Huawei Cloud AgentArts OpenTelemetry Ingestion

Overview

This skill enables OpenTelemetry (OTel) telemetry data ingestion into Huawei Cloud AgentArts observability platform (agent-ops). It covers four functional areas:

1. OTel Telemetry Ingestion — Route trace/metrics/logs from applications to

agent-ops via APM deliverConfig forwarding (Path A, recommended) or OTLP direct connection (Path B, verification only).

1. AI Agent Observation — Instrument AI/LLM applications with OpenTelemetry GenAI

semantic conventions (gen_ai.* spans, token usage metrics, model call chains).

1. Auto-Configuration — Detect application language/framework and generate

ready-to-use OTel SDK/Collector configuration.

1. Ingestion Diagnostics — Verify data arrival via agent-ops observation APIs

(trace/session/metric/log queries).

Architecture

Application (OTel SDK/Collector)
  │
  ├── Path A (Recommended): OTLP → APM → deliverConfig → Kafka → agent-ops
  │
  └── Path B (Verification): OTLP → Collector → agent-ops (if OTLP receiver available)

Data Flow

See references/dataflow-diagram.md for the Mermaid diagram.

Prerequisites

1. Huawei Cloud Credentials

Set credentials out-of-band. Never paste AK/SK in chat.

export HUAWEI_ACCESS_KEY="<your-access-key-id>"
read -rs HUAWEI_SECRET_KEY; export HUAWEI_SECRET_KEY
export HUAWEI_REGION="cn-southwest-301"

Verify by running the CLI configure list command (if hcloud CLI is installed).

2. hcloud CLI (KooCLI)

Install: https://support.huaweicloud.com/qs-hcli/hcli02003.html

3. APM Subscription

Confirm agent-ops has subscribed to APM observation. If not subscribed, complete subscription first (management plane: SubscribeOpsObservation / OpenOpsObservation).

4. IAM Permissions

See references/iam-policies.md for least-privilege policy.

5. OTel SDK

Install language-specific OTel packages:

• Java: opentelemetry-javaagent (download JAR)
• Python: pip install opentelemetry-sdk opentelemetry-exporter-otlp-proto-http
• Node.js: npm install @opentelemetry/sdk-node @opentelemetry/exporter-trace-otlp-http
• Go: go get go.opentelemetry.io/otel go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp

Workflow

Step 1: Confirm Application Environment

Detect the application language/framework:

If existing OTel config is detected, read and adjust rather than overwrite.

Step 2: Confirm Target Environment

Step 3: Confirm Ingestion Scope

• Data types: traces / metrics / logs
• Application name (appName) and business ID (businessId)

Step 4: Execute Ingestion (Path A or B)

Path A: APM deliverConfig Ingestion (Recommended)

4a. Create tracing business (official API — verified via IAM authorization reference):

hcloud APM CreateBusiness --cli-region={region} \
  --name="otel-business-<appName>" \
  --display_name="<appName>" \
  --descp="otel business" \
  --cmdb_datasource_type="AGENTRUN"

API equivalent (official path):

POST {APM_ENDPOINT}/v1/apm2/openapi/tracing/business/create
Content-Type: application/json
X-Auth-Token: {iam_token}

{
  "name": "otel-business-<appName>",
  "display_name": "<appName>",
  "descp": "otel business",
  "cmdb_datasource_type": "AGENTRUN"
}

4b. Get business token (official API):

hcloud APM ShowToken --cli-region={region} \
  --business_id={business_id}

API equivalent:

GET {APM_ENDPOINT}/v1/apm2/openapi/tracing/business/token/{business_id}
X-Auth-Token: {iam_token}
x-business-id: {business_id}

Record the returned token for application-side OTel exporter auth.

4c. Get access point (official API):

POST {APM_ENDPOINT}/v1/apm2/openapi/tracing/access/get-access-point/{business_id}
X-Auth-Token: {iam_token}
x-business-id: {business_id}

4d. Create deliverConfig forwarding (user-provided API — requires manual verification):

Note: This endpoint is from user-provided reference, not found in official public docs. Verify the exact path in Huawei Cloud API Explorer before use.

POST {APM_INTERNAL_ENDPOINT}/v2/trace/deliver-config?region=cn-southwest-301
x-apply-domain-id: {domain_id}
x-apply-role-name: te_admin
Content-Type: application/json

{
  "config_name": "AgentArts-<appName>",
  "deliver_domain": "{domain_id}",
  "deliver_otel_trace": true,
  "descp": "otel trace deliver",
  "business_ids": "{business_id}",
  "application_ids": "{app_id}",
  "otel_trace_topic_name": "{kafka_topic}",
  "kafka_config": {
    "bootstrap.servers": "{bootstrap_servers}",
    "acks": "all",
    "retries": 1,
    "sasl.mechanism": "PLAIN",
    "security.protocol": "SASL_SSL",
    "username": "{kafka_user}",
    "password": "{kafka_password}"
  }
}

Modify: PUT /v2/trace/deliver-config (body: {id, deliver_otel_trace}) Delete: DELETE /v2/trace/deliver-config/{id}?region=

4e. Configure application-side OTel SDK/Collector

Java Agent:

java -javaagent:opentelemetry-javaagent.jar \
  -Dotel.service.name=<appName> \
  -Dotel.exporter.otlp.endpoint={APM_ENDPOINT} \
  -Dotel.exporter.otlp.headers="Authorization=Bearer {token}" \
  -jar app.jar

