Huawei Cloud Cce Daily Cluster Inspector

CCE Daily Cluster Inspector

Overview

This skill performs periodic, low-risk CCE cluster health inspections. It follows a quick-check-first strategy: run lightweight checks first, and only escalate to deep diagnosis when anomalies are detected. This avoids running heavy diagnostic actions on every inspection cycle.

This skill is strictly read-only — it never performs mutation actions. When risks are found, it outputs recommendations and hands off to the appropriate remediation skill.

Architecture: python3 scripts/huawei-cloud.py dispatcher → Huawei Cloud Python SDK + Kubernetes client → cluster status, Events, metrics, AOM alarms

Related Skills:

• huawei-cloud-cce-auto-remediation-runner — execute confirmed remediation actions (scale, drain, rollback, etc.)
• huawei-cloud-cce-root-cause-analyzer — cross-domain root cause analysis
• huawei-cloud-cce-pod-failure-diagnoser — deep Pod failure diagnosis
• huawei-cloud-cce-node-failure-diagnoser — deep Node failure diagnosis
• huawei-cloud-cce-network-failure-diagnoser — network connectivity, DNS, ELB diagnosis
• huawei-cloud-cce-alarm-correlation-engine — alarm correlation and deduplication
• huawei-cloud-cce-ops-report-generator — formal operations report generation

When to Use

• Daily or periodic cluster health check
• Quick heartbeat summary for operational dashboards
• Continuous operations report generation
• Post-change validation (read-only verification after changes made by other skills)
• First-pass triage before escalating to deep diagnosis

Do NOT use for:

• Executing remediation actions → use huawei-cloud-cce-auto-remediation-runner
• Deep single-resource diagnosis → use domain-specific diagnoser skills
• Capacity forecasting → use huawei-cloud-cce-capacity-trend-forecaster

Prerequisites

1. Python Dependencies

• Python 3.8+ with huaweicloudsdkcce, huaweicloudsdkcore, kubernetes packages
• Run environment check before first use

2. Credential Configuration

• Valid Huawei Cloud credentials (AK/SK mode)
• Security Rules:
  • Never expose AK/SK values in code, conversation, or commands
  • Never use echo to check credential values
  • Use environment variables: HUAWEI_AK, HUAWEI_SK, HUAWEI_REGION
  • Prefer IAM users over root account for cloud operations

export HUAWEI_AK=
export HUAWEI_SK=
export HUAWEI_REGION=cn-north-4

3. IAM Permission Requirements

Workflow

digraph inspection_flow {
    rankdir=TB;
    start [shape=doublecircle label="Start Inspection"];
    quick [shape=box label="Quick Check\nhuawei_cce_quick_check or\nhuawei_cce_auto_inspection"];
    healthy [shape=box label="Output Heartbeat\nSummary"];
    anomaly [shape=diamond label="Anomalies\nFound?"];
    deep [shape=box label="Deep Diagnosis\nor Parallel Inspection"];
    classify [shape=box label="Classify by:\nPod/Node/Event/\nAOM/ELB/Resource"];
    report [shape=box label="Generate Report\n(P0/P1/P2 risks)"];
    handoff [shape=box label="Recommend\nRemediation Handoff"];

    start -> quick;
    quick -> anomaly;
    anomaly -> healthy [label="No"];
    anomaly -> deep [label="Yes"];
    deep -> classify;
    classify -> report;
    report -> handoff;
}

Step-by-step:

1. Collect region, cluster_id, inspection scope, and report expectations from user
2. Run quick check first (huawei_cce_quick_check or huawei_cce_auto_inspection)
3. If healthy → output brief heartbeat summary
4. If anomalies found → run deep diagnosis or parallel inspection, grouped by Pod, Node, Event, AOM, ELB, Resource
5. Classify risks as P0/P1/P2 with recommended owner
6. Output read-only report; for actionable items, provide handoff checklist to huawei-cloud-cce-auto-remediation-runner
7. If formal report needed → call huawei_export_inspection_report

Core Tools

All actions dispatched through scripts/huawei-cloud.py using skill action=exec.

Quick Check (First Pass)

Deep Diagnosis (Escalation)

Aggregation & Reporting

Parameter Reference

Output Format

See references/output-schema.md for the complete JSON response structure.

Key output fields:

• summary — daily inspection summary text
• status — HEALTHY, WARNING, or CRITICAL
• cluster.region / cluster.cluster_id — cluster identification
• checks — list of check results
• risks — classified risk items (P0/P1/P2)
• recommended_followups — handoff recommendations to other skills
• report_file — optional exported report path

Risk Constraints

This skill operates under R1 read-only constraints:

• Only read-only actions allowed — no scaling, deletion, drain, reboot, hibernate, or awake
• Inspection reports must never contain AK/SK, tokens, certificates, or full kubeconfig
• Anomalies only produce recommendations; remediation must be confirmed via huawei-cloud-cce-auto-remediation-runner
• See references/risk-rules.md for full risk boundary details

Verification

1. Run environment check script
2. Call huawei_cce_cluster_auto_inspection with a test cluster
3. Verify the report contains all expected sections
4. Confirm read-only behavior (no mutation actions)

Best Practices

1. Quick check first — always start with huawei_cce_quick_check or huawei_cce_auto_inspection; avoid heavy checks on every cycle
2. Classify risks — label each anomaly as P0 (critical), P1 (warning), or P2 (low) with recommended owner
3. Hand off remediation — never attempt mutation actions; provide actionable checklist for huawei-cloud-cce-auto-remediation-runner
4. Scope appropriately — provide namespace to reduce noise when targeting specific workloads
5. Aggregate parallel results — when using huawei_cce_cluster_inspection_parallel, always call huawei_aggregate_inspection_results to consolidate
6. Use formal reports for operations reviews — call huawei_export_inspection_report when a persistent report is needed

Common Pitfalls

Reference Documents

Notes

1. This skill is read-only — it inspects and reports, never mutates cluster state
2. AK/SK must never be hardcoded — use environment variables only
3. All actions dispatched through scripts/huawei-cloud.py via skill action=exec; do not run scripts directly in shell
4. When risks require action, hand off to huawei-cloud-cce-auto-remediation-runner with a confirmation checklist
5. For deep single-resource diagnosis, delegate to domain-specific diagnoser skills (huawei-cloud-cce-pod-failure-diagnoser, huawei-cloud-cce-node-failure-diagnoser, etc.)
