Zabbix server availability

[antani]

Minimizing scenario: I've got a zabbix server monitoring an active agent on a host.
If network goes down on host, zabbix server shows correctly that host is down.
What if network goes down on zabbix server? It shows uncorrectly that host is down. How can I make a trigger to monitor the state of the network on zabbix server? In this way I can make other triggers depending on this one.

You will have to set up a trigger to monitor the Zabbix servers network connectivity, and then define that trigger as a dependency of the trigger for the host. Then you will only get one alarm that the network for the Zabbix server is down.

...set up a trigger to monitor the Zabbix servers network connectivity...

How should i do that? The only way i figured out was to add a "Google" host and icmppinged it. But this probably is illegal (mind what if anyone do the same) and represent a banal workaround.

That depends on your network setup, and what kind of network issues you want to be preperred for.

You could for instance ping the default gateway, the gateway of your ISP, a NTP/DNS server at your ISP, some external server you may have etc.

I would to ping google.
How should i do that? adding google to hosts is a correct procedure?

Yes, either that or by using a external script for your Zabbix server host, which then does the checking.
