Triggers not change the last value after lost connection with host

[ocarlossouza]

Hi, everyone.
I am new in monitoring world, my problem in this moment is:
I have a trigger to monitor the http protocol in the port 80, when only the http service down the trigger is activated, but when the network interface change for down to a host the http status stay with actived (1) in my zabbix server. I need that this status change for (0) or to empty for example.

Thank you for your attention

Do you have a host with only one item monitoring port 80?
If the host interface is down, the trigger is unable to evaluate the port because the item cannot receive new values.

Have you considered a simple check to monitor your host interface?

Hi,
Thansk for your reply.
I was testing net.tcp.service[http,,80] + agent zabbix, my client show error when I use only net.tcp.service[http,,80] + simple check.
Example: My http service is UP, but the item with simple check not return value (1) - When I change to agent check the valeu change to correct value.

with simple check you need to adda also hostname to parameters, not just protocol and port...
