SMTP & SNMP Alerts
When configuring SMTP/SNMP alerts on Elastifile management, you may want to use SMTP/SNMP server FQDN.
By default Elastifile management uses the DNS server published by the DHCP server, if the SMTP/SNMP server FQDN is private, the Elastifile management will not resolve the SMTP/SNMP server ip.
By default in GCP the DNS server used by the instance will be - 169.254.169.254
To configure the DNS on Elastifile management, please use following KB.
To check the DNS configuration, from Elastifile EMS instance try pinging SMTP/SNMP server FQDN, and then telnet the server FQDN on the correct port.
