When you instrument your application using the Honeycomb OpenTelemetry Swift SDK, spans automatically include a standard set of attributes. These attributes provide essential context about the environment, runtime, device, and SDK versions–helping you understand where and how telemetry is being generated.
Every span includes some core attributes.
honeycomb.distro.runtime_version: Operating system version on the device.honeycomb.distro.version: Version of the Honeycomb SDK in use.os.description: String describing the OS version, build ID, and SDK level.os.name: OS name. Always iOS for iOS devices.os.type: OS type. Always darwin on Apple platforms.os.version: Current OS Version.service.name: Name of your application. Set via setServiceName() or inferred from your bundle.service.version: Version of your application. Set via setServiceVersion(). Defaults to being inferred from your bundle.telemetry.distro.name: Name of the Honeycomb SDK in use. Always honeycomb-opentelemetry-swift for the Honeycomb OpenTelemetry Swift SDK.telemetry.distro.version: Version of the Honeycomb SDK in use.telemetry.sdk.language: Coding language for the Honeycomb SDK in use. Always swift for the Honeycomb OpenTelemetry Swift SDK.telemetry.sdk.name: Name of the telemetry SDK used to generate telemetry data. Always opentelemetry for the Honeycomb OpenTelemetry Swift SDK.telemetry.sdk.version: Version of the OpenTelemetry SDK in use. If your application uses UIKit, the SDK also includes device-level attributes from UIDevice. These give insight into the physical device running your application.
device.id: Vendor-specific device identifier. (UIDevice.identifierForVendor)device.name: Name of the device. (UIDevice.name)device.systemName: Operating system (OS) name. (UIDevice.systemName)device.systemVersion: OS version string. (UIDevice.systemVersion)device.model: Device model name. (UIDevice.model)device.localizedModel: Localized version of the device model. (UIDevice.localizedModel)device.userInterfaceIdiom: Type of interface the device uses. (UIDevice.userInterfaceIdiom)device.isMultitaskingSupported: Indicates whether the device supports multitasking. (UIDevice.isMultitaskingSupported)device.orientation: Current device orientation. (UIDevice.orientationdevice.isLowPowerModeEnabled: Indicates whether Low Power Mode is currently active. (UIDevice.isLowPowerModeEnabled)device.isBatteryMonitoringEnabled: Indicates whether battery monitoring is turned on. (UIDevice.isBatteryMonitoringEnabled)device.batteryLevel: Battery level. Included only if UIDevice.current.batteryStateAttributesEnabled is set to true. (UIDevice.batteryLevel)device.batteryState: Battery state. Included only if UIDevice.current.batteryStateAttributesEnabled is set to true. (UIDevice.batteryState) If MetricKit is available and you’ve enabled MetricKit instrumentation, the SDK adds system performance and behavior metrics. These help identify performance bottlenecks, power usage trends, and device conditions.
