Datadog

What Is Datadog

Datadog is an observability service for cloud-scale applications, providing monitoring of servers, databases, tools, and services, through a SaaS-based data analytics platform. It provides cloud-scale monitoring and security for metrics, traces and logs in one unified platform.

DataDog Agent Installation

There are 3 ways in offical docs for installing the Datadog Agent on Kubernetes, but here I tried another way with Terraform Helm Provider.

Prerequisites

• Kubernetes 1.22
• Terraform 1.2.9
• Terraform Helm Provider 2.6.0

My example setup DD agent and test in GCP. Similar way if you use AWS/Azure.

1. Get Datadog API and application keys first.
2. Upload keys to GCP Secret Manager
3. Execution

cd datadog_agent_install

terraform init
terraform plan 
terraform apply

Monitoring as Code

MaC examples as below:

• Availability level
  • availability_gke_demo_pods_monitor
  • availability_gke_deploy_replicas_monitor
  • availability_process_down_monitor
  • availability_synthetics_api_test
  • availability_synthetics_ssl_test
  • availability_vm_instance_monitor
• Infrastructure level
  • infra_cpu_high_load_monitor
  • infra_disk_low_space_monitor
• System level
  • system_log_monitor
  • system_process_high_cpu_monitor
• Dashboard
  • datadog_dashboard_example
