Application based on Zabbix built-in key

First, the built-in key description:

Zabbix has a lot of rich key built-in, so that when we add the Linux OS template, we have defined the key so that we can directly link the template to use.

Our side of the story lists some of the built-in keys, and then makes some simple notes: when we have built-in key to collect data, we'd better not write the custom key to collect: (I have seen an article of the CTO's write monitoring user login number, and W to monitor, not directly call the built-in key):

Second, the details can view the official documents:

Https://www.zabbix.com/documentation/3.0/manual/config/items/itemtypes/zabbix_agent#supported_item_keys

Third, built-in monitoring key list:
