Redfish Metrics via Telegraf
Ship your Redfish Metrics via Telegraf to your Logit.io Stack
Configure Telegraf to ship Redfish metrics to your Logit.io stacks via Logstash.
Follow this step by step guide to get 'logs' from your system to Logit.io:
Step 1 - Install Telegraf
This integration allows you to configure a Telegraf agent to send your metrics, in multiple formats, to Logit.io.
Telegraf is a flexible server agent equipped with plug-in support, useful for sending metrics and events from data sources like web servers, APIs, application logs, and cloud services.
To ship your metrics to Logit.io, we will integrate the relevant input and outputs.http plug-in into your Telegraf configuration file.
Choose the install for your operating system below to get started:
Windows
wget https://dl.influxdata.com/telegraf/releases/telegraf-1.19.2_windows_amd64.zip
Download and extract to: C:\Program Files\Logitio\telegraf\
Configuration file: C:\Program Files\Logitio\telegraf\
MacOS
brew install telegraf
Configuration file x86_64 Intel: /usr/local/etc/telegraf.conf
Configuration file ARM (Apple Silicon): /opt/homebrew/etc/telegraf.conf
Ubuntu/Debian
wget -q https://repos.influxdata.com/influxdata-archive_compat.key
echo '393e8779c89ac8d958f81f942f9ad7fb82a25e133faddaf92e15b16e6ac9ce4c influxdata-archive_compat.key' | sha256sum -c && cat influxdata-archive_compat.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.list
sudo apt-get update
sudo apt-get install telegraf
Configuration file: /etc/telegraf/telegraf.conf
RedHat and CentOS
cat <<EOF | sudo tee /etc/yum.repos.d/influxdata.repo
[influxdata]
name = InfluxData Repository - Stable
baseurl = https://repos.influxdata.com/stable/\$basearch/main
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdata-archive_compat.key
EOF
sudo yum install telegraf
Configuration file: /etc/telegraf/telegraf.conf
SLES & openSUSE
zypper ar -f obs://devel:languages:go/ go
zypper in telegraf
Configuration file: /etc/telegraf/telegraf.conf
FreeBSD/PC-BSD
sudo pkg install telegraf
Configuration file: /etc/telegraf/telegraf.conf
Step 2 - 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
Step 3 - 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://<your-metrics-username>:<your-metrics-password>@<your-metrics-stack-id>-vm.logit.io:0/api/v1/write"
data_format = "prometheusremotewrite"
[outputs.http.headers]
Content-Type = "application/x-protobuf"
Content-Encoding = "snappy"
Step 4 - Start Telegraf
Windows
telegraf.exe --service start
MacOS
telegraf --config telegraf.conf
Linux
sudo service telegraf start
for systemd installations
systemctl start telegraf
Step 5 - View your metrics
Data should now have been sent to your Stack.
If you don't see metrics take a look at How to diagnose no data in Stack below for how to diagnose common issues.

Step 7 - 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.
