    • Advanced alert filters reduce noise by dropping alerts that do not indicate a significant issue.

    You use an advanced log alert filter to determine whether to drop or allow an alert. For example, you can define a filter that drops (discards) alerts that come from particular sources or alerts for anomalies that do not cross a specified threshold.

    Some examples of the actions that advanced filters can enable:
    • Alert only on anomalies shared across multiple hosts.
    • Do not alert on anomalies that happen outside of working hours.
    • Do not alert if the anomaly amplitude does not cross the specified threshold.
    • Alert only on anomalies that are part of a correlation.
