I have confuse about this timeout:

Is there reason for forced deletion of unused metrics?

Let's imagine a situation: Zabbix reads metrics at a certain interval, unused metrics are deleted if they are not used for a period of time (xhttp_prom_timeout).

I drew 2 cases when Zabbix will receive the same value, but we cannot say unambiguously whether these are new values or not.
