Server and proxy internal items

In addition to the Zabbix queues, the internal items allow us to identify the behavior of important points of Zabbix. But a review of the internal metrics can't be thought of alone. The value of a metric may be altered due to another metric that is not being evaluated. Correlation of metrics is something that cannot fail to occur.

In this section, we will talk about the major internal items that are directly related to Zabbix's performance. We will also explore the possible values and the likely consequences and impact of changes in these values.

This table will help you learn more about each of these metrics:

Internal key	Details
zabbix[items] zabbix[items_unsupported]	These two items help us keep Zabbix's unsupported items clean, which are great villains with respect to performance. The trick is to have a trigger that calculates the percentage of unsupported items and generate alerts if this value is exceeded. Usually, we work with a 2 percent limit. Thus...
