Monitoring Nginx dengan Grafana Dashboard

sudo apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring
 

 curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor     | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
 

gpg --dry-run --quiet --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg

echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
    | sudo tee /etc/apt/preferences.d/99nginx

 

sudo apt update && sudo apt upgrade

 

mkdir software

 

sudo apt-get source nginx 

sudo apt-get build-dep nginx

cd nginx/

sudo dpkg -i  lib*.deb

sudo dpkg -i nginx-core_1.18.0-6.1_amd64.deb nginx-common_1.18.0-6.1_all.deb nginx_1.18.0-6.1_all.deb

 

git clone https://github.com/vozlt/nginx-module-vts.git

 

cd /usr/local/src/nginx-1.18.0/

sudo ./configure --with-compat --add-dynamic-module=/home/cendikia/software/nginx-module-vts/

sudo make modules

 

sudo cp objs/ngx_http_vhost_traffic_status_module.so /etc/nginx/modules/
 

Untuk prometheus, kita tidak perlu menggunakan export, karena nginx-module-vts sudah mendukung format untuk prometheus, yg dapat diakses pada alamat :
http://localhost/status/format/prometheus

Konfigurasi prometheus

 /etc/prometheus/prometheus.yml 

scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s
    scrape_timeout: 5s

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ['localhost:9090']

  - job_name: node
    # If prometheus-node-exporter is installed, grab stats about the local
    # machine by default.
    static_configs:
      - targets: ['localhost:9100']

  - job_name: 'nginx-vts'
    metrics_path: '/status/format/prometheus'
    static_configs:
      - targets: ['localhost']
