Infrastructure Monitoring¶

Overview¶

This directory contains the monitoring configuration for the infrastructure. The monitoring system tracks the health and performance of the infrastructure components, including AWS resources, Kubernetes clusters, and networking.

Components¶

Prometheus: Collects and stores metrics
Grafana: Visualizes metrics and provides dashboards
Alertmanager: Manages alerts and notifications
CloudWatch Exporter: Provides AWS-specific metrics
Node Exporter: Provides host-level metrics
Blackbox Exporter: Provides network probing metrics

Metrics¶

The following metrics are collected:

AWS resource usage
Kubernetes cluster health
Node resource usage
Network connectivity
Service availability
Cost metrics
Security metrics

Dashboards¶

The following dashboards are available:

Infrastructure Overview: General infrastructure metrics
AWS Resources: Detailed AWS resource metrics
Kubernetes: Kubernetes cluster metrics
Network: Network connectivity metrics
Cost: Cost analysis metrics
Security: Security posture metrics

Setup¶

The monitoring system is automatically set up during the infrastructure provisioning. You can also set it up manually:

terraform apply -target=module.monitoring

Accessing Dashboards¶

Once the monitoring system is running, you can access the dashboards at:

Grafana: https://grafana.<your-domain>
Prometheus: https://prometheus.<your-domain>

Configuration¶

The monitoring configuration can be customized by editing the following files:

terraform/modules/monitoring/*.tf: Terraform configuration
terraform/modules/monitoring/templates/*.yaml: Kubernetes resources
terraform/modules/monitoring/dashboards/*.json: Grafana dashboards

Integration with Logging¶

The monitoring system is integrated with the logging system. Metrics about log volume and errors are available in the monitoring dashboards.
