/ai-observability Skill

Analyze AI model inference performance, GPU utilization, OpenShift cluster health, and distributed traces on Red Hat OpenShift AI. This is a query-driven, read-only skill: the user asks a question, and the skill routes to the appropriate observability domain (vLLM metrics, OpenShift health, Tempo traces, or cross-domain correlation via Korrel8r).

Prerequisites

• list_inference_services - List deployed models with structured status for context
• get_inference_service - Get InferenceService status for context

If rhoai is unavailable or returns errors: Use openshift tools as fallback — resources_list with apiVersion: serving.kserve.io/v1beta1, kind: InferenceService replaces list_inference_services; resources_list with apiVersion: v1, kind: Namespace, labelSelector: opendatahub.io/dashboard=true replaces list_data_science_projects.

Optional MCP Server: openshift (OpenShift MCP Server)

Optional MCP Tools (from openshift):

• resources_get (from openshift) - Get raw resource details for context
• resources_list (from openshift) - List InferenceServices, Namespaces (fallback for rhoai tools)
• pods_list (from openshift) - List predictor pods for correlation context

Common prerequisites (KUBECONFIG, OpenShift+RHOAI cluster, verification protocol): See skill-conventions.md.

Additional environment variables:

• AI_OBSERVABILITY_MCP_URL - URL for the AI Observability MCP server (e.g., http://aiobs-mcp.apps.cluster.example.com)

Additional cluster requirements:

• AI Observability MCP server deployed on-cluster (from quay.io/ecosystem-appeng/aiobs-mcp-server)
• Prometheus configured with vLLM and OpenShift metrics
• Tempo configured for distributed tracing (optional, for trace analysis)
• Korrel8r deployed (optional, for cross-domain correlation)

When to Use This Skill

Use this skill when you need to:

• Check model inference performance (latency, throughput, error rates)
• View GPU inventory and utilization across the cluster
• Analyze OpenShift cluster health metrics by category
• Trace slow inference requests with distributed tracing (Tempo)
• Correlate signals across logs, metrics, traces, and alerts (Korrel8r)
• Run custom PromQL queries against cluster Prometheus

Do NOT use this skill when:

• You need to troubleshoot a failed deployment (use /debug-inference)
• You want to deploy or redeploy a model (use /model-deploy)
• You need to create or modify a ServingRuntime (use /serving-runtime-config)

Workflow

Step 1: Verify MCP and Triage Intent

Verify ai-observability MCP server is reachable. If any tool call fails with a connection error:

Cannot execute /ai-observability: ai-observability MCP server is not reachable.

Setup Instructions:
1. Deploy the server on your cluster from quay.io/ecosystem-appeng/aiobs-mcp-server
   See: https://github.com/rh-ai-quickstart/ai-observability-summarizer
2. Set AI_OBSERVABILITY_MCP_URL to the server route URL
3. Restart Claude Code to reload MCP servers

Options: setup (show deployment guide) / abort

WAIT for user decision if MCP is unavailable.

Classify user query into one of these domains:

Domain	Trigger Phrases	Primary Tool(s)
Model Discovery	"what models", "list models", "what's deployed"	list_models, list_vllm_namespaces
GPU Inventory	"GPU", "GPU utilization", "what GPUs", "available hardware"	get_gpu_info
vLLM Performance	"latency", "throughput", "performance", "how is [model]", "slow"	analyze_vllm
OpenShift Health	"cluster health", "namespace metrics", "node health", "pods"	analyze_openshift
Tracing	"trace", "latency trace", "slow request", "spans"	query_tempo_tool
Correlation	"correlate", "root cause", "what's related to"	korrel8r_get_correlated
Custom PromQL	"PromQL", "custom query", "specific metric"	execute_promql

If the intent is ambiguous, present the domain options and ask the user to choose.

If the user specifies a model name, use list_models first to verify it exists and get the correct identifier. If the user does not specify a namespace, use list_vllm_namespaces or list_openshift_namespaces to discover available namespaces and present them.

Project context (if rhoai MCP available): For "what's running" or "what's deployed" queries, use list_data_science_projects (from rhoai) to provide project-level overview. Use list_inference_services (from rhoai) per project to show deployed models with status.

WAIT for user to confirm scope before proceeding to analysis.

• /model-deploy to redeploy with different configuration
• Custom PromQL queries for ongoing monitoring

If everything looks healthy, confirm: "All monitored metrics are within normal ranges."

Common Issues

Issue 1: AI Observability MCP Server Not Deployed

Error: Connection refused or timeout when reaching AI_OBSERVABILITY_MCP_URL

Cause: The AI Observability MCP server is not deployed on the cluster, or the route/service is not accessible.

Solution:

1. Deploy the server from quay.io/ecosystem-appeng/aiobs-mcp-server -- see https://github.com/rh-ai-quickstart/ai-observability-summarizer
2. Verify the route is accessible: oc get route -n [namespace] aiobs-mcp
3. Set AI_OBSERVABILITY_MCP_URL to the route URL
4. Restart Claude Code to reload MCP servers

Issue 2: No Models Found in Monitoring

Error: list_models returns empty results

Cause: vLLM metrics are not being scraped by Prometheus, or no InferenceServices are deployed.

Solution:

1. Verify InferenceServices exist: use resources_list from openshift MCP
2. Check that Prometheus ServiceMonitor is configured for vLLM metrics
3. Verify the vLLM serving container exposes /metrics endpoint

Issue 3: Tempo Traces Not Available

Error: query_tempo_tool returns empty or connection error

Cause: Tempo is not deployed, or distributed tracing is not configured for the inference stack.

Solution:

1. Verify Tempo is deployed in the cluster
2. Check OpenTelemetry instrumentation on the inference endpoints
3. Verify Tempo datasource is configured in the MCP server

Issue 4: Korrel8r Correlation Returns No Results

Error: korrel8r_get_correlated returns empty correlation

Cause: Korrel8r is not deployed, or the query format is incorrect.

Solution:

1. Verify Korrel8r is deployed and accessible
2. Check the query format matches Korrel8r domain syntax (e.g., k8s:Pod:{"namespace":"[ns]","name":"[pod]"})
3. Ensure the target pod/namespace exists and has generated observability signals

Critical: Human-in-the-Loop Requirements

See skill-conventions.md for general HITL and security conventions.

Skill-specific checkpoints:

• After triage (Step 1): confirm analysis scope (model, namespace, time range) before running queries
• After initial analysis (Step 2): present follow-up options, wait for user choice
• After correlation (Step 2f): confirm before drilling into correlated signals
• NEVER expose raw Prometheus/Tempo credentials or internal cluster endpoints in output
• NEVER execute unbounded PromQL queries (no time limit, extremely wide label selectors) without confirming with the user
