Zabbix 监控 Nginx

Zabbix监控Nginx

首先，大家如果看到有什么不懂的地方，欢迎吐槽！！！
我会在当天或者第二天及时回复，并且改进~~

首先zabbix监控nginx 是根据nginx的Stub Status模块,抓取Status模块所提供的数据。
如果想启用Stub Status模块，在编译nginx的时候要加上参数
--with-http_stub_status_module 

例如：
./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

在Nginx配置档中添加：
     location /nginx_status {
                stub_status on;
                access_log   off;
                }

• nginx_status_key

vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/nginx_status_key

UserParameter=nginx.accepts,/usr/local/zabbix/shell/nginx_status.sh accepts
UserParameter=nginx.handled,/usr/local/zabbix/shell/nginx_status.sh handled
UserParameter=nginx.requests,/usr/local/zabbix/shell/nginx_status.sh requests
UserParameter=nginx.connections.active,/usr/local/zabbix/shell/nginx_status.sh active
UserParameter=nginx.connections.reading,/usr/local/zabbix/shell/nginx_status.sh reading
UserParameter=nginx.connections.writing,/usr/local/zabbix/shell/nginx_status.sh writing
UserParameter=nginx.connections.waiting,/usr/local/zabbix/shell/nginx_status.sh waiting

• nginx_status.sh

vim /usr/local/zabbix/shell/nginx_status.sh

#!/bin/bash
# Script to fetch nginx statuses for tribily monitoring systems
# License: GPLv4
# Set Variables
BKUP_DATE=`/bin/date +%Y%m%d`
LOG="/usr/local/zabbix/logs/nginx_status.log"
HOST="192.168.0.217"        #HOST非常重要，确保CURL能访问到这个IP地址的Status
PORT="80" 

# Functions to return nginx stats
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}'
    }
# Run the requested function
$1 

• nginx.accepts
• nginx.handled
• nginx.requests

我在这边做一个示例：
模版中添加一个nginx.accepts的item

Name                nginx.accepts
Type                Zabbix agent
Key                 nginx.accepts
Type of information Numeric (unsigned)
Data Type           Decimal
Units               空
Store value         Detal (speed per second)
Show  value         As is 

(2)、而后四个item Store value是不变的

• nginx.connections.active
• nginx.connections.reading
• nginx.connections.writing
• nginx.connections.waiting

Name                nginx.connections.active
Type                Zabbix agent
Key                 nginx.accepts
Type of information Numeric (unsigned)
Data Type           Decimal
Units               空
Store value         As is
Show  value         As is 

监控Nginx(nginx.accepts、nginx.handled、nginx.requests)
监控Nginx(nginx.connections.active、nginx.connections.reading、nginx.connections.writing、nginx.connections.waiting)

图像1：暂且取名为 Nginx_Interactive
