# Fault Isolation Service

*/Services/Fault_Isolation_Service*

## Service Contract

**Sla**: Fault isolated and documented diagnosis delivered within a contracted time-to-isolate threshold based on incident severity.
**Input**:
- System alerts
- Event logs
- Network topology maps
**Output**:
- Fault localization report
- Root cause diagnosis
- Remediation recommendation
**Sla Basis**: turnaround-time
**Definition**: A service offering that analyzes system alerts, telemetry, and logs to pinpoint the exact location and underlying cause of a technical failure within an IT or network environment.
**Solves Problem**: [Unidentified System Failures](/Problems/Unidentified_System_Failures)
**Absorbs Process**: [Fault Management](/Processes/Fault_Management)
**Delivery Lenses**:
- human
- services-as-software
**Outcome Contract**: The provider identifies the exact failing component or root cause of the reported anomaly and delivers a definitive diagnosis with actionable remediation steps.

## Service Function Cascade

**Ai Role**: AI serves as the primary investigative engine, autonomously ingesting logs, correlating alerts, and using agentic loops to isolate faults, while a human engineer provides final approval on the diagnosis and remediation plan.
**Cascade**:
- Kind: Code · Note: Fetches system alerts, event logs, and topology maps via API. · Step: Ingest System Data · Verb: ingest · Realizes: Acquire System Telemetry · Oversight: none
- Kind: Code · Note: Groups related alerts and maps them against the network topology. · Step: Map Alert Topology · Verb: correlate · Realizes: Correlate Event Logs · Oversight: none
- Kind: Agentic · Note: Iteratively queries logs to trace the failure to its source component. · Step: Pinpoint Fault Origin · Verb: isolate · Realizes: Diagnose System Faults · Oversight: none
- Kind: Generative · Note: Generates the localization report, root cause diagnosis, and exact remediation steps. · Step: Formulate Remediation Plan · Verb: draft · Realizes: Draft Incident Report · Oversight: none
- Kind: Human · Note: A senior reliability engineer validates the root cause and remediation steps. · Step: Validate Diagnosis · Verb: validate · Realizes: Approve Remediation Plan · Oversight: approves

## Service Representative Offer

**Warranty**: The provider guarantees delivery of the isolated diagnosis within the severity-defined time-to-isolate threshold, issuing service credits for any incident that breaches the turnaround time.
**Price Band**: Roughly $50 to $250 per isolated incident, depending on infrastructure complexity and the required severity-level SLA.
**Pricing Kind**: UsageMeter
**Deliverables**:
- Fault localization report
- Root cause diagnosis
- Remediation recommendation playbook
**Delivery Mode**: The buyer provisions the service by integrating their monitoring tools and telemetry endpoints via API, enabling the provider to automatically ingest event logs and deliver diagnostic reports upon alert generation.
**Business Function**: ProvideService
**Agent Checkout Support**:
