This article mainly introduces "how to monitor nginx based on prometheus". In daily operation, I believe many people have doubts about how to monitor nginx based on prometheus. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how to monitor nginx based on prometheus". Next, please follow the editor to study!

Installation preparation

Nginx server: 172.22.3.164

Prometheus and grafnana are installed on the prometheus host

You can choose two exporter to monitor nginx based on prometheus. One is to obtain the built-in indicators in nginx-status through nginx_exporter. Nginx itself provides status information, which is relatively simple, and there are fewer corresponding metrics in promethues. The other is that more metrics can be monitored through nginx-vts-exporter, but nginx-vts-exporter relies on adding nginx-module-vts modules when compiling nginx. Vts provides information to access the status of the virtual host, including the current status of server,upstream and cache, and obviously the metrics will be richer. This practice mainly introduces the use of nginx-vts-exporter to monitor nginx based on prometheus.

Modify nginx.conf

Http {vhost_traffic_status_zone; vhost_traffic_status_filter_by_host on; server {listen 10011; server_name localhost; # vhost_traffic_status off; location / nginx_status {vhost_traffic_status_display; vhost_traffic_status_display_format html;}}

After restarting nginx, visit http://172.22.3.164:10011/stub_status

Install nginx-vts-exporter

Install nginx-vts-exporter on the nginx server

# cd / opt/# wget https://github.com/hnlq715/nginx-vts-exporter/releases/download/v0.10.3/nginx-vts-exporter-0.10.3.linux-amd64.tar.gz# tar-zxf nginx-vts-exporter-0.10.3.linux-amd64.tar.gz# cp nginx-vts-exporter-0.10.3.linux-amd64/nginx-vts-exporter / usr/local/bin

Create service

# # create service# vi / usr/lib/systemd/system/nginx-vts-exporter.service [Unit] Description=nginx-vts-exporterDocumentation= https://prometheus.io/After=network.target[Service]Type=simpleUser=rootExecStart=/usr/local/bin/nginx-vts-exporter\-nginx.scrape_timeout 10\-nginx.scrape_uri http://127.0.0.1:10011/nginx_status/format/jsonRestart=on-failure[Install]WantedBy=multi-user.target

Set up automatic start

# systemctl daemon-reload## setup self-boot # systemctl enable nginx-vts-exporterCreated symlink from / etc/systemd/system/multi-user.target.wants/nginx-vts-exporter.service to / usr/lib/systemd/system/nginx-vts-exporter.service. Configure nginx-vts-exporter Monitoring

Modify the prometheus configuration file prometheus.yml and add the following configuration under scrape_configs

-job_name: 'nginx-hosts' file_sd_configs:-files: [' / opt/prometheus/sd_config/nginx-hosts.yml'] refresh_interval: 5s

Add / opt/prometheus/sd_config/docker-hosts.yml file, which is as follows

Cat / opt/prometheus/sd_config/nginx-hosts.yml- targets:-172.22.3.164pur9913

Restart prometheus

# systemctl restart prometheus

Enter http://172.22.3.148:9090/targets in the browser address bar

You can see that targets has increased its monitoring of the service nginx-hosts

Configure the panel to display the monitoring content of the host nginx-hosts in grafana

Click the "+" button to pop up the import panel window

If you enter 2949 in the figure, click Load,grafana to import the panel numbered 2949 directly from the official website as follows

Select the data source Prometheus, continue with "Import", and display the nginx monitoring interface as follows
