zabbix监控tcp连接数

系统：centos6.5
zabbix：2.4.4
首先创建脚本




系统：centos6.5
zabbix：2.4.4
首先创建脚本

# vim /usr/local/scripts/tcp_connections.sh
#!/bin/bash

stat() {
      netstat -an | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S}'
      }

case $1 in
      TIME_WAIT)
      stat |grep 'TIME_WAIT' |awk '{print $2}'
      ;;
      CLOSE_WAIT)
      stat | grep 'CLOSE_WAIT' |awk '{print $2}'
      ;;
      FIN_WAIT1)
      stat | grep 'FIN_WAIT1' |awk '{print $2}'
      ;;
      ESTABLISHED)
      stat | grep 'ESTABLISHED' |awk '{print $2}'
      ;;
      SYN_RECV)
      stat |grep 'SYN_RECV' |awk '{print $2}'
      ;;
      LAST_ACK)
      stat |grep 'LAST_ACK' |awk '{print $2}'
      ;;
      LISTEN)
      stat |grep 'LISTEN' |awk '{print $2}'
      ;;
      *)
      echo "Usage: TIME_WAIT CLOSE_WAIT FIN_WAIT1 ESTABLISHED SYN_RECV LAST_ACK LISTEN"
      ;;
esac

# vim /usr/local/scripts/tcp_connections.sh
#!/bin/bash

stat() {
      netstat -an | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S}'
      }

case $1 in
      TIME_WAIT)
      stat |grep 'TIME_WAIT' |awk '{print $2}'
      ;;
      CLOSE_WAIT)
      stat | grep 'CLOSE_WAIT' |awk '{print $2}'
      ;;
      FIN_WAIT1)
      stat | grep 'FIN_WAIT1' |awk '{print $2}'
      ;;
      ESTABLISHED)
      stat | grep 'ESTABLISHED' |awk '{print $2}'
      ;;
      SYN_RECV)
      stat |grep 'SYN_RECV' |awk '{print $2}'
      ;;
      LAST_ACK)
      stat |grep 'LAST_ACK' |awk '{print $2}'
      ;;
      LISTEN)
      stat |grep 'LISTEN' |awk '{print $2}'
      ;;
      *)
      echo "Usage: TIME_WAIT CLOSE_WAIT FIN_WAIT1 ESTABLISHED SYN_RECV LAST_ACK LISTEN"
      ;;
esac

测试脚本是否可用

# chmod +x tcp_connections.sh
# ./tcp_connections.sh ESTABLISHED
125

# chmod +x tcp_connections.sh
# ./tcp_connections.sh ESTABLISHED
125

编辑zabbix_agentd配置

# vim /usr/local/etc/zabbix_agentd.conf.d/monitor_tcp_connections.conf
UserParameter=tcp.time_wait,/usr/local/scripts/tcp_connections.sh TIME_WAIT
UserParameter=tcp.close_wait,/usr/local/scripts/tcp_connections.sh CLOSE_WAIT
UserParameter=tcp.fin_wait1,/usr/local/scripts/tcp_connections.sh FIN_WAIT1
UserParameter=tcp.established,/usr/local/scripts/tcp_connections.sh ESTABLISHED
UserParameter=tcp.syn_recv,/usr/local/scripts/tcp_connections.sh SYN_RECV
UserParameter=tcp.last_ack,/usr/local/scripts/tcp_connections.sh LAST_ACK
UserParameter=tcp.listen,/usr/local/scripts/tcp_connections.sh LISTEN

# vim /usr/local/etc/zabbix_agentd.conf.d/monitor_tcp_connections.conf
UserParameter=tcp.time_wait,/usr/local/scripts/tcp_connections.sh TIME_WAIT
UserParameter=tcp.close_wait,/usr/local/scripts/tcp_connections.sh CLOSE_WAIT
UserParameter=tcp.fin_wait1,/usr/local/scripts/tcp_connections.sh FIN_WAIT1
UserParameter=tcp.established,/usr/local/scripts/tcp_connections.sh ESTABLISHED
UserParameter=tcp.syn_recv,/usr/local/scripts/tcp_connections.sh SYN_RECV
UserParameter=tcp.last_ack,/usr/local/scripts/tcp_connections.sh LAST_ACK
UserParameter=tcp.listen,/usr/local/scripts/tcp_connections.sh LISTEN

重启服务

# /etc/init.d/zabbix_agentd restart
Shutting down zabbix_agentd:                               [确定]
Starting zabbix_agentd:                                    [确定]

# /etc/init.d/zabbix_agentd restart
Shutting down zabbix_agentd:                               [确定]
Starting zabbix_agentd:                                    [确定]

测试监控是否有数据

# zabbix_get -s localhost -k tcp.established
126

# zabbix_get -s localhost -k tcp.established
126

然后在web里创建模版，方便以后多台添加
填写模版名称
创建监控项
创建图形
模版创建完成后，要关联到监控主机
点击主机，选择模版

等一会儿数据图形就会出现
