zabbix 监控TCP状态连接数
1、zabbix客户端，监控TCP状态脚本，并保存到的定路径。（/usr/local/zabbix-agent/shells）
# cat zabbix_linux_plugin.sh
#!/bin/bash
############################################################
# $Name: zabbix_linux_plugins.sh
# $Version: v1.0
# $Function: zabbix plugins
# $Create Date: 2014-08-10
# $Description: Monitor Linux Service Status
############################################################
tcp_status_fun(){
TCP_STAT=$1
ss -ant | awk 'NR>1 {++s[$1]} END {for(k in s) print k,s[k]}' > /tmp/netstat.tmp
TCP_STAT_VALUE=$(grep "$TCP_STAT" /tmp/netstat.tmp | cut -d ' ' -f2)
if [ -z $TCP_STAT_VALUE ];then
TCP_STAT_VALUE=0
fi
echo $TCP_STAT_VALUE
} main(){
case $1 in
tcp_status)
tcp_status_fun $2;
;;
*)
echo $"Usage: $0 {tcp_status key}"
esac
} main $1 $2 $3
2、在客户端中修改zabbix_agentd.conf配置文件(/usr/local/zabbix-agent/etc/zabbix_agentd.conf)
### Option: Include
# You may include individual files or all files in a directory in the configuration file.
# Installing Zabbix will create include directory in /usr/local/etc, unless modified during the compile time.
#
# Mandatory: no
# Default:
# Include= # Include=/usr/local/etc/zabbix_agentd.userparams.conf
# Include=/usr/local/etc/zabbix_agentd.conf.d/
Include=/usr/local/zabbix-agent/etc/zabbix_agentd.conf.d/*.conf # 启用Include，在zabbix_agentd.conf.d目录下的所有.conf文件被引用，
用来引用自定义key的配置文件。
3、在客户端中配置自定义KEY配置文件（/usr/local/zabbix-agent/etc/zabbix_agentd.conf.d/zabbix-linux-plugin.conf）
# cat zabbix-linux-plugin.conf
UserParameter=linux_status[*],/usr/local/zabbix-agent/shells/zabbix_linux_plugin.sh "$1" "$2" "$3"
4、以上配置完成，重启zabbix agent服务
# /etc/init.d/zabbix_agentd restart
5、tcp连接状态模板,这是配置好的模板，包括了TCP连接的11种状态，如果模板就需要一个一个的创建了。
# cat TCP_export_templates.3.0.xml
<?xml version="1.0" encoding="UTF-8"?>

6、zabbix server 端通过zabbix_get命令进行测试，验证是否可以正常获取TCP状态值
[root@linux-node1 ~]# zabbix_get -s 172.16.10.152 -k linux_status[tcp_status,ESTAB]
2
[root@linux-node1 ~]# zabbix_get -s 172.16.10.152 -k linux_status[tcp_status,LISTEN]
6
通过测试，我们可以看到，已经可以正确获取到值了，那么我们接下来，就可以在web页面将模板进行导入了。
7、zabbix web 监控页面导入tcp连接状态模板
模板（TCP_export_templates.3.0.xml）导入成功后，将模板链接到一台就机就可以了。
最后我们来看下TCP状态有没有监控上吧。
好了，数据也有了，图形展示也有了，监控TCP状态就介绍到这里了。
