Fail2ban Metrics

Ship your Fail2ban Metrics via Telegraf to your Logit.io Stack

Configure Telegraf to ship Fail2ban 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, 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 metrics from fail2ban.
[[inputs.fail2ban]]
  ## Use sudo to run fail2ban-client
  use_sudo = 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:

[[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 Fail2ban metrics Overview

In order to effectively monitor and analyze Fail2ban metrics in a distributed environment, it's essential to employ a trustworthy and efficient metrics management solution. Telegraf, an open-source metrics collection agent, is ideally suited for this task, capable of gathering Fail2ban metrics from a host of sources, including operational Fail2ban instances, databases, and other related applications.

Telegraf provides a broad assortment of input plugins, empowering users to collect metrics from diverse sources such as CPU usage, memory consumption, network activity, and more. To store and examine these collected metrics, organizations can make use of Prometheus, an open-source monitoring and alerting system renowned for its flexible querying language and robust graphical data visualization capabilities.

To ship Fail2ban metrics from Telegraf to Prometheus, organizations need to configure Telegraf to output metrics in the Prometheus format, and then arrange for Prometheus to scrape these metrics from the Telegraf server. This process involves configuring Telegraf to collect Fail2ban metrics, rendering them in the Prometheus format, setting up Prometheus to retrieve these metrics from the Telegraf server, and then visually interpreting the data using Prometheus's dynamic querying and graphical visualization tools.

Once the metrics are successfully transferred into Prometheus, further analysis and visualization can be conducted using Grafana. Grafana is an open-source platform recognized for its monitoring and observability capabilities, and is fully compatible with Prometheus. It allows users to construct dynamic, interactive dashboards, providing a deeper understanding of the metrics data and a more complete view of performance trends and potential issues.
