Description

English:
Certificate expiry warning (1 day). The certificate will expire in 1 day; the validity period is about to end, which may lead to authentication failure, service interruption and service access exception.
Recommended severity: critical. Recommended handling: complete certificate renewal and deployment immediately, and check the Certification Authority (CA) information and related service configuration; handle it as the highest urgency level and escalate to the on-duty owner.
Status: registered but unused. Not yet emitted by any monitoring component; when implemented, carry the list of dependent services that will be affected. The unused state shall be re-verified at each revision of this file.
Recommendation: prepare the replacement certificate and a rollback plan in advance, and verify the private key matching and the full chain deployment before switching, to avoid replacing an expiring certificate with a broken chain.
