When troubleshooting issues on a Zabbix environment is crucial to evaluate the number of unsupported items over the time, as well the global number of configured hosts or items. For example a performance issue could be correlated with a spike of the number of unsupported item or with a mass host creation.

This information are provided by Internal items, but are missing in the default template.

Please add the following items and corresponding graphs/dashboard:

• zabbix[hosts] - Number of monitored hosts.    Integer.
• zabbix[items] - Number of enabled items (supported and not supported).    Integer.
• zabbix[items_unsupported] Number of not supported items.    Integer.
• zabbix[triggers] - Number of enabled triggers in Zabbix database, with all items enabled on enabled hosts.    Integer.
