Zabbix 3.4: Is it possible for the agent to accumulate data if the connection with the APP is lost?

Question

I have installed Zabbix 3.4 by Oracle Linux 7.4

Is it possible for the agent to accumulate data if the connection with the APP is lost?

Answer 1

If by "APP" you mean Zabbix server, this is possible if you use active items. Agent will buffer values in the memory for a while and send them to the server when the connection is restored.
