux
Go to the installation directory and run ./diag.sh to check connectivity to the URLs configured in the license.properties file. Make sure you have root or administrative permissions to the server where the sensor is installed.
Windows
Go to the installation directory and run diag.bat to check connectivity to the URLs configured in the license.properties file. Make sure you have administrative permissions to the server where the sensor is installed.
Get a copy of the sensor log
If you still haven't found the problem, check the sensor log. You need a copy of the sensor log to share withDigiCert support if you end up needing help.
The sensor logs are located in the logs directory: '<install_dir>/logs'. The sensor.log file is the most recent log.
