Activator editor

What this editor does

An Activator (Reflex) detects conditions on real-time data and fires actions — Teams, email, webhook, SMS, Logic App, pipeline, notebook, or Power Automate. In Loom the DEFAULT rule source is an Eventhouse / KQL database on Azure Data Explorer: the rule's KQL evaluates against real stream data via the ADX-native Activator runtime — no Microsoft Fabric required. Log Analytics KQL and Event Hub sources are alternatives backed by Azure Monitor scheduled-query alerts. The editor has two tabs: Rules and Run history.

Getting started

  1. Pick a source — The default source is Eventhouse / KQL Database (ADX): pick the database and table from the live pickers (resolved from the shared ADX cluster). KQL query (Log Analytics) and Event Hub are alternative sources.
  2. Define the trigger — Use the guided condition builder (property, operator, threshold) against the selected table, or supply a verbatim KQL query — the rule fires when it returns rows.
  3. Pick the action — Choose a Teams notification, email, webhook, SMS, Logic App, pipeline run, notebook, or Power Automate flow — delivered through a real Azure Monitor action group.
  4. Evaluate and watch historyTrigger / Preview evaluates ADX rules on demand against real Eventhouse data; set LOOM_ADX_ALERT_SCOPE (the ADX cluster resource id, with the alert identity granted Database Viewer) for hands-off scheduled evaluation. Log Analytics rules evaluate continuously via Azure Monitor. The Run history tab lists fired alerts.

Tip: Author rule with Copilot drafts the KQL from a plain-English description, suggests a threshold from real history, and creates the rule after you approve.
