When a Playbook fails to fire despite an Alert occurring, the most common and "likely" cause is a mismatch in theTriggerconfiguration logic.

Trigger Precision:X-Play Triggers are precise. If the administrator selected theAlerttrigger, they must select asingle specificAlert Policy (e.g., "Host High Memory"). If the high-severity alert that occurred was "VM High Memory" (a different policy), the Playbook will not trigger, even if both are "High Severity."

Alerts Matching Criteria:To coverallhigh-severity alerts, the administrator must use theAlerts Matching Criteriatrigger and filter by Severity == Critical. If they used the specific "Alert" trigger or configured the criteria incorrectly (e.g., wrong entity type), the system is "working as implemented" (ignoring non-matching events), but the logic does not match the user's intent.

Autopilot (Option C):While X-Play has an Autopilot feature for KPI optimization, it is not a mandatory requirement for standard alert-based remediation playbooks to function.

The image typically shows the distinction between the "Alert" trigger (Select one policy) and "Alerts Matching Criteria" trigger (Select filters like Severity/Entity), illustrating how a configuration error here leads to the issue described in Question 40.

To ensure a Playbook executes at a specific resource threshold (95% Memory), the administrator must link the Playbook to anAlert Policydefined with that specific threshold.

Relationship between Alerts and Playbooks:In Nutanix Intelligent Operations (X-Play), Playbooks are typically event-driven. The most common trigger is theAlerttrigger. The Playbook itself does not define the threshold (e.g., "95%"); rather, it waits for an Alert to fire.

Configuration:The administrator must configure a specific Alert Policy (e.g., "Critical Memory Usage") in Prism Central to trigger when Memory Usage exceeds 95%.

The Solution:By selecting"Change Trigger to be based off Critical Memory Usage Alert"(Option B), the administrator ensures the Playbook reacts specifically to the alert that corresponds to the 95% threshold. If the system was previously alerting at 100%, it implies the Playbook was linked to a different or default policy. Switching the trigger to the correct "Critical" policy (configured for 95%) solves the issue.

Autopilot (Option A):Autopilot is used totuneinfrastructure limits (like adding CPU/Memory) based on KPI targetsaftera playbook runs; it does not trigger the initial remediation playbook itself.

Among the options provided, calm_unique is the standard built-in macro provided by the Self-Service engine.

Purpose:The @@{calm_unique}@@ macro generates a unique, short alphanumeric string at runtime.

Use Case:It is widely used in Blueprints to ensure uniqueness for VM names, hostname prefixes, or other resources that cannot have duplicate identifiers within the infrastructure (e.g., naming a VM Web-@@{calm_unique}@@ to prevent naming collisions).

Other Options:calm_date, calm_generate_uuid, and calm_math are not standard built-in macro names in the Self-Service macro library (though calm_time and calm_now exist for time-based operations).

TheLibrary(specifically theTask Library) is the designated repository in Nutanix Self-Service for creating and managing reusable automation building blocks.

Task Library:This feature allows administrators to define discrete tasks (such as Shell scripts, PowerShell scripts, HTTP requests, or Python scripts) once and store them centrally.

Reusability:These tasks serve as fundamental "building blocks" because they can be imported into multiple Blueprints and Runbooks across different Projects.

Differentiation:

Tasks (Option C):While "Tasks" are the actual units of work, the question askswherethey are created for the purpose of establishing them as foundational, reusable blocks. They are createdin the Library.

Projects (Option B):Projects are logical containers for users, quotas, and environments, not the repository for reusable script definitions.

Thus, theLibraryis the correct location for creating shared automation assets.
