Zabbix’s control center collects data and writes it into the database.
A process on the monitored server responsible for interacting with zabbix server

Specific monitoring indicators
A combination of logical rules
The action that is triggered when the trigger meets a certain value
Configure host /item/trigger
There are mainly three parts here, action, conditions and operations.
Item of trapper type listens to 10051 by default
Zabbix data transfer protocol
1.<HEADER>:ZBXDx01, 5 bytes in total
2.<DATALEN >: the length of the data transferred by this connection is 8 bytes in total. for example, if the length is 1, then here is 01/00/00/00/00/00/00/00, i.e. 8 bytes in hexadecimal and 64 digits.
In order to limit memory consumption, the maximum data transferred per connection cannot exceed 64MB.
Passive and active modes
Server or proxy actively requests data from zabbix agent, and then agent sends the data back to server or proxy.
Agent actively sends the data to zabbix server. First, it will pull the list of item to be sent from the server, then it will get the data according to the list and send it to the server.
Screen is a set of graph, examples of which are as follows:
If screen is created, it will be created under monitoring–>screens. for trapper type, select simple graph.
