Which action triggers an event when a Synthetic PoP is uninstalled?

IBM Instana provides a set of pre-configured, built-in events to monitor the health of its components. The "Synthetic pop status" is a specific built-in event designed to track the state of a Synthetic Point of Presence (PoP). When a PoP is uninstalled, it stops sending heartbeats to the Instana backend. The system automatically detects this lack of communication and triggers the "Synthetic pop status" event to report the PoP as offline. This process is fully automated and requires no manual intervention or custom configuration.

A. A specific built-in event exists for this purpose, making a custom offline rule redundant for this standard scenario.

B. The event triggering is an automated health-checking function within Instana; it does not require manual user action.

D. The default behavior of the "Synthetic pop status" event is sufficient to detect an uninstalled PoP; no modifications are necessary.

1. IBM Instana Documentation, "Built-in event reference": This document lists and describes the events that are available out-of-the-box with Instana. It details the "Synthetic PoP status" event, which is triggered when a Synthetic PoP is offline. Uninstallation is a primary cause for a PoP to go offline.