Python SDK:

from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.trace.export import BatchSpanProcessor

exporter = OTLPSpanExporter(
    endpoint=f"{APM_ENDPOINT}/v1/traces",
    headers={"Authorization": f"Bearer {token}"},
)

Node.js SDK:

const { NodeSDK } = require('@opentelemetry/sdk-node');
const { OTLPTraceExporter } = require('@opentelemetry/exporter-trace-otlp-http');

const traceExporter = new OTLPTraceExporter({
  url: `${APM_ENDPOINT}/v1/traces`,
  headers: { Authorization: `Bearer ${token}` },
});
const sdk = new NodeSDK({ traceExporter, serviceName: '<appName>' });
sdk.start();

Go SDK:

import (
  "go.opentelemetry.io/otel"
  "go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp"
  "go.opentelemetry.io/otel/sdk/resource"
  sdktrace "go.opentelemetry.io/otel/sdk/trace"
  semconv "go.opentelemetry.io/otel/semconv/v1.21.0"
)

exporter, _ := otlptracehttp.New(ctx,
  otlptracehttp.WithEndpoint(APM_ENDPOINT),
  otlptracehttp.WithHeaders(map[string]string{"Authorization": "Bearer " + token}),
)

OTel Collector (config.yaml):

exporters:
  otlp/apm:
    endpoint: "{APM_ENDPOINT}:443"
    headers:
      Authorization: "Bearer {token}"
service:
  pipelines:
    traces:
      exporters: [otlp/apm]
    metrics:
      exporters: [otlp/apm]
    logs:
      exporters: [otlp/apm]

Path B: OTLP Direct Connection (Verification Only)

As of current agent-ops version, the backend contains OTLP proto definitions but no OTLP receiver implementation. Path B is for verification testing only.

1. Deploy OTel Collector with OTLP receiver and test exporter.
2. Generate test spans from a sample application.
3. Verify data export to confirm SDK/Collector config correctness.
4. Use management plane APIs to verify data reachability.

Step 5: AI Agent Observation (GenAI Semantic Conventions)

Instrument AI/LLM applications with OpenTelemetry GenAI semantic conventions:

Python example (LLM tracing):

from opentelemetry import trace

tracer = trace.get_tracer("agentarts-ai")

with tracer.start_as_current_span("invoke_agent") as span:
    span.set_attribute("gen_ai.system", "huawei-cloud")
    span.set_attribute("gen_ai.request.model", "pangu-4.0")
    # ... agent logic ...
    span.set_attribute("gen_ai.usage.input_tokens", input_tokens)
    span.set_attribute("gen_ai.usage.output_tokens", output_tokens)

Node.js example:

const tracer = trace.getTracer('agentarts-ai');
const span = tracer.startSpan('invoke_agent');
span.setAttribute('gen_ai.system', 'huawei-cloud');
span.setAttribute('gen_ai.request.model', 'pangu-4.0');
// ... agent logic ...
span.setAttribute('gen_ai.usage.input_tokens', inputTokens);
span.setAttribute('gen_ai.usage.output_tokens', outputTokens);
span.end();

See references/genai-semconv.md for full attribute reference.

Step 6: Verify Data Arrival

Query agent-ops observation APIs to confirm data ingestion. These are management plane APIs — authenticate with IAM token (X-Auth-Token), not the OTel business-side Bearer token:

ShowOpsTrace (official — verified):

curl -X POST {AGENT_OPS_ENDPOINT}/v1/ops/observation/traces \
  -H "X-Auth-Token: {iam_token}" \
  -H "Content-Type: application/json" \
  -d '{"start_time": 1720000000000, "end_time": 1720600000000}'

ShowOpsAgentMetricTrend (official — verified):

curl -X POST {AGENT_OPS_ENDPOINT}/v1/ops/observation/metrics/trend \
  -H "X-Auth-Token: {iam_token}" \
  -H "Content-Type: application/json" \
  -d '{"start_time": 1720000000000, "end_time": 1720600000000}'

ListOpsSession (existence confirmed, path requires manual verification):

curl -X POST {AGENT_OPS_ENDPOINT}/v1/ops/observation/sessions \
  -H "X-Auth-Token: {iam_token}" \
  -H "Content-Type: application/json" \
  -d '{"start_time": 1720000000000, "end_time": 1720600000000}'

Note: Exact paths for ListOpsTrace, ListOpsSession, ShowOpsAgentMetricGauge, ListOpsAgentLog require manual verification in Huawei Cloud API Explorer. See references/verification-method.md.

Step 7: Ingestion Diagnostics

Common diagnostic checks:

Core Commands

Parameter Confirmation

KooCLI Command Format Standard

hcloud <Service> <Operation> --cli-region=<region> [--key=value ...]

Note: AgentArts observation APIs (ShowOpsTrace, ShowOpsAgentMetricTrend, etc.) are not yet confirmed in KooCLI. Use API (curl) mode for these operations.

• references/genai-semconv.md — OpenTelemetry GenAI semantic conventions

Edge Cases

Notes

• API verification status: APM tracing APIs are officially verified. AgentArts

observation APIs (ShowOpsTrace, ShowOpsAgentMetricTrend) are officially documented. DeliverConfig and some observation query APIs require manual verification.

• Credential security: Never hardcode AK/SK. Read from env vars or CLI profile.
• GenAI semconv: OpenTelemetry GenAI semantic conventions are in Development

status (as of OTel v1.41). Attribute names may change.

• Least privilege: See references/iam-policies.md for required permissions.
