Telemetry Event Reference

Telemetry events are only reported if telemetry is enabled. A detailed explanation on the reasoning behind collecting optional telemetry events can be found in our telemetry documentation.

Model Training#

Training Started#

backend A training of a Rasa machine learning model got started. The event provides information on aggregated training data statistics. Event properties:

• language (string): Language model is trained with, e.g. 'en'.
• training_id (string): Generated unique identifier for this training.
• type (string): Type of model trained, either 'nlu', 'core' or 'rasa'.
• pipeline (undefined): List of the pipeline configurations used for training.
• policies (array): List of the policy configurations used for training.
• num_intent_examples (integer): Number of NLU examples.
• num_entity_examples (integer): Number of entity examples.
• num_actions (integer): Number of actions defined in the domain.
• num_templates (integer): Number of templates or responses defined in the domain.
• num_conditional_response_variations (integer): Number of conditional response variations defined in the domain.
• num_slots (integer): Number of slots defined in the domain.
• num_forms (integer): Number of forms defined in the domain.
• num_intents (integer): Number of intents defined in the domain.
• num_entities (integer): Number of entities defined in the domain.
• num_story_steps (integer): Number of story steps available.
• num_lookup_tables (integer): Number of different lookup tables.
• num_synonyms (integer): Total number of entity synonyms defined.
• num_regexes (integer): Total number of regexes defined.
• is_finetuning (boolean): True if a model is trained by finetuning an existing model.

Training Completed#

backend The training of a Rasa machine learning model finished. The event provides information about the resulting model. Event properties:

• training_id (string): Generated unique identifier for this training. Can be used to join with 'Training Started'.
• type (string): Type of model trained, either 'nlu', 'core' or 'rasa'.
• runtime (integer): The time in seconds it took to train the model.

Model Testing#

Model Core Tested#

backend Triggered when a Core model is getting tested. Event properties:

• project (string,null): Fingerprint of the project the tested model got trained in.
• num_story_steps (integer): Number of story steps used for testing
• end_to_end (boolean): Indicates if tests are running in end-to-end mode, testing message handling and dialogue handling at the same time

Model NLU Tested#

backend Triggered when an NLU model is getting tested. Event properties:

• num_intent_examples (integer): Number of NLU examples.
• num_entity_examples (integer): Number of entity examples.
• num_lookup_tables (integer): Number of different lookup tables.
• num_synonyms (integer): Total number of entity synonyms defined.
• num_regexes (integer): Total number of regexes defined.

Model Serving#

Interactive Learning Started#

backend Triggered when an interactive learning session got started. Event properties:
