Changelog History

  • v1.0.0 Changes

    ๐Ÿš€ There are no changes in the 1.0.0 release - it marks the stability of the API.

  • v0.4.3 Changes

    This release improves the telemetry:span/3 function by adding the telemetry_span_context metadata ๐Ÿ“‡ to all span events. The new metadata enables correlating span events that belong to the same span.

    โž• Added

    • Added telemetry_span_context metadata to all events emitted by telemetry:span/3.
  • v0.4.2 Changes

    โž• Added

    • โž• Added the telemetry:span/3 function.
  • v0.4.1 Changes

    ๐Ÿš€ Apart from the code changes listed below, this release includes a few improvements ๐Ÿ“š to the documentation.

    ๐Ÿ”„ Changed

    • Calls to execute/3 when telemetry application is not started no longer cause an error.
  • v0.4.0 Changes

    February 09, 2019

    A single event value has been replaced by a map of measurements. Now it is up to the consumer of the ๐Ÿ›ฐ event to decide what part of the payload is important. This is useful in cases where event indicates that a thing happened but there are many properties describing it. For example, a database query event may include total time, decode time, wait time and other measurements.

    ๐Ÿ”„ Changed

    • execute/3 now accepts a map of measurements instead of event value

    ๐Ÿ—„ Deprecated

    • :telemetry.execute/3 with an event value in favour of :telemetry.execute/3 with a map of measurements. If the event value is provided, it is put in a map under a :value key and provided as measurements to a handler function.
  • v0.3.0 Changes

    December 31, 2018

    ๐Ÿš€ This release marks the conversion from Elixir to Erlang. This is a breaking change, but the benefits largely surpass the drawbacks - Telemetry core can now be used by all projects running on the BEAM, regardless of the language they're written in.

    โž• Added

    • Added :telemetry.handler/0, :telemetry.handler_function/0 and :telemetry.handler_config/0 types.

    ๐Ÿ”„ Changed

    • The library has been rewritten to Erlang. In Elixir, :telemetry module has to be used in place of Telemetry. In Erlang, telemetry module has to be used in place of 'Elixir.Telemetry';
    • :telemetry.list_handlers/1 returns a list of maps (of type :telemetry.handler/0) instead of a list of tuples;
    • :telemetry.attach/4 and :telemetry.attach_many/4 replaced the 5-arity versions and now accept an anonymous function for the handler function instead of a module and function name.

    โœ‚ Removed

    • โœ‚ Removed :telemetry.attach/5 and :telemetry.attach_many/5 - 4-arity versions need to be used now instead.
  • v0.2.0 Changes

    October 12, 2018

    ๐Ÿš€ The main point of this release is to mark base Telemetry API as stable, so that other libraries can rely on it without worrying about backwards compatibility.

    โœ‚ Removed

    • โœ‚ Removed Telemetry.attach/4 and Telemetry.attach_many/4 - the handler config is now required.

    ๐Ÿ›  Fixed

    • ๐Ÿ›  Fixed type specs which were producing Dialyzer errors.
  • v0.1.0 Changes

    August 13, 2018

    ๐Ÿš€ First release of Telemetry library.
