Please check documentation: https://www.zabbix.com/documentation/current/en/manual/web_interface/frontend_sections/data_collection/hosts

Note: If Zabbix agents older than 6.2.x are used, they are not sending any active check heartbeats, so the availability of their hosts will remain unknown.
Active agent availability is counted towards the total Zabbix agent availability in the same way as a passive interface is. For example, if a passive interface is available while the active checks are unknown, the total agent availability is set to gray (unknown).
