Zabbix Proxy

[clarkritchie]

I am doing a proof of concept with Zabbix. The site is up and running and when I'm on a VPN I can monitor hosts in my network. Great! Now I am trying to get zabbix-proxy going.

zabbix-proxy is on an Ubuntu 12.04 box in the core of my network. 10051 is mapped from the firewall to that host. SELinux is disabled.

It seems like the server and proxy are communicating, but when the VPN is disconnected I cannot get back any data from items in that network, nor does ping/traceroute work (via the Zabbix application -- ping/traceroute from the Ubuntu box works fine).

On the server's log I see:
7507:20130824:133321.408 Sending configuration data to proxy 'inow'. Datalen 5510


On the proxy's log I see:
15796:20130824:233319.456 Received configuration data from server. Datalen 5510
15796:20130824:233319.457 Invalid field name "name"

Any idea what that Invalid field name "name" error may be? The Hostname directive in zabbix_proxy.conf matches what I setup on the Zabbix server. The Sending configuration/Received configuration makes me think the server is talking to the proxy OK.

Any suggestions? Thank you so much.

Might be easier if you post you full zabbix_proxy.conf file here.

It seems like the server and proxy are communicating...

You can check proxy availability in DM section - https://www.zabbix.com/documentation...inistration/dm (just for information).

I don't see anything odd in your proxy conf file.
One of the hosts you have checking in to that proxy uses an IP address as it's name. Is that intentional? I don't know that it would be an issue. Maybe worth looking at though. Are you getting data from these 2 hosts when your VPN is connected? You only have 3 items for them coming in.

Well, I was lazy. Or I am lazy because I did not compile from source. Version mismatch. Similar to this thread.

I guess the zabbix-proxy that's out there in the Ubuntu universe is old. Added a newer repo and all seems good.

root@beaker:/etc/zabbix# zabbix_server -V
Zabbix server v2.0.7 (revision 37436) (31 July 2013)

Was:

root@monitor:/usr/sbin# ./zabbix_proxy -V
Zabbix Proxy v1.8.11 (revision 26205) (20 March 2012)

Now:


root@monitor:/usr/sbin# ./zabbix_proxy -V
Zabbix proxy v2.0.4 (revision 31984) (08 December 2012)
Compilation time: Feb 8 2013 18:32:14
