NGINX Metrics

deb (Debian/Ubuntu/Mint)

curl -L -O https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-oss-7.8.1-amd64.deb
sudo dpkg -i metricbeat-oss-7.8.1-amd64.deb

rpm (CentOS/RHEL/Fedora)

curl -L -O https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-oss-7.8.1-x86_64.rpm
sudo rpm -vi metricbeat-oss-7.8.1-x86_64.rpm

macOS

curl -L -O https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-oss-7.8.1-darwin-x86_64.tar.gz
tar xzvf metricbeat-oss-7.8.1-darwin-x86_64.tar.gz

Windows

• Download the metricbeat Windows zip file from the official downloads page.
• Extract the contents of the zip file into C:\Program Files.
• Rename the metricbeat-<version>-windows directory to metricbeat.
• Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator). If you are running Windows XP, you may need to download and install PowerShell.
• Run the following commands to install metricbeat as a Windows service:

cd 'C:\Program Files\metricbeat'
.\install-service-metricbeat.ps1

deb/rpm /etc/metricbeat/metricbeat.yml
mac/win <EXTRACTED_ARCHIVE>/metricbeat.yml

We'll be shipping to Logstash so that we have the option to run filters before the data is indexed.
Comment out the elasticsearch output block.

## Comment out elasticsearch output
#output.elasticsearch:
#  hosts: ["localhost:9200"]

Uncomment and change the logstash output to match below.

output.logstash:
    hosts: ["your-logstash-host:your-ssl-port"]
    loadbalance: true
    ssl.enabled: true

Let's check the configuration file is syntactically correct by running metricbeat directly inside the terminal. If the file is invalid, metricbeat will print an error loading config file error message with details on how to correct the problem.

deb/rpm

sudo metricbeat -e -c /etc/metricbeat/metricbeat.yml

macOS

cd <EXTRACTED_ARCHIVE>
./metricbeat -e -c metricbeat.yml

Windows

cd <EXTRACTED_ARCHIVE>
.\metricbeat.exe -e -c metricbeat.yml

There are several built in metricbeat modules you can use. To enable the NGINX module, run the following:

deb/rpm

metricbeat modules list
metricbeat modules enable nginx

macOS

./metricbeat modules list
./metricbeat modules enable nginx

Windows

PS > .\metricbeat.exe modules enable nginx

Each module has its own configuration file where different metricsets can be enabled / disabled. Locate the configuration file for the NGINX module.

deb/rpm /etc/metricbeat/modules.d/nginx.yml

mac/win ~/<EXTRACTED_ARCHIVE>/modules.d/nginx.yml

By default the stubstatus metricset is disabled. To enable or disable a metric simply comment or uncomment the line out.

- module: nginx
  metricsets:
    - stubstatus
  period: 10s

  # NGINX hosts
  hosts: ["http://127.0.0.1"]

  # Path to server status. Default server-status
  server_status_path: "nginx_status"

  #username: "user"
  #password: "secret"

In order for the status metricset to work and correctly display the dashboard on Kibana, you will need to enable ngx_http_stub_status on your NGINX web server.

Ok, time to start gathering metrics!

deb/rpm

sudo systemctl enable metricbeat
sudo systemctl start metricbeat

macOS

./metricbeat

Windows

PS C:\Program Files\Metricbeat> Start-Service metricbeat

The NGINX metricsets were tested with NGINX 1.9 and are expected to work with all versions >= 1.9.

The NGINX module comes with a predefined Kibana dashboard. To view your dashboards for any of your Logit stacks, launch Kibana and choose Dashboards.
