-- | This action creates a new health check.
--
-- To create a new health check, send a 'POST' request to the '2013-04-01/healthcheck' resource. The request body must include an XML document with a 'CreateHealthCheckRequest' element. The response returns the 'CreateHealthCheckResponse' element that
-- contains metadata about the health check.
