fleet/terraform/addons/monitoring

Monitoring addon

This addon enables Cloudwatch monitoring for Fleet.

This includes:

• 5XX Errors on ALB
• ECS Service Monitoring
• RDS Monitoring
• Redis Monitoring
• ACM Certificate Monitoring

Preparation

Some of the for_each and counts in this module cannot pre-determine the numbers until the main fleet module is applied.

You will need to terraform apply -target module.main prior applying monitoring assuming the use of a configuration matching the example at https://github.com/fleetdm/fleet/blob/main/terraform/example/main.tf.

Example Configuration

This assumes your fleet module is main and is configured with it's default documentation.

See https://github.com/fleetdm/fleet/blob/main/terraform/example/main.tf for details.

module "monitoring" {
  source                      = "github.com/fleetdm/fleet//terraform/addons/monitoring?ref=main"
  fleet_ecs_service_name      = module.main.byo-vpc.byo-db.byo-ecs.service.name
  fleet_min_containers        = module.main.byo-vpc.byo-db.byo-ecs.service.desired_count
  alb_name                    = module.main.byo-vpc.byo-db.alb.lb_dns_name
  alb_target_group_name       = module.main.byo-vpc.byo-db.alb.target_group_names[0]
  alb_target_group_arn_suffix = module.main.byo-vpc.byo-db.alb.target_group_arn_suffixes[0]
  alb_arn_suffix              = module.main.byo-vpc.byo-db.alb.lb_arn_suffix
  default_sns_topic_arns      = [var.sns_topic_arn]
  mysql_cluster_members       = module.main.byo-vpc.rds.cluster_members
  redis_cluster_members       = module.main.byo-vpc.redis.member_clusters[0]
  acm_certificate_arn         = module.acm.acm_certificate_arn
