0.4.0

Telemetry Poller has been rewritten in Erlang so it can be used by the overall Erlang community. Therefore, the Telemetry.Poller module must now be accessed as telemetry_poller. A new process_info measurement has also been added and the vm_measurements and measurements keys have been merged into a single measurements key for simplicity.

Added

• :process_info measurement

• vm_measurements and measurements have been merged into measurements
• Telemetry.Poller has been rewritten to telemetry_poller

0.3.0

This release marks the upgrade to Telemetry 0.4.0. This means that Poller measurements can emit a map of values now instead of a single one, making it less "noisy" when it comes to number of emitted events.

All specific memory measurements have been replaced with a single :memory measurement sending all the values that were emitted by old measurements at once.

:run_queue_lengths VM measurement has been removed for now, as we believe that as detailed data as it provided is not necessary to effectively debug the system. :total_run_queue_lengths VM measurement has been changed so that it reports a :total length of run queues, length of :cpu run queues (including dirty CPU run queue), and length of (dirty) :io run queue.

added-4

Added

• :memory VM measurement reporting all the data returned by :erlang.memory/0 call.

changed-3

Changed

• :total_run_queue_lengths VM measurement is reporting a :total, :cpu and :io run queue lengths now. See documentation for more details.

removed

Removed

• :total_memory, :atom_memory, :atom_used_memory, :processes_memory, :processes_used_memory, :binary_memory, :ets_memory, :code_memory and :system_memory VM measurements have been removed. Please use the :memory measurement now instead.

0-2-0

0.2.0

added-5

Added

• Added :total_run_queue_lengths and :run_queue_lengths memory measurements;

changed-4

Changed

• :total_run_queue_lengths is now included in the set of default VM measurements;
• A default Poller process, with a default set of VM measurements, is started when :telemetry_poller application starts (configurable via :telemetry.poller, :default application environment).
• VM measurements are now provided to Poller's :vm_measurements option. Passing atom :default to this option makes the Poller use a default set of VM measurements;
• Telemetry has been upgraded to version 0.3, meaning that VM measurements now use this version to emit the events.

removed-1

Removed

• Telemetry.Poller.vm_measurements/0 function has been removed in favor of :vm_measurements option.

fixed-1

Fixed

• Fixed the type definition of Telemetry.Poller.measurement/0 type - no Dialyzer warnings are emitted when running it on the project.

0-1-0

0.1.0

added-6

Added

• The Poller process periodically invoking registered functions which emit Telemetry events. It supports VM memory measurements and custom measurements provided as MFAs.
