1. Configuration ——> Hosts ——> Great Items (Figure 1)
图一Type detects data in the following ways:
Second, the definition of the key value: define what we use to collect some data information
Host interface: get information from which device, what is the port number, defined when creating the host.
Type of information: define the types of data we collect information
floating point: the decimal character: no more than 225, too much will automatically intercept text: character collected some more
Units: Unit is 1MB = 1024KB 1024MB = 1G
Update interval The: every acquisition The time between two data can be flexibly defined.
History storage period: historical data retention time; refers to the storage time of the acquired data in the database.
Trend storage period: trend storage time; data calculated based on history.
Descrition: Description and supplement to Item.
Preprocessing: Customize data multiples before data storage; also called preprocessing.
3. Other related knowledge of Item:
4. Key value:
key[param1,param2]: It means that the key has two parameters, param1 and param1. If you take the parameters, you need to enter $1,$2.
key["param1,param2"]: It means that the key has one Parameters, param1 and param2,
key[param1[param2]: the parameter representing the key is invalid.
key['param1,param2']: represents that the key has two parameters,'param1 and param2'
5. Batch update: 
0 means off state, 1 means on state
6. Value mapping
configuration——>Host——>Monitoring item——>SSH server status——>Display value mapping——>Create value mapping (Figure 1)——>Changed result (Figure 2)

图二Seven, there are two types of custom interval time:
1. Flexible: refers to the time period of data acquisition, but here it will not change the zabbix scheduling mode.
2. Scheduling:
md: the day of the month month day
wd: the day of the week week day
h: hours
m: minutes
s: seconds
zabbix active mode does not support, only passive mode support, because the active mode is initiated independently, flexible scheduling is nothing value.
wd3m13: schedule on the thirteenth minute of every Wednesday every hour
md13m13: schedule on the 13th minute of every hour on the 13th day of every month.
