What statement is true about Splunk alerts?

Alerts in Splunk are a powerful feature that allow users to monitor their data for specific conditions and respond proactively. The correct statement highlights that alerts can be configured based on searches performed either on a set schedule or in real-time. This flexibility means that you can tailor alerting to match the needs of your organization, whether you need to monitor data continuously as it comes in or prefer to check it at regular intervals.

The ability to set alerts for both scheduled and real-time searches enables users to be alerted of critical incidents or anomalies as they happen, which is essential for timely response. This aspect of Splunk's alerting system allows organizations to effectively monitor their infrastructure, applications, and user behavior.

The other statements restrict the capabilities of alerts. Some mention that alerts only send email notifications, which is incomplete as Splunk supports various notification methods, including webhook integrations and other alert actions. Others imply that alerts can only use cron jobs for scheduling, which misconstrues the broader scope of scheduling options available within Splunk. Finally, suggesting that alerts run exclusively as real-time searches overlooks the important function of scheduled searches, which can be equally valuable for monitoring purposes.
