We can use real-time warnings that occur once per outcome or only if those conditions are met within a limited time span of rolling. In circumstances where immediate monitoring and responses are relevant, they can be useful. Real-time alerts constantly scan for incidents. The admin configures the warning to activate if search results do not exist. He schedules the alert to look every three hours for events from the host.

An admin generates a scheduled warning to check if no data has been submitted to the Splunk platform by a given host in the last few hours.

The admin generates a scheduled warning which searches every hour for 404 errors and triggers if there are over 100 results.

An administrator wants to monitor how often the users follow a bad link to the 404 error page.

She configures the warning to activate if the result numbers are below 500.

The administrator schedules the warning to try sales events at 23:00 each day. A retailer admin creates a scheduled alert for monitoring the performance of the sales.

An online retailer is targeting 500 sales daily.

If immediate or real-time monitoring is not a priority, a scheduled alert is useful. Use a scheduled alert to search for events regularly, and monitor if they meet specific conditions. The following scenarios show various use cases for alert and trigger types. Depending on the events we are monitoring, we may need a real-time alert that triggers with each result or a scheduled alert that triggers only if results meet certain conditions. Once we select a scheduled or real-time alert, we can configure how the alert will trigger outcomes. For example, when there are more than 10 results in a five-minute window, a real-time alert can trigger. Rolling time window: Specify conditions within a rolling time window for triggering the alert based on the result or result field counts. Specify a time span and optional suppression field values. Per-result: Every time there is a search result, triggers. When in any case, a set of search results meets the trigger conditions in Splunk, then the alert can trigger for each of the results once. Specify the warning cause conditions depending on the outcome, or the response area counts.

Pick from the timing options available, or use a cron expression to schedule the hunt. Here is a comparison of the alerts in schedule and in real-time. We can customize timing, activation, and other actions for either type of alarm according to the scenario. Definitions of type of alert are based on the timing of the search alert. Two types of alerts exist, scheduled and in real-time. We may customize the frequency and type of warning action. An alert action can notify us of a triggered alert and can help us get started to respond.

When an alert triggers, one or more alert actions may be initialized. We can also throttle an alert to control how quickly following an initial alert can trigger the next alert.Īlert Action: What happens in the Splunk environment when the alert triggers?
