Unzip nginx-module-vts-master.zip

Note here that the nginx version is required or an error will be reported. The following is the corresponding version of nginx.

two。 Extract the nginx.

Tar-zxvf nginx-1.14.2.tar.gz

3. Installation

Cd usr/local/nginx-1.14.2./configure-- prefix=/usr/local/nginx-- add-module=usr/local/nginx-module-vts-master/ Note: note that prefix=/usr/local/nginx means the installation location is / usr/local/nginx folder make install

4. Modify the conf file

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;}}

5. Start

Cd / usr/local/nginx/sbin./nginx

When accessing http://ip/status, the following display indicates that nginx and nginx-vts-exporter are installed successfully.

3. Install nginx-vts-exporter-0.9.1.linux-amd64.tar

Here the installation package is placed under usr/local and decompressed.

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

Activate.

Cd / usr/local/nginx-vts-exporter-0.9.1.linux-amd64nohup. / nginx-vts-exporter- nginx.scrape_uri http://ip/status/format/json &

Enter http://ip:9913/metrics, and if the following proof appears, complete.

4. Configure Prometheus

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

# my global configglobal: 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 configurationalerting: 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= `to any timeseries scraped from this config. -job_name: 'prometheus' static_configs:-targets: [' localhost:9090']-job_name: 'nginx' static_configs:-targets: [' ip:9913']

The following configuration is successful.

5. Configure Grafana

Enter the grafana visualization page address: ip:3000.
