## What it does

The skill covers four log classes: `authentication`, `authorization`, `user_action` and `http`. Each one comes with its key namespaces — `audit.*`, `actor.*`, `browser.*`, `device.*`, `object.*`, `http.*`, `url.*` and others. Feed it a raw vendor payload or an already ingested event.

Three workflows. Workflow A suggests a mapping from a raw payload to `fetch logs` fields. Workflow B1 validates a mapping against a pasted event. Workflow B2 reaches into a live tenant: it pulls logs by `log.source` and runs the static check on what comes back.

Buried fields are the main thing it hunts. The skill inventories what stayed inside `content` versus what got promoted to top-level attributes, then proposes OpenPipeline extraction rules for the gaps. Load the `dt-dql-essentials` skill before touching those rules — OpenPipeline processors run on DQL functions like `parse` and `fieldsAdd`, and non-DQL syntax produces invalid rules. One more constraint from `references/openpipeline-constraints.md`: `parseJson` is unavailable, so the `parse` plus `fieldsFlatten` pair stands in for it.

## Requirements
- Works with: Dynatrace

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-log-semantic-mapping -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-log-semantic-mapping -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-log-semantic-mapping -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Dynatrace/dynatrace-for-ai dt-obs-log-semantic-mapping
```

2. **Manually: put the files in place**
- File: `.github/skills/dt-obs-log-semantic-mapping/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-log-semantic-mapping -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Dynatrace/dynatrace-for-ai --path skills/dt-obs-log-semantic-mapping
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-log-semantic-mapping -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Dynatrace/dynatrace-for-ai/tree/HEAD/skills/dt-obs-log-semantic-mapping/SKILL.md

## When to use it
- map raw vendor audit log fields onto the Dynatrace semantic dictionary
- validate an existing mapping against a pasted ingested event
- find fields buried in `content` instead of promoted to top level
- write OpenPipeline extraction rules using DQL functions
- run validation against live logs selected by `log.source`

## Example prompts
- Map this CyberArk payload to the Dynatrace semantic dictionary
- Validate my mapping against this ingested log event
- Write OpenPipeline rules for the fields still stuck in content

# dt-obs-log-semantic-mapping

Build and validate semantic-dictionary-aligned mappings for audit log integrations.

## Purpose

Use this skill when a user wants to:

- **Suggest** a mapping from a raw vendor audit log payload to Dynatrace `fetch logs` fields (Workflow A).
- **Validate** a mapping against a pasted ingested log event (Workflow B1 — static).
- **Validate** against live tenant data via live tenant access (Workflow B2 — runtime: fetches logs by `log.source`, then runs B1 on the result).

## Log Classes

| Class | Description | Key namespaces | Example sources |
|---|---|---|---|
| `authentication` | Login, logout, MFA, token | `audit.*`, `actor.*`, `browser.*`, `device.*` | CyberArk, Okta, Azure SignInLogs |
| `authorization` | Access decisions, permission changes | `audit.*`, `actor.*`, `object.*` | CyberArk, Okta |
| `user_action` | CRUD on platform resources | `audit.*`, `actor.*`, `object.*`, `product.*` | Okta, GitHub, Sonatype |
| `http` | HTTP request/response (WAF, network devices) | `http.*`, `url.*`, `server.*`, `geo.*`, `client.*` | Akamai SIEM, Cloudflare |

## Workflows

| Mode | Input | Source |
|---|---|---|
| **Workflow A** — Suggest mapping | Raw vendor log payload | `references/mapping-workflow.md § Workflow A` |
| **Workflow B1** — Static validation | Pasted ingested log event | `references/mapping-workflow.md § Workflow B1` |
| **Workflow B2** — Runtime validation | `log.source` value + live tenant access | `references/runtime-validation.md` — fetches logs, then runs B1 |

## Key Concepts

**Content field burial:** The primary validation concern. Fields in `content` (the raw vendor payload) that could be promoted to top-level semantic attributes but are not. The skill always inventories buried vs promoted fields and proposes OpenPipeline extraction rules to fix gaps.
