isInstanceAlive method
Check alive status This endpoint returns a 200 status code when the HTTP server is up running. This status does currently not include checks whether the database connection is working. If the service supports TLS Edge Termination, this endpoint does not require the `X-Forwarded-Proto` header to be set. Be aware that if you are running multiple nodes of this service, the health status will never refer to the cluster state, only to a single instance.
Parameters:
cancelToken
- ACancelToken
that can be used to cancel the operationheaders
- Can be used to add additional headers to the requestextras
- Can be used to add flags to the requestvalidateStatus
- AValidateStatus
callback that can be used to determine request success based on the HTTP status of the responseonSendProgress
- AProgressCallback
that can be used to get the send progressonReceiveProgress
- AProgressCallback
that can be used to get the receive progress
Returns a Future containing a Response
with a HealthStatus as data
Throws DioError
if API call or serialization fails
