zabbix监控tcp的11种状态

监控tcp的11种状态

• 通过shell脚本，传递参数，根据参数返回结果

  [root@zabbix_agent zabbix]# pwd
  /etc/zabbix
  [root@zabbix_agent zabbix]# mkdir shell && cd shell
  
  [root@zabbix_agent shell]# vim tcp_status.sh
  #!/bin/bash
  metric=$1
  tmp_file=/tmp/tcp_status.txt
  /usr/bin/netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}' > $tmp_file

  esac
  
  
  [root@zabbix_agent tmp]# systemctl restart zabbix-agent   #重启zabbix-agent

• 在server端通过zabbix_get工具测试

  [root@zabbix_server ~]# zabbix_get -s 192.168.1.130 -k tcp.status[]
  Usage: sh  /etc/zabbix/shell/tcp_status.sh [closed|closing|closewait|synrecv|synsent|finwait1|finwait2|listen|established|lastack|timewait]
  [root@zabbix_server ~]# zabbix_get -s 192.168.1.130 -k tcp.status[timewait]
