Every alert raised on a run lands here, whether your agent raised it or one of the agent's [threshold rules](/platform/concepts/alert#threshold-rules) did. The tab shows a red count of alerts that are still active, so a run in trouble stands out before you open it.

1. Active now - the alert has been raised and hasn't cleared.

Each alert has a title, a one-line summary, a severity, and the time it was raised. An alert that hasn't cleared is labelled **Active now**. One that has cleared shows the time range between being raised and cleared. Select an alert to open its details, then use **Previous** and **Next** to step through the others.

The details show the alert's payload as a table of fields and values, followed by the alert's history and its ID. A payload can contain [sensitive data](/platform/sensitive-data), which stays hidden until you turn on **Show sensitive information**. When an alert has a long history, the details show only its most recent events.
