zabbix3.0对tcp连接数和状态的监控优化
zabbix3.0对tcp连接数及状态的监控优化
之前对tcp的监控采用netstat命令，发现在服务器繁忙的时候效果不理想，这个命令占用大量的cpu有时候高达90%以上，可能会导致业务的不稳定，所以改用ss命令对脚本进行优化
在需要被监控的zabbix-agent端添加脚本编写
创建文件夹
mkdir -p /usr/local/zabbix-agent/scripts/
mkdir -p /etc/zabbix/zabbix_agentd.d/
vim /usr/local/zabbix-agent/scripts/tcp_status_ss.sh
#!/bin/bash
#scripts for tcp status
function SYNRECV {
/usr/sbin/ss -ant | awk '{++s[$1]} END {for(k in s) print k,s[k]}' | grep 'SYN-RECV' | awk '{print $2}'
}
function ESTAB {
/usr/sbin/ss -ant | awk '{++s[$1]} END {for(k in s) print k,s[k]}' | grep 'ESTAB' | awk '{print $2}'
}
function FINWAIT1 {
/usr/sbin/ss -ant | awk '{++s[$1]} END {for(k in s) print k,s[k]}' | grep 'FIN-WAIT-1' | awk '{print $2}'
}
function FINWAIT2 {
/usr/sbin/ss -ant | awk '{++s[$1]} END {for(k in s) print k,s[k]}' | grep 'FIN-WAIT-2' | awk '{print $2}'
}
function TIMEWAIT {
/usr/sbin/ss -ant | awk '{++s[$1]} END {for(k in s) print k,s[k]}' | grep 'TIME-WAIT' | awk '{print $2}'
}
function LASTACK {
/usr/sbin/ss -ant | awk '{++s[$1]} END {for(k in s) print k,s[k]}' | grep 'LAST-ACK' | awk '{print $2}'
}
function LISTEN {
/usr/sbin/ss -ant | awk '{++s[$1]} END {for(k in s) print k,s[k]}' | grep 'LISTEN' | awk '{print $2}'
}
$1
或者
#!/bin/bash
#scripts for tcp status
function SYNRECV {
/usr/sbin/ss -s | grep 'synrecv' | awk '{print $2}'
}
function ESTAB {
/usr/sbin/ss -s | grep 'estab' | awk '{print $2}'
}
function FINWAIT1 {
/usr/sbin/ss -o | grep 'FIN-WAIT-1'|wc -l
}
function FINWAIT2 {
/usr/sbin/ss -ant| grep 'FIN-WAIT-2' | wc -l
}
function TIMEWAIT {
/usr/sbin/ss -ant | grep 'TIME-WAIT' | wc -l
}
function LASTACK {
/usr/sbin/ss -ant | grep 'LAST-ACK' | wc -l
}
function LISTEN {
/usr/sbin/ss -ant | grep 'LISTEN' | wc -l
}
$
赋予脚本执行权限
chmod +x /usr/local/zabbix-agent/scripts/tcp_status_ss.sh
二、填写key值：当然大家在加入key值之后最好再服务器上面去执行看有没有返回值：
vim /etc/zabbix/zabbix_agentd.d/tcp_status_ss.conf
#monitor tcp
UserParameter=tcp[*],/usr/local/zabbix-agent/scripts/tcp_status_ss.sh $1
重启agent
service zabbix-agent restart
zabbix-server服务端测试
zabbix_get -s 192.168.3.18 -p 10050 -k "tcp[LISTEN]"
zabbix_get -s 192.168.3.18 -p 20050 -k "tcp[LISTEN]"

zabbix web端配置：
登录Zabbix3.0 的web界面，一次选择 Configuration > Templates,在主界面的右上角有个 Import 按钮，用来导入模板
