GET /Services/{serviceId}/$/GetHealth?api-version=6.0&EventsHealthStateFilter={EventsHealthStateFilter}&PartitionsHealthStateFilter={PartitionsHealthStateFilter}&ExcludeHealthStatistics={ExcludeHealthStatistics}&timeout={timeout}

Parameters

Name Type Required Location
serviceId string Yes Path
api-version string Yes Query
EventsHealthStateFilter integer No Query
PartitionsHealthStateFilter integer No Query
ExcludeHealthStatistics boolean No Query
timeout integer (int64) No Query

serviceId

Type: string
Required: Yes

The identity of the service. This ID is typically the full name of the service without the 'fabric:' URI scheme. Starting from version 6.0, hierarchical names are delimited with the "~" character. For example, if the service name is "fabric:/myapp/app1/svc1", the service identity would be "myapp~app1~svc1" in 6.0+ and "myapp/app1/svc1" 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.

PartitionsHealthStateFilter

Type: integer
Required: No
Default: 0

All partitions 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 value obtained using bitwise 'OR' operator. For example, if the provided value is 6 then health state of partitions 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.
