按照zabbix客户端及自定义监控nginx连接状态
一、下载客户端按照包，这里用rpm包安装1
# rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-agent-3.0.4-1.el7.x86_64.rpm
修改客户端配置文件
1
2
Server=127.0.0.1
ServerActive=127.0.0.1
改为zabbix server实际的IP地址(比如zabbix server的IP地址为10.0.0.100)
1
2
Server=10.0.0.100
ServerActive=10.0.0.100
重启zabbix 客户端
1
# systemctl restart zabbix-agent
二、自定义脚本监控nginx连接状态:

#!/bin/bash
HOST=localhost
PORT="9999"
function active {
/usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
/usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
/usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
/usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
/usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
/usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
/usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
$1
将脚本存放与脚本目录，注意该目录根据自己情况定义，我这里用rpm 按照zabbix-agent客户端，所以直接放在/etc/zabbix/script目录下
1
2
3
# ll nginx-status.sh
-rwx------ 1 root root 947 Mar 22 10:49 nginx-status.sh
#
不要忘了给脚本执行权限

# chmod +x nginx-status.sh
#
# ll nginx-status.sh
-rwxr-xr-x 1 root root 947 Mar 22 10:49 nginx-status.sh
