In some cases, you can only use a remote MongoDB instance and cannot log on to the server on which the MongoDB instance resides, and a list of hosts and ports for a remote MongoDB instance is maintained on a single server. It then automatically adds the appropriate monitoring to the host and port via the Zabbix Auto-discovery feature.This article is from the Linux SA John blog, so be sure to keep this source http://john88wang.blog.51cto.com/2165294/15

built-in DNS, while somewhat similar in functionality, is not available for service registration and discovery itself is not highly usable, and there is a single point of failure. The service cannot be automatically registered with Autodiscover. The registration process and the anti-registration must notify the DNS server manually or through a applet. The service caller passes the internal domain name rotation Dns,dns automatically provides one of th
