Nginx Metrics

Ship your Nginx Metrics via Telegraf to your Logit.io Stack

Configure Telegraf to ship Nginx metrics to your Logit.io stacks via Logstash.

Install Integration

Please click on the Install Integration button to configure your stack for this source.

Configure Nginx

Update the NGINX configuration file (nginx.conf) to enable the stub_status module:

server {
  listen 127.0.0.1:80;
  server_name 127.0.0.1;
  location /nginx_status {
    stub_status on;
    allow <Your localhost address>;
    deny all;
  }
}

Replace <Your localhost address> with your localhost address and restart Nginx.

Install Telegraf

This integration allows you to configure a Telegraf agent to send your metrics, in multiple formats, to Logit.io.

Choose the installation method for your operating system:

When you paste the command below into Powershell it will download the Telegraf zip file. Once that is complete, press Enter again and the zip file will be extracted into C:\Program Files\InfluxData\telegraf\telegraf-1.31.2.

wget https://dl.influxdata.com/telegraf/releases/telegraf-1.31.2_windows_amd64.zip -UseBasicParsing -OutFile telegraf-1.31.2_windows_amd64.zip 
Expand-Archive .\telegraf-1.31.2_windows_amd64.zip -DestinationPath 'C:\Program Files\InfluxData\telegraf'

Configure the Telegraf input plugin

The configuration file below is pre-configured to scrape the system metrics from your hosts, add the following code to the configuration file /etc/telegraf/telegraf.conf from the previous step.

# Read Nginx's basic status information (ngx_http_stub_status_module)
[[inputs.nginx]]
## An array of Nginx stub_status URI to gather stats.
urls = ["http://localhost/server_status"]
 
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
 
## HTTP response timeout (default: 5s)
response_timeout = "5s"
 
[[inputs.disk]]
[[inputs.net]]
[[inputs.mem]]
[[inputs.system]]
[[inputs.cpu]]
 
percpu = false
totalcpu = true
collect_cpu_time = true
report_active = true

Configure the output plugin

Once you have generated the configuration file, you need to set up the output plug-in to allow Telegraf to transmit your data to Logit.io in Prometheus format. This can be accomplished by incorporating the following code into your configuration file:

[[outputs.http]]
  url = "https://@metricsUsername:@metricsPassword@@metrics_id-vm.logit.io:@vmAgentPort/api/v1/write"
  data_format = "prometheusremotewrite"
 
  [outputs.http.headers]
    Content-Type = "application/x-protobuf"
    Content-Encoding = "snappy"

Start Telegraf

From the location where Telegraf was installed (C:\Program Files\InfluxData\telegraf\telegraf-1.31.2) run the program providing the chosen configuration file as a parameter:

.\telegraf.exe --config telegraf-demo.conf

Once Telegraf is running you should see output similar to the following, which confirms the inputs, output and basic configuration the application has been started with: Powershell Telegraf information

Telegraf Nginx metrics Overview

To effectively monitor and analyze Nginx metrics in a distributed environment, organizations need a reliable and efficient metrics management solution. Telegraf is an open-source metrics collection agent that can gather Nginx metrics from various sources, including operating Nginx, databases, and other applications.

With a wide range of input plugins, Telegraf allows users to collect metrics from different sources, such as CPU usage, memory usage, network activity, and more. To store and query the collected metrics, organizations can use Prometheus, an open-source monitoring and alerting tool that supports a flexible querying language and graphical visualization of data.

By configuring Telegraf to output metrics in the Prometheus format and using Prometheus to scrape the metrics from the Telegraf server, organizations can ship Nginx metrics from Telegraf to Prometheus. This process involves setting up Telegraf to collect Nginx metrics, outputting them in the Prometheus format, configuring Prometheus to scrape the metrics from the Telegraf server, and visualizing the data using Prometheus' flexible querying and graphical visualization capabilities.

Using Telegraf to ship Nginx metrics to Prometheus is a reliable and efficient metrics management solution for distributed environments. It allows organizations to gain insights into Nginx performance, optimize their distributed Nginx, and troubleshoot any issues that arise.
