Some of the monitors are not showing in the uptime monitors of kibana

I have configured http monitors in the heartbeat monitors.d and after 2 days the monitors are not showing in the kibana. What may be the issue? Kindly help

Environment:
elastic version : 8.13.2
kibana: 8.13.2
heartbeat: 8.13.2

Hi @Subrahmanyam_Veerank,

Since you mention using monitors.d, I'm assuming you're running heartbeat with the legacy Uptime UI, is that correct? Can you verify through Discover o Kibana Dev Console that the monitors' data is still being ingested?
