description

Build AIOps agents for Huawei Cloud that use CSS/OpenSearch as a Splunk replacement, integrate LTS/CTS/AOM/CES for monitoring and audit, employ LangGraph state machine orchestration with approval gates, LlamaIndex knowledge retrieval, Prometheus/Grafana metrics, and auto-remediation via FunctionGraph. Use when Codex must design, provision, or generate an AIOps Agent for automatic anomaly identification, alert governance, cross-service log correlation, runbook-driven remediation, action-level enforcement (L0 read-only, L1 suggest, L2 approve+execute, L3 forbidden), or CSS-based O&M analytics on Huawei Cloud.

AI-Agent-CSS-Ops-Skill

Overview

An intelligent O&M agent for Huawei Cloud that replaces Splunk with CSS (Cloud Search Service / OpenSearch), automates anomaly detection and remediation, and enforces safe action levels through a 4-tier policy engine.

Core stack: LangGraph (state machine) + LlamaIndex (knowledge) + CSS/OpenSearch (log analytics) + Huawei Cloud SDK (AOM, CES, CTS, FunctionGraph) + Prometheus/Grafana (metrics) + OpenTelemetry (tracing)

Key innovation: CSS + AI replaces Splunk's SIEM/SOAR capabilities at lower cost, with native Huawei Cloud integration. CSS serves as the unified data plane for logs, metrics, alerts, audit events, and incident records — replacing Splunk's Common Information Model with 5 purpose-built index templates.

Use This Skill When

• Customer says "we can't operate our cloud" or "alerts are noise"
• Need to replace Splunk with CSS on Huawei Cloud
• Building auto-remediation for CSS, ECS, CCE, GaussDB, VPN, CBR
• Implementing alert governance with approval gates
• Designing cross-service log correlation (LTS + CTS + CSS)
• Creating O&M runbooks with action-level enforcement
• Need a state-machine-driven incident response workflow

Architecture

LangGraph State Machine

8-state flow with conditional routing:

Alert → Observe → Diagnose → Recommend → Preview → Approve → Execute → Verify → Report

Conditional routing after Approve:

• L0/L1 actions: Skip execution, go directly to Report
• L2 + approved: Proceed to Execute
• L2 + rejected/expired: Go to Report (escalation)
• L2 + pending: Stay in Approve (polling for human decision)
• L3 actions: Blocked at Recommend, escalate to human

Conditional routing after Verify:

• healthy: Go to Report (incident resolved)
• degraded + loops < max: Go back to Observe (re-diagnose, max 2 loops)
• failed or max loops: Go to Report (escalation)

CSS-as-Splunk Pipeline

LTS (logs) ──→ CSS ops_logs-*
CTS (audit) ──→ CSS ops_cts-*
AOM/CES (metrics) ──→ CSS ops_metrics-*
                         ↓
              Anomaly Detection (LLM + statistical)
                         ↓
              Alert Governance (L0/L1/L2/L3)
                         ↓
              Remediation (FunctionGraph / SDK)
                         ↓
              Incident Report → CSS ops_incidents-*

5 CSS index templates define a common field schema (timestamp, source_service, resource_id, region, severity, correlation_id, trace_id) — replacing Splunk's Common Information Model.

Action Level Enforcement

Level	Scope	Approval	Example Tools
L0	Read-only	Auto	aom.list_alarms, ces.show_metric_data, cts.list_traces, css.get_cluster_info
L1	Suggest	Auto	runbook.lookup, runbook.render, diagnosis.recommend
L2	Execute	HMAC token (15-min TTL)	css.scale_out, ecs.resize, cce.restart_pod, functiongraph.invoke
L3	Destructive	Blocked	ecs.delete_server, css.delete_cluster, vpc.delete_vpc, iam.delete_user

Core Components

1. LangGraph State Machine — agent/ops_agent_state.py

Class: OpsAgent

State (OpsAgentState TypedDict, 22 fields):

Phase	Fields
Input	alert_event, alert_source, alert_severity
Observation	observed_metrics, observed_logs, observed_cts_events, observation_summary
Diagnosis	root_cause, related_incidents, confidence_score
Recommendation	recommended_action, runbook_id, runbook_steps, action_level
Preview	preview_result, preview_summary
Approval	approval_token, approval_status, approver_identity
Execution	execution_result, execution_timestamp
Verification	verification_metrics, verification_status
Report	incident_report, report_url
Meta	trace_id, agent_version, loop_count

Node implementations:

• observe_node — Collect metrics (AOM/CES), logs (CSS), CTS events; LLM summarizes observations
• diagnose_node — LLM identifies root cause; knowledge base searches past incidents
• recommend_node — Match runbook by alert type; determine action level from highest step level
• preview_node — Dry-run each step via tools.dry_run(); show effects without execution
• approve_node — L0/L1 auto-approve; L2 generate HMAC token; L3 block; demo mode auto-approves L2
• execute_node — Run L2 steps via remediation_executor; skip L0/L1; block L3
• verify_node — Check health via monitor.assess_health(); return healthy/degraded/critical
• report_node — Build incident report; persist to CSS ops_incidents-* index

Graph compilation: InMemorySaver checkpointer for state persistence across execution.

