In this recipe, we will show you how to set up your passive proxy. We will also show you the most important parameters that you need to configure when setting up a passive proxy.
What we need for this recipe is of course, our Zabbix server with super administrator rights. We need an extra machine to install our proxy. You also have to set up your proxy as we showed you in the previous recipe, Installing a proxy.
- Install the Zabbix proxy just as we have seen in the recipe, Installing a proxy.
- In the
zabbix_proxy.conffile, we need to change the optionProxy Mode:Proxy Mode = 1
- Change the
ProxyConfigFrequency = 3600option in thezabbix_server.conffile to a value that suits this option. This will influence how many times the Zabbix server will send the configuration to the proxy. - Change the
ProxyDataFrequency = 1option in thezabbix_server.conffile to a value that suits you. This will tell the Zabbix server how many times it needs to fetch history data from the proxy. - In the
zabbix_server.conffile, alter the optionStartProxyPollers=1to at least the number of proxies in your network. - Restart both Zabbix server and proxy to update the configuration.
service zabbix-server restartand for the proxyservice zabbix-proxy restart.- Go to the Zabbix web frontend to Administration | Proxies and create a proxy.
- Add the Proxy name.
- Select
Passivefor Proxy mode. - Add the correct Interface (IP or DNS preferable IP).
- Save the configuration.
When we work with a passive proxy, the proxy will just work like a passive client. The proxy will wait for the server to initiate a connection to fetch all the data from the proxy.
A passive proxy is perfect to use in a DMZ zone where you don't just want your severs to communicate with your LAN. This way the Zabbix server will initiate the connection and fetch all data from the proxy over port 10051.
