getInstancesHealthStatus method
Gets the current health status (Healthy
,
Unhealthy
, or Unknown
) of one or more instances
that are associated with a specified service.
May throw InstanceNotFound. May throw InvalidInput. May throw ServiceNotFound.
Parameter serviceId
:
The ID of the service that the instance is associated with.
Parameter instances
:
An array that contains the IDs of all the instances that you want to get
the health status for.
If you omit Instances
, AWS Cloud Map returns the health
status for all the instances that are associated with the specified
service.
Parameter maxResults
:
The maximum number of instances that you want AWS Cloud Map to return in
the response to a GetInstancesHealthStatus
request. If you
don't specify a value for MaxResults
, AWS Cloud Map returns
up to 100 instances.
Parameter nextToken
:
For the first GetInstancesHealthStatus
request, omit this
value.
If more than MaxResults
instances match the specified
criteria, you can submit another GetInstancesHealthStatus
request to get the next group of results. Specify the value of
NextToken
from the previous response in the next request.
