Data Discovery: Execution History and Events

Execution​

For browsing and filtering execution histories, each record represents one execution from one trigger which contains at least one tasks. Each task contains logs (from Logging Agent), trigger payload as well as task result (from Result Agent) from each task.

Click the trigger name to inspect the details, from which you can expand the list of logic and their logs.

execution

See View Execution History in one of the tutorial for more details.

Execution Status​

● Complete

An execution, task or logic had completed execution without errors or timeout.

● In Progress

An execution is still running due to execution of one of the task or logic has not yet completed and timeout hasn't been reached.

● Timeout

Execution time of one of the task had exceeded the data process' timeout limit (default: 180 seconds).

● Execution Error

For an execution, it indicates one of the task had reported Timeout, Complete with Error or System Error.

● Complete with Error

  1. For a logic, it indicates an error had been thrown in run() (and handleError() had been invoked).

  2. For a task, it indicates a logic had reported Complete with Error (and the aggregator logic had invoked handleError() and may return a different task result).

● System Error

  1. For a logic, it indicates the logic cannot be executed due to syntax errors, bundle errors (for native logic) or handleError() had also thrww an error.

  2. For a task, it indicates one of the logic had reported System Error and stopped the task (no task results available).

● Not Execute

Logic had skipped execution due to one previous logic in the task had reported System Error.

Event​

For browsing and filtering events (emitted by Event Store Agent).

Each event - a persistent "log" with metadata including label name, source DID, target DID, meta payload and time/task-related fields - can be queried for various purposes.

See the following tutorials of how to emit and inspect events/data lineages:

Event Lineage Graph​

After filtering events, you can click Event Lineage Graph to inspect the graphical result of data lineage:

If you click an event by its label name or source/target DID, you will be switched to the Label Name or DID panels.
