After a routine production environment build Nginx cluster, we need to continue in-depth study is the daily monitoring of Nginx.
How Nginx monitor? I believe Baidu can be found: nginx-status
By Nginx-status, real-time access to the monitoring data Nginx, and how existing monitoring systems integration? A good solution:
INX + Telegraf + Influxdb + Grafana
I.e., monitoring the timing Telegraf collected by monitoring status of Nginx widget, stored in the database Influxdb sequence, and then to show by Grafana.
A, Nginx nginx-status function is enabled
Nginx source compiler installed, you need to add corresponding module at compile time
./configure --with-http_stub_status_module
Use ./configure --help to see more support module. Then you can compile and install.
If you are directly installed apt-get install nginx, then use the command to see if support stub_status this module.
The following command: nginx -V to see if there --with-http_stub_status_module this module.
Modify Nginx configuration file: Increase in Server section:
location /nginx-status {
allow 127.0.0.1; // allowed IP
deny all;
stub_status on;
access_log off;}
Reload restart Nginx, see Nginx-Status
Output Description information:
active connections - the number of active connections server accepts handled requests - handled a total of 11,989 connections, successfully created 11989 handshake, handled a total of 11,991 requests reading — 读取客户端的连接数 writing — 响应数据到客户端的数量 waiting — 开启 keep-alive 的情况下,这个值等于 active – (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.
二、Telegraf安装配置Nginx监控
关于Telegraf的安装，请参考官方介绍
https://www.influxdata.com/time-series-platform/telegraf/
wget https://dl.influxdata.com/telegraf/releases/telegraf-1.4.3-1.x86_64.rpmsudo yum localinstall telegraf-1.4.3-1.x86_64.rpm
然后，在配置文件teldgraf.conf中配置Influxdb连接
增加对Nginx的监控
配置完成，重启telegraf服务即可。
三、Grafana集成Nginx监控
Grafana中支持Influxdb数据源，配置上上个步骤的Influxdb数据源之后，我们定制Nginx监控图表：
数据源：Influxdb
FROM：nginx
SELECT：field（accepts）
展现效果：
以上我们通过Nginx+Telegraf+Influxb+Grafana，实现了Nginx的监控,非常方便。
你们在日常实际生产环境对Nginx的状态监控使用的是何种技术？
