Account-Scoped Filtering: Filters metrics by team and environment
CPU & Memory Tracking: Timeseries visualization for top containers
Read-Only Dashboard: Prevents accidental modifications
EU Datadog Instance: Configured for European GDPR compliance

Resources Created

datadog_dashboard: Application monitoring dashboard with account-scoped widgets

Dashboard Widgets

Kubernetes Pods Hostmap: CPU utilization by Docker image (account-scoped)
CPU Utilization Timeseries: Container CPU usage
Kubernetes Nodes Hostmap: CPU utilization by host
Memory Utilization Timeseries: Container memory usage

Requirements

Name	Version
terraform	>= 0.12
datadog	>= 3.5.0

Usage

module "slack_dashboard" {
  source = "./terraform-datadog-slack"

  opco_name  = "sanoma"

  team_name  = "platform-team"
  image_name = "slack-app"
  aws_region = "eu-west-1"
  env        = "prd"
  api_key    = var.datadog_api_key
  app_key    = var.datadog_app_key
  url        = "https://slack.example.com/health"
}

Outputs

Currently, this module does not export any outputs.

Account Scoping

The dashboard filters metrics using account-based scoping:

Scope: account:{team_name}_{env}
This ensures each team only sees their environment's metrics

Differences from terraform-datadog-app-dashboard

While similar to the app-dashboard module, this version:

Uses account-scoped filtering instead of namespace
Configured specifically for EU Datadog API
Simplified widget set (no alert graph)
Synthetics integration is commented out
Uses OPCO name instead of CFA name

Provider Configuration

API URL: https://api.datadoghq.eu (EU instance)
Datadog Provider: Version 3.5.0 or higher

Notes

Dashboard is read-only to prevent accidental modifications
All widgets filter by account scope {team_name}_{env}
Designed for multi-tenant Kubernetes environments
Uses EU Datadog API endpoint for GDPR compliance
