# Monitoring module 
This module deploys the default cloudwatch metric monitoring

## Notes
Terraform lifecycle ignores tags to speed up terraform subsequent update. Cloudwatch alarm tags cannot be read on aws console anyway.

## Example
```terraform
module "ec2-instances" {
  source        = "../../modules/util/resource-list"
  resource-type = "ec2"
}

module "ec2-monitoring" {
  cw-alarm-prefix            = local.cw-alarm-prefix
  for_each                   = module.ec2-instances.result-set
  source                     = "../../modules/ManagementGovernance/Monitoring.EC2"
  default-tags               = local.default-tags
  ec2-instance-id            = each.value
  threshold-CPUUtilization   = 90
  threshold-mem_free         = 100000
  threshold-swap_free        = 100000
  threshold-disk_free        = 1 * 1000 * 1000 * 1000
  threshold-disk_inodes_free = 10000
  threshold-processes_total  = 500
  threshold-LogicalDiskFreePct = 10
  threshold-MemoryCommittedPct = 90
  actions-enabled            = var.actions-enabled
  sns-targets = var.sns-targets
}
