ELB Status Plugin

Identifying unhealthy instances for a given load balancer can be a challenge because there can be multiple target-groups associated with a given load balancer, and multiple instances associated within a Target Group. This plugin checks all instances for all Target Groups "within" a given ELB and returns any that are "unhealthy."

  • Target Load Balancer: The name of the Elastic Load Balancer (ELB) that routes traffic to the Target Group instances.
  • Target Load Balancer Region: The AWS region where the ELB resides.
