Google Kubernetes Engine Metrics via Telegraf

Ship your Google Kubernetes Engine Metrics via Telegraf to your Logit.io Stack

Configure Telegraf to ship Google Kubernetes Engine metrics to your Logit.io stacks via Logstash.

Install Integration

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

Set Credentials in GCP

@intro

Begin by heading over to the 'Project Selector' (opens in a new tab) and select the specific project from which you wish to send metrics.
- Progress to the 'Service Account Details' screen. Here, assign a distinct name to your service account and opt for 'Create and Continue'.
- In the 'Grant This Service Account Access to Project' screen, ensure the following roles: 'Compute Viewer', 'Monitoring Viewer', and 'Cloud Asset Viewer'.
- Upon completion of the above, click 'Done'.
- Now find and select your project in the 'Service Accounts for Project' list.
- Move to the 'KEYS' section.
- Navigate through Keys > Add Key > Create New Key, and specify 'JSON' as the key type.
- Lastly, click on 'Create', and make sure to save your new key.
Now add the environment variable for the key

On the machine run:
```
export GOOGLE_APPLICATION_CREDENTIALS=<your-gcp-key>
```

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

First you need to set up the input plug-in to enable Telegraf to scrape the GCP data from your hosts. This can be accomplished by incorporating the following code into your configuration file:

# Gather timeseries from Google Cloud Platform v3 monitoring API
[[inputs.stackdriver]]
  ## GCP Project
  project = "<your-project-name>"
 
  ## Include timeseries that start with the given metric type.
  metric_type_prefix_include = [
	"@metric_type",
  ]
 
  ## Most metrics are updated no more than once per minute; it is recommended
  ## to override the agent level interval with a value of 1m or greater.
  interval = "1m"

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 Google Kubernetes Engine Platform metrics Overview

To ensure effective monitoring and analysis of Google Kubernetes Engine clusters, it is important to implement a robust metrics management solution. Telegraf, an open-source server agent, is widely recognized for its ability to collect and report metrics from various sources, including cluster resource utilization, node health, and container performance.

Telegraf offers a wide range of input plugins that enable users to collect diverse metrics related to Kubernetes cluster performance, such as CPU and memory usage, network traffic, and pod status. These metrics provide valuable insights into the efficiency and health of Kubernetes deployments.

For storing and analyzing these metrics, organizations can leverage Prometheus, an open-source monitoring and alerting toolkit known for its flexible query language and powerful data visualization capabilities. The process of transmitting Google Kubernetes Engine metrics from Telegraf to Prometheus involves configuring Telegraf to present metrics in Prometheus's format and instructing Prometheus to scrape these metrics from the Telegraf server.

Once the metrics are successfully integrated into Prometheus, organizations can perform comprehensive analysis and visualization using Grafana. Grafana, a leading open-source platform for monitoring and observability, seamlessly integrates with Prometheus, allowing users to create dynamic and interactive dashboards to monitor Kubernetes cluster performance, troubleshoot issues, and optimize resource utilization.
