Account - List Pool Node Counts

Service:

Batch Service

API Version:

2023-11-01.18.0

Gets the number of Compute Nodes in each state, grouped by Pool. Note that the numbers returned may not always be up to date. If you need exact node counts, use a list query.

GET {batchUrl}/nodecounts?api-version=2023-11-01.18.0

With optional parameters:

GET {batchUrl}/nodecounts?$filter={$filter}&maxresults={maxresults}&timeout={timeout}&api-version=2023-11-01.18.0

URI Parameters

Name	In	Required	Type	Description
batchUrl	path	True	string	The base URL for all Azure Batch service requests.
api-version	query	True	string	Client API Version.
$filter	query		string	An OData $filter clause. For more information on constructing this filter, see https://docs.microsoft.com/en-us/rest/api/batchservice/odata-filters-in-batch.
maxresults	query		integer int32	The maximum number of items to return in the response.
timeout	query		integer int32	The maximum time that the server can spend processing the request, in seconds. The default is 30 seconds.

Request Header

Media Types: "application/json; odata=minimalmetadata"

Name	Required	Type	Description
client-request-id		string uuid	The caller-generated request identity, in the form of a GUID with no decoration such as curly braces, e.g. 9C4D50EE-2D56-4CD3-8152-34347DC9F2B0.
return-client-request-id		boolean	Whether the server should return the client-request-id in the response.
