Title: Alarm for manager_health.missing_dns_entry_for_manager_fqdn Event ID: manager_health.missing_dns_entry_for_manager_fqdn
Alarm Description
Purpose: The purpose of this alarm is to inform the user that the DNS entry for the Manager FQDN is missing.
Impact: The DNS configuration for specific manager node is incorrect. The Manager node is dual-stack and/or CA-signed API certificate is used, but the IP address(es) of the Manager node do not resolve to an FQDN or resolve to different FQDNs.
Environment
VMware NSX-T Data Center
Resolution
Steps to resolve For 4.1.0 and higher
Ensure proper DNS servers are configured in the Manager node.
Ensure proper A records and PTR records are configured in the DNS servers such that reverse lookup of the IP addresses of the Manager node return the same FQDN, and forward lookup of the FQDN return all IP addresses of the Manager node.
Alternatively, if the Manager node is not dual-stack, replace the CA-signed certificate for API service type with a self-signed certificate.
