Does anyone know of a way to alert if the Zabbix Agent cannot collect CPU, Disk, Memory data etc from a host? I have an issue with several hosts that periodically hang and have to be power cycled. I'm working with several vendors on troubleshooting it but in the meantime I'd like to be able to send an email if the server hangs. When the server is in a hung state it's still pingable and the Zabbix Agent is still running but in the Graphs for the host there will be large gaps in the collected data. Any way for that to trigger an alert?
TIA
