Systemtilstand

Systemtilstand is the current condition of a computer system, encompassing hardware, software, and network components, and indicating the system’s ability to perform its intended tasks. The concept is central to IT operations, monitoring, and service management, providing a snapshot of health and readiness.

Key aspects include hardware health (temperature, power status, CPU load, memory usage, disk capacity), software state (running services, application versions, configuration integrity), and network connectivity (reachability, latency, error rates). Together these elements determine whether the system can operate as expected.

Systemtilstand is typically observed and reported by monitoring and observability tools that collect metrics, events, and health checks. Representations include dashboards and health endpoints, using status categories such as OK, WARN, CRITICAL, or DOWN, often with timestamps and optional numeric scores or trends.

State models describe transitions between statuses, such as from UP to MAINTENANCE, or from OK to WARN to CRITICAL in response to thresholds or events, and to DOWN on failure. Systems may support automatic remediation or escalation based on tilstand, enabling faster responses and reduced downtime.

Applications include incident management, capacity planning, SLA reporting, and reliability engineering by providing a basis for prioritizing issues, forecasting resource needs, and validating recoveries after incidents. A clear articulation of systemtilstand helps operators coordinate responses and assess overall service health.

Scope can be granular, covering individual components or the entire system, and aggregation rules determine how component tilstands combine into an overall systemtilstand. Different layers—hardware, OS, applications—may each expose their own tilstand, which are then composed for an integrated view.
