zabbix的客户端

1、进入所有mysql本地服务器上的zabbix客户端创建脚本目录和文件
[root@i-ynodsrbz ~]# cd /usr/local/zabbix-2.4.2/
[root@i-ynodsrbz zabbix-2.4.2]# mkdir scripts
[root@i-ynodsrbz zabbix-2.4.2]# cd scripts/
[root@i-ynodsrbz scripts]# touch tcp_conn_status.sh
脚本内容如下：
#!/bin/bash
#this script is used to get tcp and udp connetion status
#tcp status
metric=$1
tmp_file=/tmp/tcp_status.txt
/bin/netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}' > $tmp_file

case $metric in
closed)
output=$(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
2、赋予脚本执行权限
[root@i-ynodsrbz scripts]# chmod +x tcp_conn_status.sh
3、在zabbix配置文件中添加脚本及其路径
[root@i-ynodsrbz scripts]# cd /usr/local/zabbix-2.4.2/etc/
[root@i-ynodsrbz etc]# vim zabbix_agentd.conf
在配置文件最后一行添加以下内容即可
UserParameter=tcp.status[*],/usr/local/zabbix-2.4.2/scripts/tcp_conn_status.sh $1
UnsafeUserParameters=1
4、重启zabbix客户端
[root@i-ynodsrbz ~]# pkill zabbix
[root@i-ynodsrbz ~]# /usr/local/zabbix-2.4.2/sbin/zabbix_agentd
5、zabbix服务端检测
[root@Zabbix-server ~]# /usr/local/zabbix-2.2.2/bin/zabbix_get -s 106.2.12.125 -p 10050 -k "tcp.status[listen]"
4
[root@Zabbix-server ~]#
5、web界面添加配置
