For this recipe, make sure that you are a Zabbix administrator and that you have your agent configured on the Zabbix server. Also make sure that the template Template App Zabbix Server is linked with your Zabbix host.

From the menu, go to Monitoring | Latest data and select the Zabbix server as host to see. Select Zabbix server from the item list to get an overview of the data of all items:

Here we have an easy overview of how much our pollers are busy or idle. Remember that in our Zabbix 2.4, we have graphs automatically generated in Latest data, so we can click on those graphs and see easy if, for example, at a certain time pollers were not enough available.

The data that we see here is based on the internal items, more specifically this one: zabbix[process,<type>,<mode>,<state>].

With this item, we first have to choose a process type that we want to monitor. We select a type from a long list.. Here we specify what we want to monitor, be it a trapper, ICMP pinger, housekeeper, or anything else.

Next we specify the mode. The mode will tell us what data we want to see from our process, for example .avg, max, min, and so on.

And as last option, we specify the state from our process. Here we will specify if we want to monitor the busy or idle state from our process.

For a full list of types that can be used, check the Zabbix documentation and look for zabbix[process,<type>,<mode>,<state>].
