This Terraform module, basic-monitoring, is designed to set up AWS monitoring for specified endpoints. It includes functionality for Route 53 health checks, SNS alerts, and CloudWatch alarms. This module supports both HTTPS
and HTTPS_STR_MATCH
checks, allowing configuration of various endpoints with customizable settings.
- Route 53 Health Checks: Configurable health checks for multiple endpoints, supporting both HTTPS-only and HTTPS with string matching.
- SNS Alerts: A single SNS topic that sends notifications to a specified email when health checks fail.
- CloudWatch Alarms: Monitors health check statuses and triggers alerts via SNS.

fqdn
(string): The fully qualified domain name (FQDN) for the health checks.port
(number): The port number for health checks (e.g., 443 for HTTPS).health_check_regions
(list(string)): List of AWS regions where health checks should be monitored. Default regions are["us-west-1", "us-west-2", "eu-west-1"]
.email
(string): The email address to send SNS alerts.endpoints
(list(object)):resource_path
(string): The path on the FQDN to be checked.search_string
(string): The expected response string (only required forHTTPS_STR_MATCH
checks; leave blank forHTTPS
checks).request_interval
(number): The interval in seconds between health check requests.failure_threshold
(number): The number of consecutive health check failures required to trigger an alert.type
(string): Specifies the type of health check. Use"HTTPS"
for HTTPS checks and"HTTPS_STR_MATCH"
for HTTPS checks with a required string match.
health_check_ids
(map): A map of health check IDs for each configured endpoint.sns_topic_arn
(string): ARN of the SNS topic used for health check alerts.
This Terraform module, lambda-monitoring, is designed to set up AWS monitoring and reporting for a lambda mfunction. It includes functionality for lambda and CloudWatch alarms.
- SNS Alerts: A single SNS topic that sends notifications to a specified email when health checks fail.
- CloudWatch Alarms: Monitors health check statuses and triggers alerts via SNS.
