how to determine the active check server is down

[allen_zhou]

Hi Guys,

I'm trying to moniter one server in different internal network from zabbix server so I used active check.

And I'm trying to use the nodata function to determine that server is down.
But seems can't work.
As I killed the zabbix_agentd on that server and this trigger was never triggered

Can anyone give me some advise?

This is the trigger I defined:
High Enabled Server {HOSTNAME} is unreachable {192.168.12.5:system.cpu.util[,nice,avg1].nodata(100)}<0


Thanks for anyone the reply

Best Regards,
Allen
