# POST /2013-04-01/healthcheck

`POST /2013-04-01/healthcheck`

Creates a new health check.

For information about adding health checks to resource record sets, see [HealthCheckId](https://docs.aws.amazon.com/Route53/latest/APIReference/API_ResourceRecordSet.html#Route53-Type-ResourceRecordSet-HealthCheckId) in [ChangeResourceRecordSets](https://docs.aws.amazon.com/Route53/latest/APIReference/API_ChangeResourceRecordSets.html).

**ELB Load Balancers**

If you're registering EC2 instances with an Elastic Load Balancing (ELB) load balancer, do not create Amazon Route 53 health checks for the EC2 instances. When you register an EC2 instance with a load balancer, you configure settings for an ELB health check, which performs a similar function to a Route 53 health check.

**Private Hosted Zones**

You can associate health checks with failover resource record sets in a private hosted zone. Note the following:

*   Route 53 health checkers are outside the VPC. To check the health of an endpoint within a VPC by IP address, you must assign a public IP address to the instance in the VPC.
    
*   You can configure a health checker to check the health of an external resource that the instance relies on, such as a database server.
    
*   You can create a CloudWatch metric, associate an alarm with the metric, and then create a health check that is based on the state of the alarm. For example, you might create a CloudWatch metric that checks the status of the Amazon EC2 `StatusCheckFailed` metric, add an alarm to the metric, and then create a health check that is based on the state of the alarm. For information about creating CloudWatch metrics and alarms by using the CloudWatch console, see the [Amazon CloudWatch User Guide](https://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/WhatIsCloudWatch.html).
