Azure Monitor OpenTelemetry SDK for TypeScript

Overview

This public intake copy packages

plugins/antigravity-awesome-skills-claude/skills/azure-monitor-opentelemetry-ts

https://github.com/sickn33/antigravity-awesome-skills

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses

metadata.json

ORIGIN.md

Azure Monitor OpenTelemetry SDK for TypeScript Auto-instrument Node.js applications with distributed tracing, metrics, and logs.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Environment Variables, Quick Start (Auto-Instrumentation), ESM Support (Node.js 18.19+), Full Configuration, Custom Traces, Custom Metrics.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: Auto-instrument Node.js applications with distributed tracing, metrics, and logs.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. bash # Distro (recommended - auto-instrumentation) npm install @azure/monitor-opentelemetry # Low-level exporters (custom OpenTelemetry setup) npm install @azure/monitor-opentelemetry-exporter # Custom logs ingestion npm install @azure/monitor-ingestion ### Trace Exporter typescript import { AzureMonitorTraceExporter } from "@azure/monitor-opentelemetry-exporter"; import { NodeTracerProvider, BatchSpanProcessor } from "@opentelemetry/sdk-trace-node"; const exporter = new AzureMonitorTraceExporter({ connectionString: process.env.APPLICATIONINSIGHTSCONNECTIONSTRING }); const provider = new NodeTracerProvider({ spanProcessors: [new BatchSpanProcessor(exporter)] }); provider.register(); ### Metric Exporter typescript import { AzureMonitorMetricExporter } from "@azure/monitor-opentelemetry-exporter"; import { PeriodicExportingMetricReader, MeterProvider } from "@opentelemetry/sdk-metrics"; import { metrics } from "@opentelemetry/api"; const exporter = new AzureMonitorMetricExporter({ connectionString: process.env.APPLICATIONINSIGHTSCONNECTIONSTRING }); const meterProvider = new MeterProvider({ readers: [new PeriodicExportingMetricReader({ exporter })] }); metrics.setGlobalMeterProvider(meterProvider); ### Log Exporter typescript import { AzureMonitorLogExporter } from "@azure/monitor-opentelemetry-exporter"; import { BatchLogRecordProcessor, LoggerProvider } from "@opentelemetry/sdk-logs"; import { logs } from "@opentelemetry/api-logs"; const exporter = new AzureMonitorLogExporter({ connectionString: process.env.APPLICATIONINSIGHTSCONNECTIONSTRING }); const loggerProvider = new LoggerProvider(); loggerProvider.addLogRecordProcessor(new BatchLogRecordProcessor(exporter)); logs.setGlobalLoggerProvider(loggerProvider); typescript import { SpanProcessor, ReadableSpan } from "@opentelemetry/sdk-trace-base"; import { Span, Context, SpanKind, TraceFlags } from "@opentelemetry/api"; import { useAzureMonitor } from "@azure/monitor-opentelemetry"; class FilteringSpanProcessor implements SpanProcessor { forceFlush(): Promise<void> { return Promise.resolve(); } shutdown(): Promise<void> { return Promise.resolve(); } onStart(span: Span, context: Context): void {} onEnd(span: ReadableSpan): void { // Add custom attributes span.attributes["CustomDimension"] = "value"; // Filter out internal spans if (span.kind === SpanKind.INTERNAL) { span.spanContext().traceFlags = TraceFlags.NONE; } } } useAzureMonitor({ spanProcessors: [new FilteringSpanProcessor()] });
2. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
3. Read the overview and provenance files before loading any copied upstream support files.
4. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
5. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
6. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
7. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.

import { NodeTracerProvider, BatchSpanProcessor } from "@opentelemetry/sdk-trace-node";

const exporter = new AzureMonitorTraceExporter({
  connectionString: process.env.APPLICATIONINSIGHTS_CONNECTION_STRING

});

provider.register();

import { AzureMonitorMetricExporter } from "@azure/monitor-opentelemetry-exporter";
import { PeriodicExportingMetricReader, MeterProvider } from "@opentelemetry/sdk-metrics";
import { metrics } from "@opentelemetry/api";

const exporter = new AzureMonitorMetricExporter({
  connectionString: process.env.APPLICATIONINSIGHTS_CONNECTION_STRING
});

const meterProvider = new MeterProvider({
  readers: [new PeriodicExportingMetricReader({ exporter })]
});

metrics.setGlobalMeterProvider(meterProvider);

Log Exporter

import { AzureMonitorLogExporter } from "@azure/monitor-opentelemetry-exporter";
import { BatchLogRecordProcessor, LoggerProvider } from "@opentelemetry/sdk-logs";
import { logs } from "@opentelemetry/api-logs";

const exporter = new AzureMonitorLogExporter({
  connectionString: process.env.APPLICATIONINSIGHTS_CONNECTION_STRING
});

const loggerProvider = new LoggerProvider();
loggerProvider.addLogRecordProcessor(new BatchLogRecordProcessor(exporter));

logs.setGlobalLoggerProvider(loggerProvider);

Imported: Custom Span Processor

import { SpanProcessor, ReadableSpan } from "@opentelemetry/sdk-trace-base";
import { Span, Context, SpanKind, TraceFlags } from "@opentelemetry/api";
import { useAzureMonitor } from "@azure/monitor-opentelemetry";

class FilteringSpanProcessor implements SpanProcessor {
  forceFlush(): Promise<void> { return Promise.resolve(); }
  shutdown(): Promise<void> { return Promise.resolve(); }
  onStart(span: Span, context: Context): void {}
  
  onEnd(span: ReadableSpan): void {
    // Add custom attributes
    span.attributes["CustomDimension"] = "value";
    
    // Filter out internal spans
    if (span.kind === SpanKind.INTERNAL) {
      span.spanContext().traceFlags = TraceFlags.NONE;
    }
  }
}

useAzureMonitor({
  spanProcessors: [new FilteringSpanProcessor()]
});

Examples

Example 1: Ask for the upstream workflow directly

Use @azure-monitor-opentelemetry-ts to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @azure-monitor-opentelemetry-ts against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @azure-monitor-opentelemetry-ts for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @azure-monitor-opentelemetry-ts using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Call useAzureMonitor() first - Before importing other modules
• Use ESM loader for ESM projects - --import @azure/monitor-opentelemetry/loader
• Enable offline storage - For reliable telemetry in disconnected scenarios
• Set sampling ratio - For high-traffic applications
• Add custom dimensions - Use span processors for enrichment
• Graceful shutdown - Call shutdownAzureMonitor() to flush telemetry
• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in

plugins/antigravity-awesome-skills-claude/skills/azure-monitor-opentelemetry-ts

metadata.json

ORIGIN.md

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated

SKILL.md

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
