Create real-time alerts

Use a real-time alert to monitor events or event patterns as they happen. You can create real-time alerts with per-result triggering or rolling time window triggering. Real-time alerts can be costly in terms of computing resources, so consider using a scheduled alert when possible.

To compare scheduled and real-time alerts, see Alert types. To review scenarios for alert types and triggering, see Alert type and triggering scenarios.

Create a real-time alert with per-result triggering

Real-time alerts with per-result triggering are sometimes known as "per-result alerts". This alert type and triggering use a continuous real-time search to look for events. Each search result triggers the alert.

Caution: If you have a Splunk Enterprise high-availability deployment, use per-result triggering with caution. If a peer is not available, a real-time search does not warn that the search might be incomplete. To avoid this issue, use a scheduled alert

Follow these steps to create a real-time alert with per-result triggering.

  1. Navigate to the Search page in the Search and Reporting app.
  2. Create a search.
  3. Select Save As>Alert.
  4. Enter a title and optional description.
  5. Specify permissions.
  6. Select the Real-time alert type.
  7. Select the Per-Result trigger option.
  8. (Optional) Configure a trigger throttling period.
  9. Select one or more alert actions that should happen when the alert triggers.
  10. Click Save.

Create a real-time alert with rolling window triggering

Real-time alerts with rolling time window triggering are sometimes known as "rolling window alerts". The rolling time window is an interval or increment, such as five minutes. It is not a scheduled time. Because real-time alerts search continuously, the time window applied to events also rolls forward in time.

Use this alert type and triggering when a specific time interval is part of the event pattern you are monitoring in real time. This alert type and triggering are the most resource-demanding alerting option. It can be helpful to consider using another alert type if possible.

Follow these steps to create a real-time alert with rolling window triggering.

  1. Navigate to the Search page in the Search and Reporting app.
  2. Create a search.
  3. Select Save As>Alert.
  4. Enter a title and an optional description.
  5. Specify permissions.
  6. Select the Real-time alert type.
  7. Select one of the available result-based conditions or enter a custom triggering condition. Do not select per-result triggering.
  8. Specify a time interval to add to the triggering condition.
  9. (Optional) Configure a trigger throttling period.
  10. Select one or more alert actions that should happen when the alert triggers.
  11. Click Save.
