Short answer: yes—you can limit Slack alerts to just “today,” and also reduce noise when you’ve missed a day. What’s happening: - Elementary sends all pending alerts that haven’t been sent yet when you run edr monitor. If you skip a day, you’ll get yesterday’s + today’s pending alerts in the next run.

[[Days-back tip](https://slack.com/archives/C02CTC89LAX/p1663241888773889); [Days-back meaning](https://slack.com/archives/C02CTC89LAX/p1669159603059669)] - Run edr monitor after every dbt invocation (dbt run/test) so you don’t accumulate previous-day pending alerts. [[Run after dbt](https://slack.com/archives/C02CTC89LAX/p1685463491192549); [Pending vs sent](https://slack.com/archives/C02CTC89LAX/p1685463491192549)] - If you want a longer history in the HTML report but only “today” in Slack, run them separately with different windows: - edr monitor --days-back 0 - edr monitor send-report --days-back 7 [[Separate windows](https://slack.com/archives/C02CTC89LAX/p1669159603059669)] Extra noise controls: - Group multiple alerts into a single Slack message with --group-alerts-threshold (available in package v0.16.2+). [[Group alerts](https://slack.com/archives/C02CTC89LAX/p1739838766535989)] - Use alert_suppression_interval to “snooze” recurring alerts during testing. [[Suppress interval](https://slack.com/archives/C02CTC89LAX/p1739838766535989)] If you still see more Slack messages than expected for “today,” double‑check: - The exact --days-back used in the edr monitor command that sends Slack alerts. - That edr monitor isn’t being skipped or run less frequently than dbt, which would leave more pending alerts to send later.
