Yesterday our Nutanix CE cluster suffered a node loss (onboard NIC went offline somehow, investigating), HA failover performed correctly, but I had Zabbix monitoring cluster API 2.0 which did not state there is a problem. The only difference was that the host stopped being visible in the discovery by its proper name and remained only by IP, every other reading were "normal" and "not degraded" and even cluster state was reported "normal" during host effective downtime. WTF?!
Also, WTF is with re-posting a question to another forums when asked to? Do you maybe have crosslinks allowed to ask the same question in a different subset of forums?
