Zabbix proxy with active agents?

[bbrendon]

It seems zabbix doesn't support active agents with proxy servers. Is this correct? If so, when will it be supported?

If I'm incorrect, what am I doing wrong?

In the proxy server log:

 10047:20081223:190005 Send list of active checks to [172.x.x.36] failed: host [hostWithActiveAgent] not found

Proxy does support items of all types including active items, SNMP, external (simple) checks, everything. Check if your host is defined and configured to be monitored by the proxy.

Ah ha!
Found the problem. I needed to restart the proxy once I added the agent to the proxy in the GUI.

You don't have to restart anything. ZABBIX Proxy automatically refreshes configuration every one hour by default, the period can be changed.

[bbrendon]

Hmmm. Can you make this dynamic? So if the proxy gets a new agent request then it goes and fetches its configuration?

I would hate to set ConfigFrequency=60.

Basically, I see the problem when you add a new agent to be monitored, its not going to work AND will be marked as down for an hour until the proxy grabs the new data. I also don't see the efficiency in setting ConfigFrequency=60.

Put that on the wishlist

Well, what happens if the agent is not known to ZABBIX? It would trigger configuration refresh forever...

[bbrendon]

I have an answer for everything...

Just ignore the agent if the proxy doesn't find a reference in 3 tries.

It's ok but ....

Alexei,


Actually (I undesrtood that) zabbix_agentd ask for active itens to first server in 'Server" (directive in zabix_agentd.conf).

If we change proxy to monitoried hosts we need change 'servers order' in zabbix_agentd.conf to get active checks working.

Is it a feature or a bug ?

zabbix agent always asks first server in the option "Server" for active item list.
thus if you want for the agent to ask & report to a proxy, proxy ip must be the forst one specified in that parameter.

edit : forgot to mention that it "works as expected", thus in your terminology it's a feature

OK but ...

If we have two or more proxies and want switch hosts between this proxies ... we need change 'zabbix_agentd.conf' too. It's expected ? Sounds bad if zabbix_agent ask for all 'servers' about active items ?

[richlv]

as i noted, it should ask only the first server (and only if active checks are enabled, of course).

Just use virtual IPs and you're all set.

And you need to change the config just for the active checks.

If the agents are configured right they'll allow access from all
zabbix servers (for passive checks).
Just put the real IP addresses of your proxies
after the first one in the same text line of zabbix_agentd.conf.

Edit: Don't change the implementation. It's OK for now.
What would be an idea is to use broadcasts to find the zabbix server.

HTH,

Norbert.
