What this skill does

# Datadog Audit Trail

Investigate user activity, configuration changes, access patterns, and compliance evidence using `pup audit-logs`.

## Sub-Skills

| Sub-skill | Use when |
|-----------|----------|
| **security-investigation** | "Who changed X?", "What did this user do?", "Show me deletions in the last 24h" |
| **key-compromise** | "Was this API key compromised?", "What did key XYZ do?", "Investigate suspicious key activity" |
| **cost-spike-investigation** | "Why did my bill go up?", "What caused this usage spike?", "Investigate LLM cost increase" |
| **compliance-report** | "Generate SOC 2 evidence", "PCI audit log", "User provisioning report for auditor" |
| **ai-activity-audit** | "What did the AI assistant do?", "Audit MCP tool calls", "AI governance report" |

## Prerequisites

```bash
pup auth login   # OAuth2 (recommended)
# or set DD_API_KEY + DD_APP_KEY with audit_logs_read scope
```

## Commands

```bash
# List recent events
pup audit-logs list --from 1h --limit 100

# Search with a query
pup audit-logs search --query "@action:deleted" --from 24h

# JSON output for piping to jq
pup audit-logs search --query "@usr.email:[email protected]" --from 7d -o json | jq '.data[].attributes'
```

## Event Schema Quick Reference

| Field | Description | Example values |
|-------|-------------|----------------|
| `@usr.email` | Actor email | `[email protected]` |
| `@evt.actor.type` | How action was taken | `USER`, `API_KEY`, `SUPPORT_USER` |
| `@action` | Verb | `created`, `modified`, `deleted`, `accessed`, `login` |
| `@evt.name` | Event category | `Dashboard`, `Monitor`, `Authentication`, `Access Management` |
| `@asset.type` | Resource type | `dashboard`, `monitor`, `api_key`, `role`, `user` |
| `@asset.id` | Resource identifier | `abc-123` |
| `@metadata.api_key.id` | API key used (if applicable) | `key_abc123` |
| `@metadata.app_key.id` | App key used (if applicable) | `app_abc123` |
| `@network.client.ip` | Client IP address | `1.2.3.4` |
| `@network.client.geoip.country.name` | Country | `United States` |
| `@network.client.geoip.as.name` | ASN name | `Amazon.com` |
| `@http.url_details.path` | API endpoint path | `/api/v1/dashboard/xyz` |

## Search Syntax

Same Lucene-style syntax as Log Explorer:

| Query | Meaning |
|-------|---------|
| `@evt.name:Dashboard` | Exact field match |
| `@action:deleted` | Action filter |
| `@usr.email:[email protected]` | Specific user |
| `@evt.name:Monitor AND @action:modified` | Compound |
| `-@action:deleted` | Negation |
| `@usr.email:*` | Field exists |
| `@network.client.ip:1.2.3.4` | IP filter |

## Retention

Default retention is **90 days**. If querying beyond 90 days, archive to S3/GCS/Azure Blob must be configured. Always check whether the requested time window falls within retention before running a query.

## Troubleshooting

| Problem | Cause | Fix |
|---------|-------|-----|
| 403 Forbidden | Missing `audit_logs_read` scope | Add scope to app key in Datadog UI |
| Empty results | Time window outside retention | Check archive config; default max is 90 days |
| Timeout | Query too broad | Narrow time window or add more filters |
| No IP data | Internal action or pre-enrichment event | Not all events have geo data |
