(Optional) Verifying Certificate Validity

If TLS authentication is enabled, pay attention to the certificate validity period. Ensure that the certificate validity period and renewal schedule are well-planned, and update the certificate prior to its expiration to mitigate potential security risks. MindIO TFT periodically inspects the certificate validity period. The default inspection period is 7 days, and the default notification time for certificate expiration is 30 days. If a certificate expiration risk is detected, a WARNING alarm is printed in the log configured by the environment variable TTP_LOG_PATH. Pay attention to and handle the alarm in a timely manner.
