Redfish

Ship your Redfish 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 Redfish 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 CPU, Fans, Powersupply and Voltage metrics of hardware server through redfish APIs
[[inputs.redfish]]
  ## Redfish API Base URL.
  address = "https://127.0.0.1:5000"
 
  ## Credentials for the Redfish API.
  username = "root"
  password = "password123456"
 
  ## System Id to collect data for in Redfish APIs.
  computer_system_id="System.Embedded.1"
 
  ## Amount of time allowed to complete the HTTP request
  # 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:

[[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 Redfish Overview

For the effective monitoring and analysis of Redfish metrics in a distributed environment, a solid metrics management solution is key. Telegraf, an open-source server agent for collecting and reporting metrics, is ideally suited for this role. It can gather Redfish metrics from various sources, including operational Redfish instances, databases, and other relevant applications.

Telegraf offers a comprehensive set of input plugins that enable users to collect diverse metrics, such as CPU usage, memory utilization, network traffic, and more, vital for understanding Redfish performance. To store and examine these harvested metrics, organizations can use Prometheus, an open-source monitoring and alerting toolkit recognized for its flexible querying language and potent data visualization capabilities.

The transmission of Redfish metrics from Telegraf to Prometheus requires configuring Telegraf to output metrics in the Prometheus format, and then setting up Prometheus to scrape these metrics from the Telegraf server. This process involves setting up Telegraf to collect Redfish metrics, outputting them in the Prometheus format, configuring 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 integrated into Prometheus, further analysis and visualization can be carried out using Grafana. Grafana is a leading open-source platform known for its monitoring and observability features, and is fully compatible with Prometheus. It allows users to create dynamic, interactive dashboards for a deeper dive into the metrics data, offering a comprehensive understanding of performance trends and potential issues within the Redfish system.
