Telemetry is a mechanism used to capture metrics in an application, to later store the data locally or upload it to a server for statistical analysis.

Examples of usage:

  • capturing the speed of an operation;
  • finding out if users are actually using a feature;
  • finding out how the duration of a session;
  • determine the operating system on which the application is executed;
  • determining the configuration of the application;
  • capturing the operations that slow down the application;
  • determining the amount of I/O performed by the application;
  • ...

The main abstraction used by this library is the Histogram. Each Histogram serves to capture a specific measurement. Measurements can then be exported, so that applications can save them to disk or upload them to a server. Several types of Histograms are provided, suited to distinct kinds of measures.
