Apache HTTP Server

Ship your Apache HTTP Server Metrics via Telegraf to your Logit.io Stack

Follow the steps below to send your observability data to Logit.io

Metrics

Configure Telegraf to ship Apache HTTP Server metrics to your Logit.io stacks via Logstash.

Install Integration

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

Install Telegraf

This integration allows you to configure a Telegraf agent to send your metrics 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-1.34.1.

wget https://dl.influxdata.com/telegraf/releases/telegraf-1.34.1_windows_amd64.zip -UseBasicParsing -OutFile telegraf-1.34.1_windows_amd64.zip 
Expand-Archive .\telegraf-1.34.1_windows_amd64.zip -DestinationPath 'C:\Program Files\InfluxData\telegraf'

or in Powershell 7 use:

# Download the Telegraf ZIP file
Invoke-WebRequest -Uri "https://dl.influxdata.com/telegraf/releases/telegraf-1.34.1_windows_amd64.zip" `
                -OutFile "telegraf-1.34.1_windows_amd64.zip" `
                -UseBasicParsing
 
# Extract the contents of the ZIP file
Expand-Archive -Path ".\telegraf-1.34.1_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 Apache status information (mod_status)
[[inputs.apache]]
  ## An array of URLs to gather from, must be directed at the machine
  ## readable version of the mod_status page including the auto query string.
  ## Default is "http://localhost/server-status?auto".
  urls = ["http://localhost/server-status?auto"]
 
  ## Credentials for basic HTTP authentication.
  # username = "myuser"
  # password = "mypassword"
 
  ## Maximum time to receive response.
  # response_timeout = "5s"
 
  ## 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

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:

[[inputs.tail]]
  name_override = "nginxlog"
  files = ["<Nginx installation directory>/logs/access.log"]
  from_beginning = true
  pipe = false
  data_format = "grok"
  grok_patterns = ["%{COMBINED_LOG_FORMAT}"]
 
[[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"

Remember to replace <Nginx installation directory> with the directory where your Nginx is located.

Start Telegraf

From the location where Telegraf was installed (C:\Program Files\InfluxData\telegraf\telegraf-1.34.1) run the program providing the chosen configuration file as a parameter:

.\telegraf.exe --config telegraf.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:

Telegraf Apache HTTP Server Overview

For effective monitoring and analyzing Apache HTTP metrics in a distributed environment, it's crucial to have a dependable and capable metrics management solution. Telegraf, an open-source agent for collecting and transmitting metrics, is an ideal choice for gathering Apache HTTP metrics from numerous sources, such as live Apache servers, databases, and other applications.

Telegraf provides a broad spectrum of input plugins, allowing the collection of metrics from diverse sources including CPU usage, memory consumption, network activity, and more. To store and query these accumulated metrics, organizations can leverage Prometheus, an open-source monitoring and alerting system that supports a flexible querying language and graphic data visualization.

To ship Apache metrics from Telegraf to Prometheus, organizations need to configure Telegraf to output metrics in the Prometheus format, then utilize Prometheus to scrape these metrics from the Telegraf server. This procedure involves setting up Telegraf to gather Apache metrics and output them in the Prometheus format, configuring Prometheus to extract these metrics from the Telegraf server, and then analyzing and visualizing the data using Prometheus's flexible querying capabilities.

Once the metrics are in Prometheus, they can be further analyzed and visualized using Grafana. Grafana is an open-source platform for monitoring and observability, and it's perfectly compatible with Prometheus. It provides users with the ability to create dynamic and interactive dashboards to drill down into the metrics data. This integration provides organizations with a powerful toolset to gain valuable insights into Apache performance, enabling them to optimize and troubleshoot their distributed Apache systems effectively.

Using Telegraf to ship Apache metrics to Prometheus, followed by analysis and visualization with Grafana, is a reliable and efficient method for managing metrics in distributed environments. This strategy equips organizations with the ability to optimize their distributed systems and promptly address any arising issues.
