The following classes are available globally.
FIRHTTPMetric object can be used to make the SDK record information about a HTTP network request.
class HTTPMetric : NSObject, PerformanceAttributable
This class allows you to configure the Firebase Performance Reporting SDK. It also provides the interfaces to create timers and enable or disable automatic metrics capture.
This SDK uses a Firebase Instance ID token to identify the app instance and periodically sends data to the Firebase backend. (see
[FIRInstanceID getIDWithHandler:]). To stop the periodic sync, call
[FIRInstanceID deleteIDWithHandler:]and either disable this SDK or set FIRPerformance.dataCollectionEnabled to NO.
class Performance : NSObject
FIRTrace objects contain information about a “Trace”, which is a sequence of steps. Traces can be used to measure the time taken for a sequence of steps. Traces also include “Counters”. Counters are used to track information which is cumulative in nature (e.g., Bytes downloaded). Counters are scoped to an FIRTrace object.
