As soon as you have a new node in the Cloud Zabbix will automatically start collection of performance and availability data of the

process that may collect data on behalf of Zabbix server, taking some processing load off of the server node - a full Zabbix server configured as an element within a hierarchy of distributed monitoring; it are calculated in a similar way, but this also depends on a total number of child nodes linked to a node. Time synchronisation It is very important to have precise system date on server with Zabbix running Parameter Description Group name Enter a unique host group name. The name must be unique within a Zabbix node. Hosts Select hosts, members of the group. A host group may have zero, one or more hosts. 2 Inventory
