  stage                   = "prod"
  alb_name                = "cp-prod-app-alb"

Inputs

Name Description Type Default Required
alarm_actions A list of ARNs (i.e. SNS Topic ARN) to execute when this alarm transitions into an ALARM state from any other state. If set, this list takes precedence over notify_arns. list <list> no
alb_arn_suffix The ARN suffix of ALB. string - yes
alb_name The name of ALB to monitor. string - yes
attributes List of attributes to add to label. list <list> no
delimiter The delimiter to be used in labels. string - no
enabled Whether to create all resources. string true no
evaluation_periods Number of periods to evaluate for the alarm. string 1 no
httpcode_alarm_description The string to format and use as the httpcode alarm description. string HTTPCode %v count for %v over %v last %d minute(s) over %v period(s) no
insufficient_data_actions A list of ARNs (i.e. SNS Topic ARN) to execute when this alarm transitions into an INSUFFICIENT_DATA state from any other state. If set, this list takes precedence over notify_arns. list <list> no
name Name (unique identifier for app or service) string - yes
namespace Namespace (e.g. cp or cloudposse) string - yes
notify_arns A list of ARNs (i.e. SNS Topic ARN) to execute when this alarm transitions into ANY state from any other state. May be overridden by the value of a more specific {alarm,ok,insufficient_data}_actions variable. list <list> no
ok_actions A list of ARNs (i.e. SNS Topic ARN) to execute when this alarm transitions into an OK state from any other state. If set, this list takes precedence over notify_arns. list <list> no
period Duration in seconds to evaluate for the alarm. string 300 no
stage Stage (e.g. prod, dev, staging) string - yes
tags Map of key-value pairs to use for tags. map <map> no
target_3xx_count_threshold The maximum count of 3XX requests over a period. A negative value will disable the alert. string 25 no
target_4xx_count_threshold The maximum count of 4XX requests over a period. A negative value will disable the alert. string 25 no
target_5xx_count_threshold The maximum count of 5XX requests over a period. A negative value will disable the alert. string 25 no
elb_5xx_count_threshold The maximum count of ELB 5XX requests over a period. A negative value will disable the alert. string 25 no
target_group_arn_suffix The ARN suffix of ALB Target Group. string - yes
