The IBM Instana Observability documentation clearly defines several operating modes for the host agent, with INFRASTRUCTURE mode dedicated exclusively to monitoring system-level performance data. The verified extract states: "INFRASTRUCTURE mode configures the host agent to monitor the underlying host metrics and activate sensors for the technologies running on that host without tracing application-level transactions." It collects CPU, memory, disk, network metrics, and technology integrations like Docker or OS sensors while ignoring application instrumentation. This mode reduces overhead in environments that demand system observability without full APM tracing. APM mode, conversely, extends to application traces and requests. Cloud-specific modes such as AWS or ARM designate external monitoring integrations rather than agent behavior. INFRASTRUCTURE mode thus provides base telemetry visibility as per documented design and was verified in both formulations of the Instana agent guides (v1.0.277, v1.0.307).

OTLP (OpenTelemetry Protocol) enables modern, standards-based telemetry with Instana for traces and metrics. The official IBM Instana documentation explains that enabling OTLP support should be done during installation or upgrade viaHelm, using either values set in a YAML file or via the --set command line argument. This method is described as, "To enable OTLP, use Helm with the provided chart and set OTLP values in your values.yaml or with the --set flag." Helm automation allows administrators to easily manage, update, and version-control agent and collector configuration at scale—especially in Kubernetes environments. It is favored because it is compatible with Instana’s operator and dynamic config approaches. Manual edits in settings.hcl or params.yaml are not recommended or officially documented for enabling OTLP streams. Multiple tracers relate to instrumentation and are not for enabling the protocol itself. Using Helm provides a streamlined, repeatable and supported approach – per IBM Instana deployment best practices.

IBM Instana documents the merge logic of custom payloads for alerts and global configurations very clearly. The rule states: "If the same key is defined in both a global custom payload and an alert-specific payload, the value from the alert-specific payload will override the global value for that key." This ensures alert context management is precise, enabling targeted incident response with the most relevant and high-priority data. There is no concatenation, and no alert cancellation or error is triggered as Instana resolves key collisions silently by giving precedence to the more granular, context-specific setting (alert-level). This verified behavior guarantees custom alert events always contain relevant payloads, supporting accurate automated remediation or escalation.
