Currently, the Zabbix "Host Availability" column (in Data collection -> Hosts and Monitoring -> Hosts) strictly displays interface-based availability indicators: ZBX, SNMP, JMX, and IPMI.

However, in many enterprise environments, ICMP Ping is relied upon as the primary reachability and availability check for network devices, servers, and remote endpoints. In many cases, SNMP is used strictly for performance and statistical data collection, while ICMP dictates whether the host is actually "UP" or "DOWN".

Right now, if a host is being monitored exclusively via ICMP (Simple Checks) without a Zabbix Agent or SNMP, the Availability column remains completely blank, giving the false visual impression that the host is not being monitored or lacks availability tracking.

Proposed Solution: Introduce a new "ICMP" badge/indicator in the Host Availability column.

Suggested behavior and logic:

1. Triggering the Badge: The ICMP badge should appear when a host has active ICMP ping monitoring enabled (e.g., linked to items using icmpping, icmppingloss, or icmppingsec Simple Checks).

1. Status Colors:

• • Green (Available): When ICMP ping is successful (e.g., icmpping returns 1).

• • Red (Unavailable): When ICMP ping fails (e.g., icmpping returns 0).

• • Gray (Unknown): If the check is disabled or unsupported.

1. Coexistence: The ICMP indicator should coexist seamlessly alongside existing ZBX, SNMP, JMX, and IPMI indicators.

1. Customization (Optional but highly desired): Provide a toggle in the filter settings or user profile allowing users to choose which availability indicators are displayed in the Host list to avoid visual clutter.

 This feature would massively improve at-a-glance visibility for NOC teams and administrators. It provides a native, unified way to see ICMP reachability directly from the Hosts list, catering perfectly to environments where host reachability is validated by ICMP and standard interfaces (like SNMP) are only secondary data channels.
