zabbix监控TCP连接数方法

1、zabbix server的版本为3.4.9

2、自定义监控项tcp.status

3、cat /etc/zabbix/scripts/tcp_conn_status.sh#!/bin/bash#this script is used to get tcp and udp con荏鱿胫协netion status#tcp statusmetric=$1tmp_file=/tmp/tcp_status.txt/bin/netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}' > $tmp_filecase $metric in closed) output=$(awk '/CLOSED/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; listen) output=$(awk '/LISTEN/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; synrecv) output=$(awk '/SYN_RECV/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; synsent) output=$(awk '/SYN_SENT/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; established) output=$(awk '/ESTABLISHED/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; timewait) output=$(awk '/TIME_WAIT/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; closing) output=$(awk '/CLOSING/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; closewait) output=$(awk '/CLOSE_WAIT/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; lastack) output=$(awk '/LAST_ACK/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; finwait1) output=$(awk '/FIN_WAIT1/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; finwait2) output=$(awk '/FIN_WAIT2/{print $2}' $tmp_file) if [ "$output" == "" ];then echo 0 else echo $output fi ;; *) echo -e "\e[033mUsage: sh $0 [closed|closing|closewait|synrecv|synsent|finwait1|finwait2|listen|established|lastack|timewait]\e[0m" esac

4、zabbix web页面创建监控项

5、最新数据中已经有TCP的连接信息了

6、点图形可以看到趋势

7、还可以创建触发器
