Name Type Required Location
applicationId string Yes Path
api-version string Yes Query

DeployedApplicationsHealthStateFilter integer No Query
ServicesHealthStateFilter integer No Query
ExcludeHealthStatistics boolean No Query
timeout integer (int64) No Query

applicationId

Type: string
Required: Yes

The identity of the application. This is typically the full name of the application without the 'fabric:' URI scheme. Starting from 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.

api-version

Type: string
Required: Yes
Default: 6.0

The version of the API. This parameter is required and its value must be '6.0'.

Service Fabric REST API version is based on the runtime version in which the API was introduced or was changed. Service Fabric runtime supports more than one version of the API. This is the latest supported version of the API. If a lower API version is passed, the returned response may be different from the one documented in this specification.

Additionally the runtime accept any version that is higher than the latest supported version up to the current version of the runtime. So if the latest API version is 6.0, but if the runtime is 6.1, in order to make it easier to write the clients, the runtime will accept version 6.1 for that API. However the behavior of the API will be as per the documented 6.0 version.

EventsHealthStateFilter

Type: integer
Required: No
Default: 0

Allows filtering the collection of HealthEvent objects returned based on health state. The possible values for this parameter include integer value of one of the following health states. Only events that match the filter are returned. All events are used to evaluate the aggregated health state. If not specified, all entries are returned. The state values are flag-based enumeration, so the value could be a combination of these values, obtained using the bitwise 'OR' operator. For example, If the provided value is 6 then all of the events with HealthState value of OK (2) and Warning (4) are returned.

  • Default - Default value. Matches any HealthState. The value is zero.
  • None - Filter that doesn't match any HealthState value. Used in order to return no results on a given collection of states. The value is 1.
  • Ok - Filter that matches input with HealthState value Ok. The value is 2.
  • Warning - Filter that matches input with HealthState value Warning. The value is 4.
  • Error - Filter that matches input with HealthState value Error. The value is 8.
  • All - Filter that matches input with any HealthState value. The value is 65535.

DeployedApplicationsHealthStateFilter

Type: integer
Required: No
Default: 0

Allows filtering of the deployed applications health state objects returned in the result of application health query based on their health state. The possible values for this parameter include integer value of one of the following health states. Only deployed applications that match the filter will be returned. All deployed applications are used to evaluate the aggregated health state. If not specified, all entries are returned. The state values are flag-based enumeration, so the value could be a combination of these values, obtained using bitwise 'OR' operator. For example, if the provided value is 6 then health state of deployed applications with HealthState value of OK (2) and Warning (4) are returned.

  • Default - Default value. Matches any HealthState. The value is zero.
  • None - Filter that doesn't match any HealthState value. Used in order to return no results on a given collection of states. The value is 1.
  • Ok - Filter that matches input with HealthState value Ok. The value is 2.
  • Warning - Filter that matches input with HealthState value Warning. The value is 4.
  • Error - Filter that matches input with HealthState value Error. The value is 8.
  • All - Filter that matches input with any HealthState value. The value is 65535.

ServicesHealthStateFilter

Type: integer
Required: No
Default: 0

Allows filtering of the services health state objects returned in the result of services health query based on their health state. The possible values for this parameter include integer value of one of the following health states. Only services that match the filter are returned. All services are used to evaluate the aggregated health state. If not specified, all entries are returned. The state values are flag-based enumeration, so the value could be a combination of these values, obtained using bitwise 'OR' operator. For example, if the provided value is 6 then health state of services with HealthState value of OK (2) and Warning (4) will be returned.

  • Default - Default value. Matches any HealthState. The value is zero.
  • None - Filter that doesn't match any HealthState value. Used in order to return no results on a given collection of states. The value is 1.
  • Ok - Filter that matches input with HealthState value Ok. The value is 2.
  • Warning - Filter that matches input with HealthState value Warning. The value is 4.
  • Error - Filter that matches input with HealthState value Error. The value is 8.
  • All - Filter that matches input with any HealthState value. The value is 65535.

ExcludeHealthStatistics

Type: boolean
Required: No
Default: false

Indicates whether the health statistics should be returned as part of the query result. False by default. The statistics show the number of children entities in health state Ok, Warning, and Error.

timeout

Type: integer (int64)
Required: No
Default: 60
InclusiveMaximum: 4294967295
InclusiveMinimum: 1

The server timeout for performing the operation in seconds. This timeout specifies the time duration that the client is willing to wait for the requested operation to complete. The default value for this parameter is 60 seconds.
