How to monitor agents via proxy

[kkoon]

Hi

I'm having problem monitoring agents via the zabbix proxy. The zabbix proxy is active and monitored by the zabbix server.

The zabbix agent is not accessible by the zabbix server in anyway. Firewall ports(Port 10050 and 10051) have been opened between the agent and the proxy.

But the status of the availability of the agent is still "Unknown". From the proxy server, i've did a zabbix_get to the agent and able to retrieve results.

According to previous posts, it is not really important to have the availability as Available. Can anyone confirm on this?
Even so, the web interface of the zabbix server is still not able to retrieve any data from the agent(monitored via proxy)


Please advise on what other files or parameters i would need to modify to get it working?

Thanks in advance!!!

More updates:

The proxy log file shows:
12013:20090417:140331 Send list of active checks to [x.x.x.x] failed: host [host.domain.com] not found

The agent log shows:
4647:20090417:140750 Unsucesfull response received from server


Any one have any idea what's the problem for this?

And should the server ip stated in the agent file be pointing to the zabbix server or the zabbix proxy?

The reason for failed active checks... in the zabbix_agentd.conf file, active checks are only sent to the first IP address on the "Server=" line. If you don't use active checks, then disregard that message. It is really just more of an info message than an error.

Now, for your config setups....

On your proxy:

zabbix_proxy.conf

Server=xxx.xxx.xxx.xxx  <-- the IP of your Zabbix server
Hostname=xxxxxxxxx   <-- this must be a unique name and match [U]exactly[/U] the name as you have it on your Zabbix server

If you make changes to the above, be sure to restart your proxy service

On your host:

zabbix_agentd.conf

Server=xxx.xxx.xxx.xxx,xxx.xxx.xxx.xxx  <-- Zabbix server [B]and[/B] Zabbix proxy IP's. Comma seperated.
LogFile=c:\zabbix\zabbix_agentd.log
Hostname=xxxxxxx   <-- Unique hostname, match exactly as entered on Zabbix server

If you make conf changes, restart the agent(s)

On the Zabbix GUI... Configuration --> Hosts --> Select "Proxies" from the dropdown and make sure that there is a value under the "Last seen (age)" column. Preferably not more than a few seconds old.

Finally, make sure that the host(s) are set to be monitored by the appropriate proxy

I tried this method and now i'm getting an error message in zabbix UI "Get value from agent failed: ZBX_TCP_READ() timed out"

Can you please help on this?

I did everything that you said and value under the "Last seen (age)" column is never more than a minute. But all my hosts which are monitored by proxy no retrieve any data.
Please help !

Hi Luke,

Some checks to do:

- Log files on ZABBIX Agent;
- Log files on ZABBIX Proxy;
- Log files on ZABBIX Server;

... logs are friends

Can you do a 'zabbbix_get -s <HOST AGENT> -k agent.ping' (from ZABBIX Proxy) ?

Hi Luciano,
Thanx for your anwser

The zabbix proxy log and zabbix server log return me the same error : Connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket 'var/run/mysqld/mysqld.sock' (2)

But I checked and the file mysqld.sock is in the good directory

I didn't see any other error in log files.

The command 'zabbbix_get -s <HOST AGENT> -k agent.ping' only return me a "1"

Thanx for help

Luke