2. Action Policy Engine — agent/action_policy.py

Class: ActionPolicy

Loads action_levels.json (45 tools) and forbidden_actions.json (8 L3 tools) at init.

Key methods:

• classify(tool_name) → L0/L1/L2/L3 (unknown defaults to L3)
• enforce(tool_name, approval_token) → {allowed, level, reason, requires_approval}
• is_forbidden(tool_name) → bool
• is_allowed(tool_name, max_level) → bool
• get_tools_by_level(level) → list of tool names

Policy distribution: 23 L0 tools, 5 L1 tools, 9 L2 tools, 8 L3 tools.

3. Approval Token — agent/approval_token.py

Class: ApprovalToken

HMAC-SHA256 token: HMAC-SHA256("{tool_name}:{params_hash}:{timestamp}:{approver}", HWC_SECRET_ACCESS_KEY)

Key methods:

• generate(tool_name, params, requested_by) → {token, expires_at, action, params_hash}
• approve(token, approver_identity) → validates and marks approved
• reject(token, approver_identity) → marks rejected
• validate(token, tool_name, params) → {valid, status, reason}
• get_status(token) → pending/approved/rejected/expired

TTL: 900 seconds (15 minutes), configurable via APPROVAL_TTL_SECONDS.

4. AOM/CES Connector — agent/aom_ces_connector.py

Class: AOMCESConnector

Unified monitoring connector with TTL cache (60s for metrics, 300s for alarms).

Key methods:

• get_current_metrics(resource_type, resource_id, metric_names) → metric dict
• get_alarm_state(alarm_id) → alarm status
• assess_health(resource_type, resource_id) → {status, metrics, thresholds} where status ∈ {healthy, degraded, critical}
• get_metric_history(metric_name, resource_id, period) → time series

Demo mode: returns synthetic metrics when DEMO_MODE=true.

5. CTS Connector — agent/cts_connector.py

Class: CTSConnector

Key methods:

• get_recent_events(resource_id, resource_type, minutes) → list of CTS trace records
• find_config_changes(resource_id, since) → filtered for update/create/delete events
• correlate_with_alert(alert) → CTS events near alert timestamp (change-caused-anomaly detection)

6. CSS Log Correlator — agent/css_log_correlator.py

Class: CSSLogCorrelator

Cross-service correlation across ops_logs-*, ops_alerts-*, ops_cts-* indices.

Key methods:

• query_recent_logs(resource_id, service, severity, minutes) → log records
• correlate_events(alert, correlation_fields, time_window_minutes) → related events across all indices
• search_incident_history(root_cause_keywords, limit) → similar past incidents
• index_incident(incident) → persist to ops_incidents-*, returns doc ID
• bulk_ingest(index_name, documents) → bulk index, returns success count

Demo mode: all methods return empty results when CSS is unreachable. URL parsing uses urllib.parse.urlparse for robust host/port extraction.

7. Huawei Cloud SDK Tool Registry — agent/tools_huawei_cloud.py

Class: HuaweiCloudToolRegistry

SDK builder pattern: BasicCredentials + HttpConfig + Region (reuses css-testing/huawei_css_api.py).

SDK connectors:

• AOMTools: list_alarms, show_alarm_history, list_components, show_component_metrics
• CESTools: list_metrics, show_metric_data, list_alarms, show_alarm_history
• CTSTools: list_traces, list_trace_quotas
• CSSTools: cluster info, node operations (reuses css-testing)
• ECSTools: server operations (reuses enterprise-rag-agent)
• CCETools: list_pods, show_pod, restart_pod, scale_deployment
• FunctionGraphTools: invoke_function
• VPNTools, CBRTools

Key methods:

• dry_run(tool_name, params) → preview without execution
• execute(tool_name, params) → live execution

8. Knowledge Base — agent/tools_knowledge.py

Class: OpsKnowledgeBase

LlamaIndex + CSS/OpenSearch vector store for runbook and incident retrieval.

Graceful fallback: When llama_index is not installed, falls back to direct CSS multi_match query. All methods return empty results instead of raising ImportError.

Key methods:

• search_runbooks(alert_type, root_cause) → matching runbook chunks
• search_past_incidents(description, limit) → similar incident records
• index_runbook(runbook_path) → index a runbook document
• index_incident_record(incident) → index a completed incident

9. Runbook Engine — agent/runbook_engine.py

Class: RunbookEngine

Key methods:

• lookup_runbook(alert_type) → matching runbook filename (e.g., css_cluster_high_cpu → runbook_css_high_cpu.md)
• render_runbook(runbook_id, context) → list of steps with {{variable}} substitution
• preview_runbook(runbook_id, context) → human-readable summary without execution

Step parsing: each ## Step N heading becomes a step dict with step_num, title, tool, level, params.

