Nginx 監(jiān)控模塊(vts模塊)

監(jiān)控Nginx主要用到以下三個模塊：
1、nginx-module-vts：Nginx virtual host traffic status module，Nginx的監(jiān)控模塊，能夠提供JSON格式的數(shù)據產出。
2、nginx-vts-exporter：Simple server that scrapes Nginx vts stats and exports them via HTTP for Prometheus consumption。主要用于收集Nginx的監(jiān)控數(shù)據，并給Prometheus提供監(jiān)控接口，默認端口號9913。
3、Prometheus：監(jiān)控Nginx-vts-exporter提供的Nginx數(shù)據，并存儲在時序數(shù)據庫中，可以使用PromQL對時序數(shù)據進行查詢和聚合。

1、上傳nginx-module-vts-master軟件包并解壓

unzip nginx-module-vts-master.zip 解壓

2、安裝Nginx依賴環(huán)境

yum -y install gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

3、優(yōu)化路徑及編譯安裝nginx

 make && make install

優(yōu)化管理

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin 

檢查開啟的模塊

nginx -v? 檢查 nginx版本nginx -V

watch -n 1 nginx 觀察nginx狀態(tài)

4、備份nginx的備份文件

5、修改nginx的配置文件

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

進去后再http{ } 中添加如下內容

vhost_traffic_status_zone;?? ??? ??? ?#流量狀態(tài)監(jiān)控?log_format main "{ "@timestamp": "$time_local", """@fields": { """uri":"$request_uri","""url":"$uri","""upstream_addr":"$upstream_addr","""remote_addr": "$remote_addr", """remote_user": "$remote_user", """body_bytes_sent": "$body_bytes_sent", """host":"$host","""server_addr":"$server_addr","""request_time": "$request_time", """request_time":"$request_time","""status":"$status","""request": "$request", """request_method": "$request_method", """size":$body_bytes_sent,"""upstream_time":"$upstream_response_time""""http_referrer": "$http_referer", """body_bytes_sent":"$body_bytes_sent", """http_x_forwarded_for": "$http_x_forwarded_for", """http_user_agent": "$http_user_agent" } }";

在server中80端口添加

 location /status {<!--{C}%3C!%2D%2D%20%2D%2D%3E-->    vhost_traffic_status_display;    vhost_traffic_status_display_format html;}

在虛擬機中測試 192.168.100.10/status

6、監(jiān)控模塊各字段信
