1.4.5 agent active check problems

[Rrx]

Just set up an proof of concept zabbix installation, to replace nagios/cacti.
Main goal is to have most checks to be done as active checks.
Now I have problem with host availability
* Monitored hosts are shown as Unreachable, availability on Hosts screen is either Not available or Unknown.
server log says: Active parameter [status] is not supported by agent on host [xxx]

How availability of these hosts can be checked? Is there a way to detect missing agent updates and create triggers based on that?

Many thanks,
Riho.

Thanks, infinity500!
I have set agent.ping to have correct Unreachable trigger.
However, this does not affect host availability status on Hosts configuration screen, nor "Hosts info" panel. These hosts are still reported as "Not available" or "Unknown". How is host availability determined?

Figured it out finally myself. For availability, at least one passive check is needed. Simple check for tcp connection is what I use and it keeps zabbix happy :)

But there is another problem, how can I disable templates appearing as not available host. Error on Hosts screen is "Cannot resolve []".

For availability, at least one passive check is needed.It is not quite correct. You may use combination of trigger function nodata() with an active checks for host availability.
