Intermittent graphs in Zabbix

[t.ermolaev]

Hello! I understand that you're facing an issue with intermittent graphs in Zabbix while setting up infrastructure monitoring. All network node graphs connected through a proxy are displaying with interruptions, as shown in the screenshot. Additionally, these interruptions occur at the same time for all network nodes, regardless of the proxy they are connected to. Could you please advise on how to troubleshoot this?

Sorry for the post above. I'm having trouble setting up a Zabbix proxy server. All proxies send information to the server with breaks in time. Therefore, intermittent graphs are obtained (see screenshot). Please tell me how to find the reason? I am attaching screenshots with logs and information.
