Note
The Specifications of the Service inhibit contents check/deletion/downloading of the certificates stored on the Load Balancer (NetScaler VPX).
https://ecl.ntt.com/en/documents/service-descriptions/rsts/network/loadbalancer/loadbalancer.html
As certificates created on the NetScaler are not downloadable to our side due to the specifications above, operation check is conducted by importing certificates created on an external server to the NetScaler.
However, as you cannot check contents of, delete, or download certificates once imported to the Load Balancer (NetScaler VPX), we would recommend to store the certificates in the environment of your side in case of need for re-importing the certificate such as when rebuilding.

Tab「Configuration」 System > Auditing
You can check the system logs.
Log Levels: Customer can select log level to be output in case of selecting CUSTOM.
