Logging

Overview

The logging variable controls where the Upwind components send their logs. By default, the module creates a CloudWatch log group and sends the logs of the sensor, scanner, and cluster manager to it.

Attribute	Type	Default	Description
cloudwatch_log_group.enabled	bool	true	Whether the module creates the log group.
cloudwatch_log_group.name	string	""	The log group name. When empty, it is /aws/ecs/upwind/<ecs_cluster_name>.
cloudwatch_log_group.retention_in_days	number	1	The log retention in days.
log_configuration	any	null	A custom ECS log configuration. When set, the module creates no log group.

CloudWatch log group

Change the name and retention of the log group:

module "upwind_ecs_runtime" {
  source = "https://get.upwind.io/terraform/modules/aws-ecs-runtime/aws-ecs-runtime-1.5.1.tar.gz"

  ecs_cluster_name = "my-ecs-cluster"
  vpc_id           = "vpc-0123456789abcdef0"
  subnets          = ["subnet-0123456789abcdef0", "subnet-0fedcba9876543210"]

  credentials = {
    client_id     = var.upwind_client_id
    client_secret = var.upwind_client_secret
  }

  logging = {
    cloudwatch_log_group = {
      name              = "/aws/ecs/upwind/my-ecs-cluster"
      retention_in_days = 14
    }
  }
}

Custom log configuration

To use another log driver, set log_configuration. The module passes it to the containers as their ECS logConfiguration, and creates no log group. Use logDriver and options as the keys.

logging = {
  log_configuration = {
    logDriver = "awslogs"
    options = {
      "awslogs-group"         = "/my/existing/log-group"
      "awslogs-region"        = "us-east-1"
      "awslogs-stream-prefix" = "upwind"
    }
  }
}

If you set cloudwatch_log_group.enabled = false and no log_configuration, the components have no log configuration.
