Zabbix Server side through the communication with the Zabbix agent to obtain the client server data, the agent is divided into two versions, in the configuration host we can see one is the agent, the other is the agent (active).
Agent:zabbix Server begs the Zabbix agent for data.
Agent (Active): Zabbix agent submits data to Zabbix server.
Monitoring Items Keys List
The following table is a list of all the keys supported by the Zabbix agent, and the first thing to think about is whether the Zabbix agent already has the relevant key present, rather than writing the script to get the key.
Agent.hostnameReturns the monitored End name (string)
agent.pingDetects if the monitored side is alive (1: Running other: not running)-using function nodata () detectionwhether the client is running
