Zabbix系列之五——监控TCP端口

监控端口的几个主要Keys：

net.tcp.listen[port]	Checks if this port is in LISTEN state. 0 - it is not, 1 - it is in LISTEN state. 监控TCP端口是否监听
net.tcp.port[<ip>,port]	Check, if it is possible to make TCP connection to the port number. 0 - cannot connect, 1 - can connect. IP address is optional. If ip is missing, 127.0.0.1 is used. Example: net.tcp.port[,80] 检查TCP端口是否可以正常连接。
net.tcp.service[service,<ip>,<port>]	Check if service is available. 0 - service is down, 1 - service is running. If ip is missing 127.0.0.1 is used. If port number is missing, default service port is used. Example: net.tcp.service[ftp,,45]. 检查服务是否可用，FTP服务可直接使用FTP模板
net.tcp.service.perf[service,<ip>,<port>]	Check performance of service "service". 0 - service is down, sec - number of seconds spent on connection to the service. If ip is missing 127.0.0.1 is used. If port number is missing, default service port is used. 监控服务（端口）连接性能
net.udp.listen[port]	Checks if this port is in LISTEN state. 0 - it is not, 1 - it is in LISTEN state. 监控UDP端口是否监听（不支持windows）

说明：Zabbix自带单独服务检测模板，如Template App FTP Service，就是使用的ket.tcp.service[ftp]这个KEY来监控的。

模板如下，可根据需求修改端口及触发器名称：
