zabbix监控nginx

简介:

一 nginx配置

(1)在nginx配置文件中,添加status配置:

7
location /nginx-status {
           stub_status on;
           access_log  off;
           allow 127.0.0.1;
           allow 192.168.1.0/24;
           deny all;
}

注:这是用于查看nginx的运行参数

然后访问:http://192.168.1.30/nginx-status

输出如下格式的数据:

1
2
3
4
Active connections: 4
server accepts handled requests
7 7 10
Reading: 0 Writing: 1 Waiting: 3

注:关于上面参数的详细说明:

  • Active connections    对后端发起的活动连接数;

  • server accepts 7    nginx 总共处理了7个连接;

  • handled    成功创建了7次握手;

  • requests    总共处理了10请求。

  • Reading    nginx读取客户端的header数;

  • Writing    nginx 返回给客户端的header数;

  • Waiting    nginx 请求处理完成,正在等待下一请求指令的连接

二 zabbix客户端配置

(1)编写客户端脚本nginx_status.sh

1
[root@localhost scripts] # vim /usr/local/zabbix/scripts/nginx_status.sh

其内容如下:

#!/bin/bash
# Description:zabbix监控nginx性能以及进程状态
# Note:此脚本需要配置在被监控端,否则ping检测将会得到不符合预期的结果
 
HOST= "127.0.0.1"
PORT= "80"
 
# 检测nginx进程是否存在
function  ping  {
     /sbin/pidof  nginx |  wc  -l 
}
# 检测nginx性能
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}'
}
# 执行function
$1

给脚本添加执行权限:

1
[root@localhost scripts] # chmod a+x /usr/local/zabbix/scripts/nginx_status.sh

(2)修改zabbix_agentd.conf并重启zabbix_agentd:

1
[root@localhost zabbix] # vim /usr/local/zabbix/etc/zabbix_agentd.conf

添加:

1
UserParameter=nginx.status[*],/usr/local/zabbix/scripts/nginx_status.sh $1

重启zabbix_agentd:

1
[root@localhost zabbix] # service zabbix_agentd restart

三 zabbix_server测试获取数据以及配置web界面

(1)在zabbix server使用zabbix_get测试获取数据:

1
[root@localhost ~] # /usr/local/zabbix/bin/zabbix_get -s 192.168.1.30 -k 'nginx.status[accepts]'

输出如下:

1
 

如果有数据输出,则说明上面的配置已经成功了,接下来就是配置web界面了

(2)web界面配置:

由于上面已经可以通过zabbix_get获取到nginx的一些状态参数了,因此在配置web界面时就可以通过新建模板,并新建一些参数对应的监控项,以及添加显示“图形”等。具体实现思路可以参考我以前写过的这篇文章:https://www.zifangsky.cn/582.html

如果嫌麻烦的话也可以直接导入现成的模板:

模板文件Template App NGINX.xml:
