Interpreting Results

Consumer Health

Check if consumers are stuck by comparing exception time vs activity times:

• last_exception_time >= last_poll_time OR last_exception_time >= last_commit_time → consumer stuck on error, not progressing
• Otherwise → consumer healthy

The exceptions column is a tuple of arrays with matching indices — exceptions.time[-1] and exceptions.text[-1] give the most recent error.
