Alerts

Automated alerts are triggered when radio streams hosted on our platform experience downtime due to the incoming audio signal being unavailable or silent. These alerts can inform broadcasters when there may be an issue with their equipment or internet connection.

This page allows managements of these alerts, including:

• Enabling or disabling alerts,
• Changing the "downtime" period before triggering an alert,
• Adding emails or Slack endpoints where the alerts will be sent to,
• Listing all current alert endpoints configured for the stream.

Example of default settings:

Alerts

Alerts are triggered when the condition (offline or silence) has been active for a configurable interval (default 10 minutes).

Most offline alerts are caused by temporary internet routing or networking issues that auto-resolve. A waiting threshold is applied to reduce false positives; alerts should only trigger when there may be an issue that requires manual intervention to resolve.

Short outages

Short frequent outages below the threshold won't trigger alerts and can be "invisible" to broadcasters but still cause significant user dissatisfaction. We recommend publishers also monitor the uptime heatmap on the Streaming Monitor page, which highlights the general availability of the incoming stream.

Silence (dead air) detection

The incoming stream audio volume is measurement in per minute averages using Loudness Units relative to Full Scale (LUFS). Any average value below -40 LUFS is considered dead air.
