ErrorTracker.Telemetry (ErrorTracker v0.6.0)

Telemetry events of ErrorTracker.

ErrorTracker emits some events to allow third parties to receive information of errors and occurrences stored.

Those occur during the life cycle of an error:

[:error_tracker, :error, :new]: is emitted when a new error is stored and no previous occurrences were known.
[:error_tracker, :error, :resolved]: is emitted when a new error is marked as resolved on the UI.
[:error_tracker, :error, :unresolved]: is emitted when a new error is marked as unresolved on the UI or a new occurrence is registered, moving the error to the unresolved state.

There is only one event emitted for occurrences:

[:error_tracker, :occurrence, :new]: is emitted when a new occurrence is stored.

Each event is emitted with some measures and metadata, which can be used to receive information without having to query the database again:

event	measures	metadata
`[:error_tracker, :error, :new]`	`:system_time`	`:error`
`[:error_tracker, :error, :unresolved]`	`:system_time`	`:error`
`[:error_tracker, :error, :resolved]`	`:system_time`	`:error`
`[:error_tracker, :occurrence, :new]`	`:system_time`	`:occurrence`, `:error`, `:muted`

The metadata keys contain the following data:

:error - An %ErrorTracker.Error{} struct representing the error.
:occurrence - An %ErrorTracker.Occurrence{} struct representing the occurrence.
:muted - A boolean indicating whether the error is muted or not.
