Create an alert
Start with a name, the measure to evaluate, and an optional Group by dimension. Grouping evaluates the selected measure for each group; choosing Single total evaluates one total instead. You can also add filters to narrow the events the alert evaluates. Only plain entity dimensions are available for grouping. Time, JSON, derived, and grain grouping are not supported.Choose a condition
A threshold alert fires when a measured value matches its operator and value. A comparison alert checks whether a single total has increased or decreased by the chosen percentage, so remove grouping before selecting it.
Set the schedule
Evaluate every controls how often the alert runs. You can choose 1, 5, or 15 minutes; 1, 6, or 12 hours; or 1 day. Look-back window is how many minutes of data each evaluation looks at. It must be at least as long as the evaluation interval and at most 1 day (1,440 minutes).Delivery
A webhook URL is required for every alert. Carbon sends a JSON payload when an alert breaches, resolves, or becomes broken.
Use Test beside the webhook URL to send the current preview payload with
test: true. The test is marked as a test delivery and does not create alert history.
Statuses
Edit a broken alert to reset its evaluation and resume it.
Run history
Each alert keeps a run history of its most recent 50 evaluations. A run can be OK, Breach, Error, or Insufficient data. Select a run to open its details, including the evaluation time, delivery state, error when present, changed groups, and the observed-value preview.Each space can have up to 20 alerts.
