[Agent] When the server does down

[Wido]

Hi,

I am trying to monitor some things through the agent, but i run into some troubles.

On a server i installed the agent and with agent.ping i check wether the server is online or not.

So i made a trigger: {host:agent.ping.last(0)}=0

Looks ok, but the problem is. When the host is down this item does not report 0, but i reports nothing. So the trigger will never go off.

Using simple checks is not an option in this case.

Using a trigger like: {host.agent.ping.last(0)}#1 works but the problem is i want to use sum() in some cases so i don't get a message for just one simple network hickup.

Does anyone what i should do?

Fixed!

The nodata() value in a trigger fixes it. The docs say it only works with a trapper, but that's not true

Can we use nodata to monitor the Agent Status

Just for information:

http://www.zabbix.com/manual/v1.1/config_items.php:

agent.ping | Check the agent usability. | Always return 1. | Can be used as a TCP ping. Old naming: "ping"

(an agent that's not working of course can't provide values to the server. That's why you'll never get a "0" )
