Returns BrowserPerformanceClient
Overrides PerformanceClient.constructor
- Defined in msal-browser/src/telemetry/BrowserPerformanceClient.ts:26

Methods

addFields

addFields(fields, correlationId): void
Saves extra information to be emitted when the measurements are flushed
Parameters
- fields: {
  [key: string]: {} | undefined;
  }
  - [key: string]: {} | undefined
- correlationId: string
Returns void
Implementation of IPerformanceClient.addFields

Inherited from PerformanceClient.addFields
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:130

addPerformanceCallback

addPerformanceCallback(callback): string
Registers a callback function to receive performance events.
Parameters
- callback: PerformanceCallbackFunction
Returns string
Implementation of IPerformanceClient.addPerformanceCallback

Inherited from PerformanceClient.addPerformanceCallback
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:170

addQueueMeasurement

addQueueMeasurement(eventName, correlationId?, queueTime?, manuallyCompleted?): void
Calculates and adds queue time measurement for given performance event.
Parameters
- eventName: string
- Optional correlationId: string
- Optional queueTime: number
- Optional manuallyCompleted: boolean
  
  indicator for manually completed queue measurements
Returns void
Implementation of IPerformanceClient.addQueueMeasurement

Overrides PerformanceClient.addQueueMeasurement
- Defined in msal-browser/src/telemetry/BrowserPerformanceClient.ts:190

calculateQueuedTime

calculateQueuedTime(preQueueTime, currentTime): number
Calculates the difference between current time and time when function was queued. Note: It is possible to have 0 as the queue time if the current time and the queued time was the same.
Parameters
- preQueueTime: number
- currentTime: number
Returns number
Implementation of IPerformanceClient.calculateQueuedTime

Inherited from PerformanceClient.calculateQueuedTime
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:95

discardMeasurements

discardMeasurements(correlationId): void
Removes measurements for a given correlation id.
Parameters
- correlationId: string
Returns void
Implementation of IPerformanceClient.discardMeasurements

Inherited from PerformanceClient.discardMeasurements
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:157

emitEvents

emitEvents(events, correlationId?): void
Emits events to all registered callbacks.
Parameters
- events: PerformanceEvent[]
- Optional correlationId: string
Returns void
Implementation of IPerformanceClient.emitEvents

Inherited from PerformanceClient.emitEvents
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:184

endMeasurement

endMeasurement(event, measurement?): null | PerformanceEvent
Stops measuring the performance for an operation. Should only be called directly by PerformanceClient classes, as consumers should instead use the function returned by startMeasurement. Adds a new field named as "[event name]DurationMs" for sub-measurements, completes and emits an event otherwise.
Parameters
- event: PerformanceEvent
- Optional measurement: IPerformanceMeasurement
Returns null | PerformanceEvent
Implementation of IPerformanceClient.endMeasurement

Inherited from PerformanceClient.endMeasurement
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:124

generateId

generateId(): string
Generates and returns a unique id, typically a guid.

Returns string

Abstract
Implementation of IPerformanceClient.generateId

Overrides PerformanceClient.generateId
- Defined in msal-browser/src/telemetry/BrowserPerformanceClient.ts:52

getPreQueueTime

getPreQueueTime(eventName, correlationId): number | void
Gets map of pre-queue times by correlation Id
Parameters
- eventName: string
- correlationId: string
Returns number | void
Inherited from PerformanceClient.getPreQueueTime
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:86

incrementFields

incrementFields(fields, correlationId): void
Increment counters to be emitted when the measurements are flushed
Parameters
- fields: {
  [key: string]: number | undefined;
  }
  
  {string[]}
  - [key: string]: number | undefined
- correlationId: string
  
  {string} correlation identifier
Returns void
Implementation of IPerformanceClient.incrementFields

Inherited from PerformanceClient.incrementFields
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:138

removePerformanceCallback

removePerformanceCallback(callbackId): boolean
Removes a callback registered with addPerformanceCallback.
Parameters
- callbackId: string
Returns boolean
Implementation of IPerformanceClient.removePerformanceCallback

Inherited from PerformanceClient.removePerformanceCallback
- Defined in msal-common/dist/telemetry/performance/PerformanceClient.d.ts:177

setPreQueueTime

setPreQueueTime(eventName, correlationId?): void
Adds pre-queue time to preQueueTimeByCorrelationId map.
Parameters
- eventName: PerformanceEvents
- Optional correlationId: string
Returns void
Implementation of IPerformanceClient.setPreQueueTime

Overrides PerformanceClient.setPreQueueTime
- Defined in msal-browser/src/telemetry/BrowserPerformanceClient.ts:139

startMeasurement

startMeasurement(measureName, correlationId?): InProgressPerformanceEvent
Starts measuring performance for a given operation. Returns a function that should be used to end the measurement. Also captures browser page visibilityState.
Parameters
- measureName: string
- Optional correlationId: string
Returns InProgressPerformanceEvent
Implementation of IPerformanceClient.startMeasurement

Overrides PerformanceClient.startMeasurement
- Defined in msal-browser/src/telemetry/BrowserPerformanceClient.ts:99
