# Gets load information about a Service Fabric application.

`GET /Applications/{applicationId}/$/GetLoadInformation`

Returns the load information about the application that was created or in the process of being created in the Service Fabric cluster and whose name matches the one specified as the parameter. The response includes the name, minimum nodes, maximum nodes, the number of nodes the application is occupying currently, and application load metric information about the application.

## Path parameters

- `applicationId` string, required

## Query parameters

- `api-version` '6.0', required
- `timeout` integer

## Response `200`

Information about the application load.

- ApplicationLoadInfo — Load Information about a Service Fabric application.
  - `Id` string — The identity of the application. This is an encoded representation of the application name. This is used in the REST APIs to identify the application resource. Starting in version 6.0, hierarchical names are delimited with the "\~" character. For example, if the application name is "fabric:/myapp/app1", the application identity would be "myapp\~app1" in 6.0+ and "myapp/app1" in previous versions.
  - `MinimumNodes` integer — The minimum number of nodes for this application. It is the number of nodes where Service Fabric will reserve Capacity in the cluster which equals to ReservedLoad * MinimumNodes for this Application instance. For applications that do not have application capacity defined this value will be zero.
  - `MaximumNodes` integer — The maximum number of nodes where this application can be instantiated. It is the number of nodes this application is allowed to span. For applications that do not have application capacity defined this value will be zero.
  - `NodeCount` integer — The number of nodes on which this application is instantiated. For applications that do not have application capacity defined this value will be zero.
  - `ApplicationLoadMetricInformation` ApplicationMetricDescription[] — List of application capacity metric description.
    - `Name` string — The name of the metric.
    - `MaximumCapacity` integer — The maximum node capacity for Service Fabric application. This is the maximum Load for an instance of this application on a single node. Even if the capacity of node is greater than this value, Service Fabric will limit the total load of services within the application on each node to this value. If set to zero, capacity for this metric is unlimited on each node. When creating a new application with application capacity defined, the product of MaximumNodes and this value must always be smaller than or equal to TotalApplicationCapacity. When updating existing application with application capacity, the product of MaximumNodes and this value must always be smaller than or equal to TotalApplicationCapacity.
    - `ReservationCapacity` integer — The node reservation capacity for Service Fabric application. This is the amount of load which is reserved on nodes which have instances of this application. If MinimumNodes is specified, then the product of these values will be the capacity reserved in the cluster for the application. If set to zero, no capacity is reserved for this metric. When setting application capacity or when updating application capacity; this value must be smaller than or equal to MaximumCapacity for each metric.
    - `TotalApplicationCapacity` integer — The total metric capacity for Service Fabric application. This is the total metric capacity for this application in the cluster. Service Fabric will try to limit the sum of loads of services within the application to this value. When creating a new application with application capacity defined, the product of MaximumNodes and MaximumCapacity must always be smaller than or equal to this value.

## Other responses

- `204` — An empty response is returned if the specified applicationId is not found in the cluster.
- `default` — The detailed error response.
