Within Instana, action script sensors execute administrative or diagnostic commands in context of the runtime environment that hosts the Instana agent. The current IBM documentation specifies: "Action scripts are executed by the Instana agent process on the monitored host using the permissions and context of that agent." The agent serves as a self-contained runtime capable of executing defined scripts, invoking system-level or application-specific logic safely within its host boundary. This design enhances automation and extensibility while respecting host-level security because the execution does not escalate privileges beyond the agent’s service account. Instana ensures that scripts running within the agent context inherit its environment variables and operational limits, guaranteeing consistency and preventing user-specific execution inconsistencies. Other answer options (service agent, container, or logged-in user) do not reflect the actual architectural control documented by IBM, where the primary host agent controls all action-based script invocations.

Instana traces and analyzes every request. Services and endpoints are automatically discovered, and relationships between services, endpoints, and your infrastructure are autocorrelated and stored in our Dynamic Graph.

Based on the data that is collected from tracers and sensors, KPIs are calculated for calls, latency, and erroneous calls. KPIs help you discover the health of every individual service and then the health of your entire infrastructure.

Services are a part of application monitoring and provide a logical view of your system. Services are derived from infrastructure entities such as hosts, containers, and processes. Incoming calls are correlated to infrastructure entities and enriched with infrastructure data; for example, the Kubernetes pod label or SpringBoot application name. After this infrastructure-linking processing step, a service mapping step maps the enriched calls to generate a service name per call based on a set of rules. Instana comes with an extensive set of predefined rules to generate the best possible service name for you automatically. To fine-tune the service mapping, you can create your own custom rules, see customize service mapping.

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.
