Certificate Audit
The Certificate Audit feature provides a view of certificates that are on BIG-IP systems and provides a mechanism to notify users when certificates are nearing expiration.
By default, the audit feature manages only certificates that are in use by a virtual server on the BIGIP systems.
Certificates that are not in use by a virtual server can be added using the configuration form.
Additionally, certificates, which are in use by a virtual server, can be filtered out with the configuration form.
The certificate information, for each device group, will be populated in accordance to its configuration nightly, but if any certificate information has changed, you will need to manually refresh the device group’s certificate data.
Click on the expand button of the certificate to view its detailed attributes and associated information
To modify a device group’s certificate management configuration, go to the device groups tab and select configuration in the top right corner.
