What is a typical outcome if Zabbix items are left in an unsupported state?

When Zabbix items are left in an unsupported state, the typical outcome is a loss of critical monitoring capabilities. Unsupported items are unable to collect data or send necessary information to the Zabbix server. This means that any metrics or data that those items were supposed to track will not be monitored, possibly leading to undetected issues with the system or applications being monitored. Consequently, the absence of this data can result in a failure to identify and respond to performance problems, security breaches, or system outages in a timely manner.

Therefore, without addressing unsupported items, an organization risks significant gaps in its monitoring efforts, which can adversely affect overall system health and reliability.
