## What it does

The skill hands your agent ready-made configs and code for instrumenting apps with OpenTelemetry. It ships a collector config with OTLP, Prometheus and hostmetrics receivers, batch and memory_limiter processors, plus filters that trim high-cardinality attributes. There is a Kubernetes manifest for the collector with two replicas and health probes, and a Python SDK example that sets up trace and metric exporters.

The workflow runs in order: define semantic conventions for services and environments, add the SDK or auto-instrumentation per service, run the collector to receive and export telemetry, check cardinality and sampling, then build golden-signal dashboards. Auto-instrumentation lets you attach tracing to existing services without touching their code.

You need a trace backend (Jaeger, Tempo, Datadog or any OTLP receiver) and a metrics backend (Prometheus, Mimir or an OTLP receiver) before you start. Collector deployment wants a Kubernetes cluster or a VM with systemd. Network access has to flow from services to the collector and from the collector to the backends. Skip cardinality control and storage costs climb — worth checking the filters before this reaches production.

## Requirements
- Works with: Kubernetes

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill opentelemetry -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/opentelemetry/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/opentelemetry/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill opentelemetry -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/opentelemetry/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill opentelemetry -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/opentelemetry/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install BagelHole/DevOps-Security-Agent-Skills opentelemetry
```

2. **Manually: put the files in place**
- File: `.github/skills/opentelemetry/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill opentelemetry -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/BagelHole/DevOps-Security-Agent-Skills --path devops/observability/opentelemetry
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/opentelemetry/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill opentelemetry -a opencode
```

## When to use it
- find where latency creeps in between microservices
- standardise naming across traces, metrics and logs
- ship telemetry to Prometheus, Grafana or Datadog
- add tracing to an existing service without code changes
- build golden-signal dashboards with trace-to-log correlation

## Example prompts
- set up OpenTelemetry for this Python service
- add auto-instrumentation to the existing services
- write a collector config that exports traces to Tempo and metrics to Mimir

# OpenTelemetry

Adopt vendor-neutral telemetry with consistent instrumentation across services.

## When to Use This Skill

- Debugging latency across microservices
- Standardizing observability data model and naming
- Sending telemetry to Prometheus, Grafana, Datadog, or OTLP backends
- Building SLO dashboards with trace-to-log correlation
- Instrumenting Python or Node.js applications with tracing and metrics
- Setting up auto-instrumentation for existing services without code changes

## Prerequisites

- Application services running in containers or on VMs
- Backend for traces (Jaeger, Tempo, Datadog, or any OTLP receiver)
- Backend for metrics (Prometheus, Mimir, or OTLP receiver)
- Kubernetes cluster (for collector deployment) or VM with systemd
- Network access from services to collector, and collector to backends

## Core Workflow

1. Define semantic conventions for services, environments, and versions.
2. Add SDK or auto-instrumentation in each service.
3. Run an OpenTelemetry Collector to receive, transform, and export telemetry.
4. Validate cardinality and sampling to control cost.
5. Create golden signals dashboards and alerting from collected data.

## Collector Production Configuration

```yaml
# otel-collector-config.yaml
receivers:
  otlp:
    protocols:
      grpc:
        endpoint: 0.0.0.0:4317
      http:
        endpoint: 0.0.0.0:4318

  # Scrape Prometheus endpoints
  prometheus:
    config:
      scrape_configs:
        - job_name: "kubernetes-pods"
          kubernetes_sd_configs:
            - role: pod
          relabel_configs:
            - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
              action: keep
              regex: "true"
            - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_port]
              action: replace
              target_label: __address__
              regex: (.+)
              replacement: $$1

  # Host metrics for infrastructure monitoring
  hostmetrics:
    collection_interval: 30s
    scrapers:
      cpu: {}