10. Remediation Executor — agent/remediation_executor.py

Class: RemediationExecutor

• Direct SDK calls for simple actions (CSS scale-out, ECS reboot)
• FunctionGraph invocation for complex remediation functions
• Records execution result and duration

11. MaaS Client — agent/maas_client.py

OpenAI-compatible client pointed at Huawei Cloud MaaS endpoint.

Functions:

• call_maas(client, system_prompt, user_prompt, model, temperature, max_tokens) → text response
• call_maas_with_thinking(client, ...) → {thinking, text} with reasoning budget

12. OpenTelemetry — agent/otel_tracing.py

Functions:

• init_otel_tracing(endpoint, service_name) — Initialize OTel with safe defaults
• get_tracer(name) — Get a named tracer instance

13. Prometheus Tools — agent/tools_prometheus.py

Class: PrometheusTools

• query_promql(query) — Execute PromQL query
• query_range(query, start, end, step) — Range query
• get_grafana_dashboard(dashboard_id) — Fetch dashboard JSON

resource_id	keyword	Resource identifier
region	keyword	Huawei Cloud region
severity	keyword	Event severity (critical/high/medium/low)

Template-Specific Fields

ops_logs_template.json — Log records from LTS

• log_level, message (text), source_host, application

ops_metrics_template.json — Metric data from AOM/CES

• metric_name, namespace, value (double), unit, dimensions (nested)

ops_alerts_template.json — Alert events from AOM

• alert_id, alert_type, alert_source, resource_type, metric_value (double), threshold (double), description (text)

ops_cts_template.json — CTS audit trail events

• incident_id, root_cause (text), confidence_score (double), action_level, approval_status, verification_status, execution_result (nested), recommended_action (text)

---

Runbook Design

Each runbook follows this structure:

# Runbook: [Scenario Name]

## Metadata
- alert_type: [matches alert_type field]
- action_level: [L1 or L2]

## Step 1: [Title]
  Tool: `[tool.name]`
  Level: [L0/L1/L2]
  Params: `{"key": "{{variable}}"}`

## Step 2: [Title]
  ...

Variable substitution: {{alert_type}}, {{resource_id}}, {{resource_type}}, {{region}}, {{metric_value}}, {{threshold}}, {{root_cause}} are replaced with context values at render time.

Action level determination: The highest level across all steps becomes the runbook's action level. If any step is L3, the entire runbook is blocked.

Troubleshooting

ModuleNotFoundError: llama_index

LlamaIndex has a heavy dependency chain. tools_knowledge.py includes a graceful fallback — when llama_index is not installed, it uses direct CSS multi_match queries instead. Set HAS_LLAMAINDEX = False automatically on import failure.

ModuleNotFoundError: openai

Install: pip install openai. Required for MaaS LLM inference.

TypeError: Invalid checkpointer provided

LangGraph 1.1+ changed the SqliteSaver API. The agent uses InMemorySaver() instead. If you need persistent checkpoints across restarts, use:

from langgraph.checkpoint.sqlite.aio import AsyncSqliteSaver
# or
from langgraph.checkpoint.memory import InMemorySaver

CSS endpoint unreachable from WSL

The CSS endpoint (192.168.0.23:9200) is internal to the ECS VPC. Solutions:

1. Deploy the agent on ECS (recommended — uses systemd service)
2. SSH tunnel: ssh -L 9200:192.168.0.23:9200 root@101.44.184.244
3. Set DEMO_MODE=true to skip CSS connections

CSS _count returning 0 after bulk write

OpenSearch indices need a refresh before querying. Add refresh=True to the index call, or manually:

curl -X POST "http://CSS:9200/index/_refresh"

openai.OpenAIError: Missing credentials

The .env file must be loaded before creating the MaaS client. ops_agent_config.py auto-loads .env via python-dotenv. If running standalone, ensure HUAWEI_MAAS_API_KEY is set in the environment.

Approval token approver keyword error

The ApprovalToken.approve() method signature is approve(token, approver_identity), not approve(token, approver=...). Use the positional parameter name approver_identity.

Business KPI

• MTTR reduction: Automated diagnosis + runbook execution vs. manual expert triage
• Ticket diagnosis time reduction: LLM root cause analysis in seconds vs. hours
• Alert noise reduction: Action level governance filters L0/L1 from human review
• Compliance: CTS audit trail + approval tokens provide full accountability
• Cost savings: CSS replaces Splunk at lower cost with native Huawei Cloud integration
• Customer outcome: Shift from "can't use cloud" to "AI helps me use cloud"
