 First we need to create new user parameter for zabbix, I used `ct.memory.size`
 name similarly built-in `vm.memory.size` parameter, but with my own single line

     ct.cpu.load[percpu,avg5]

+Now add aliases to make the new/correct data available under the standard item names:

+    Alias=vm.memory.size:ct.memory.size
+    Alias=system.swap.size:ct.swap.size

 Don’t forget to restart `zabbix-agent.service` after
 
 Ok, now we can check is our parameter working from zabbix server:
 
     $ zabbix_get -s <container_ip> -k ct.memory.size[available]

-Ok it’s working.

-Now let’s configure zabbix for use them. In Zabbix Interface:
-
-Go Configuration → Templtes
+This new value should now also be available under the standard name:
 
-* Make full copy “Template OS Linux” to “Template Linux Container”
-* Open “Template Linux Container” → Items
-* Replace all `vm.memory.size` items to `ct.memory.size`.
-* Replace all `system.swap.size` items to `ct.swap.size`:<br> You also need to
-remove commas in key filed here. Example:<br> replace `system.swap.size[,free]`
-to `ct.swap.size[free]`
-* Replace all `system.cpu.load[percpu,*]` items to `ct.cpu.load[percpu,*]`.
-
-Or just download and import [my zabbix template](https://github.com/kvaps/zabbix-linux-container-template/blob/master/zbx_linux_container_template.xml).
-
-Next, go to the Configuration → Hosts
+    $ zabbix_get -s <container_ip> -k vm.memory.size[available]
+    1709940736
 
-* Unlink and clear “Template OS Linux” from your hosts
-* Attach “Template Linux Container”
+Ok it’s working.
