二.安裝nginx與nginx-vts-exporter

這裡nginx是重新安裝 

解壓nginx-vts-exporter 這裡放在usr/local

unzip nginx-module-vts-master.zip      

解壓nginx  這裡放在usr/local 這裡注意nginx版本有要求否則會報錯 以下是nginx對應的版本

1. 解壓
2. tar -zxvf nginx-1.14.2.tar.gz      

把nginx-vts-exporter放到nginx路徑 

1. cd usr/local/nginx-1.14.2
2. ./configure --prefix=/usr/local/nginx --add-module=usr/local/nginx-module-vts-master/
3. 注意：注意prefix=/usr/local/nginx意思是安裝位置為/usr/local/nginx檔案夾
4. make install      

修改conf檔案

http {
    vhost_traffic_status_zone;
    vhost_traffic_status_filter_by_host on;
 
...
 
server {
 
    ...
 
    location /status {
        vhost_traffic_status_display;
        vhost_traffic_status_display_format html;
    }
}      

啟動

1. cd /usr/local/nginx/sbin
2. ./nginx      

通路

http://ip/status

出現以下顯示則安裝成功

三.安裝nginx-vts-exporter-0.9.1.linux-amd64.tar

這裡安裝包放在usr/local下

解壓

tar -zxvf nginx-vts-exporter-0.9.1.linux-amd64.tar      

1. cd /usr/local/nginx-vts-exporter-0.9.1.linux-amd64
2. nohup ./nginx-vts-exporter  -nginx.scrape_uri http://ip/status/format/json &      

輸入

http://ip:9913/metrics

如果出現以下證明完成

四.配置Prometheus

修改/usr/local/prometheus-2.17.1.linux-amd64/prometheus.yml

# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).
 
# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093
 
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"
 
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'
    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'nginx'
    static_configs:
      - targets: ['ip:9913']          

出現以下配置成功

五.配置Grafana

配置資料源 也就是prometheus位址 ip:9090

然後配置可視化界面模闆

選擇模闆導入上文的配置
