Account - List Pool Node Counts

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=2024-07-01.20.0
GET {batchUrl}/nodecounts?$filter={$filter}&maxresults={maxresults}&timeout={timeout}&api-version=2024-07-01.20.0

api-version
query True

string

Client API Version.

$filter
query

string

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. If the value is larger than 30, the default will be used instead.
