According to IBM Instana Observability (v1.0.307 and earlier), stanctl cluster backup is a built-in utility and command-line tool to back up system state and operational data from an Instana cluster. The verified procedure reads: "stanctl cluster backup saves configuration, operational state, and selected monitoring data into an archive file located in the current working directory." This archive is designed for disaster recovery and migration, containing all crucial files needed for restoring Instana to a consistent state. Disk snapshots (A) are separate and handled by storage appliances. Option B describes pre-backup preparation rather than the actual result. Remote backup (C) operations require remote execution configuration and are not part of the default cluster backup. Thus, D is correct as per documentation, which emphasizes bringing together all cluster backup data in a portable .tar or .zip archive for safe storage or transfer.

IBM Instana integrates natively with Prometheus to unify metric ingestion without disrupting existing telemetry setups. The configuration parameter remote_write enables this linkage. The official documentation states: "The remote_write configuration enables Prometheus to send data to Instana, where those metrics are displayed either as Prometheus entities or merged into process custom metrics." Instead of storing them only within Prometheus, Instana pulls remote_write relay feeds to create comprehensive, unified metrics views in its dashboard. This approach avoids duplicate monitoring systems and allows alerting across both Prometheus and Instana data seamlessly. The parameter does not configure outbound writing by Instana back into Prometheus—data always flows from Prometheus to Instana in this architecture. This integration respects Prometheus scraping principles yet centralizes analysis within Instana, achieving correlation between imported numerical time-series values and native metrics at the application or process layer.

The dashboard permissions model in Instana ensures secure, user-specific management of visual analytics content. IBM confirms: "By default, dashboards created by a user are private and accessible only to their creator; they can be shared explicitly with other users or teams for viewing or editing." This model supports controlled collaboration while maintaining ownership accountability. The owner may later assign permissions within the UI, typically under the Dashboard Sharing and Permissions option, defining read or write privileges per user or group. Default private scoping avoids accidental data exposure yet allows managed distribution in team settings. Public dashboards may be intentionally created as shared artifacts, but sharing must always be a conscious user action. These principles align with enterprise-grade security requirements described in the Permissions section of the dashboards documentation and remain unchanged across Instana versions.
