[SR-Users] Deletion of Prometheus metrics

[Marat Gareev]

Hello,

I have confuse about this timeout:
https://www.kamailio.org/docs/modules/devel/modules/xhttp_prom.html#xhttp_prom.p.xhttp_prom_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.
