Install and persist Grafana Zabbix plugin 6.5.0, provision the internal Zabbix datasource, and add a fleet dashboard modeled on client 02 Telemt panels. Add an active-agent Zabbix 7 template plus a 30-second sanitized collector for active IP count/list, connections, traffic, and uptime. Active checks avoid inbound polling of client-private Docker hosts. The exact Zabbix host names and required ZABBIX_API_TOKEN Portainer variable are documented. Compose validation passed on 10.0.0.6; the live plugin registered successfully under Grafana 13.1.0.
