Internal checks
We have already seen that Zabbix is great at monitoring hosts but Zabbix is not limited to just collecting information from other hosts. The Zabbix internal items are items Zabbix can monitor to give us some insights on what's going on under the hood. Monitoring the internals is probably not your first task when you start your setup. Zabbix is configured from the start to work well but when your installation grows you will see the need to tweak/optimize some settings.
Getting ready
What do we need for this topic? You need to have your Zabbix server up and running. Internal items are internal checks, so we don't need an agent. Zabbix is perfectly capable to monitor its internals without the help of an agent. You only need to make sure that you have super administration rights.
How to do it …
On your host or in a template, go to items and click Create item to add a new item.
In the Name field add a name for the item.
For Type, we select
Zabbix internal.For the Key, we select
zabbix...
