Monitoring is crucial to measure the performance of applications running in a production environment. This Terraform / Helm project allows you to deploy a monitoring stack composed of two popular open-source tools: Prometheus and Grafana.
- Terraform init
- Terraform validate
- Terraform plan --out terraform.plan
- Terraform apply "terraform.plan"
- Terraform destroy
- Node exporter
Node exporter is responsible for fetching the statistics from various hardware and virtual resources in the format which Prometheus can understand and with the help of the prometheus server those statistics can be exposed on port 9100.
- Prometheus
Prometheus is an open-source tool for scrapping the performance metrics of any given hardware resource (CPU, VM, Cloud Virtual Machine, Router, etc.). The architecture is really scalable and 3rd party libraries makes it more powerful.
- Grafana
Grafana is an open-source analytics and visualization tool for viewing the metrics scraped by Prometheus from various resources. Grafana does not store any data, but instead, it relies on Prometheus to send the data so that dashboard can be prepared.
This guide will be a step-by-step tutorial. To follow along, be sure to have the following:
- Kubectl
- Helm
- Terraform
- CI/CD pipelines: For further agility and flexibility.
