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=$1ss -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 ];thenTCP_STAT_VALUE=0

fiecho $TCP_STAT_VALUE}main(){case $1 intcp_status)tcp_status_fun $2;;;*)echo $”Usage: $0 {tcp_status key}”

esac}main $1 $2 $32、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 restart5、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 3.0

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
