## What it does

The skill hands the agent ready DQL patterns for Dynatrace logs. Fetch over a time window, filter by severity (`ERROR`, `FATAL`, `WARN`), search message text with `contains()` or `matchesPhrase()`, group by process group through `dt.process_group.detected_name`.

Structured logs get their own section. When an app emits JSON lines, `parse content, "JSON:log"` pulls out fields like `level`, `msg` and `error`, and you can aggregate on those. Worked examples cover error rate per five-minute bucket and the most frequent error messages.

One catch worth knowing before you write anything: if a query has to join logs with host attributes — OS type, hostname, IP, cloud provider — the skill says to read `dt-dql-essentials/references/smartscape-topology-navigation.md` first. Skip that and the cross-source join won't come together. Tracing and span analysis sit outside this skill; that's `dt-obs-tracing`.

## Requirements
- Works with: Dynatrace

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/dt-obs-logs/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-logs
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-logs -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-logs/SKILL.md

## When to use it
- find all errors in the logs from the last hour
- compute error rate per five-minute bucket
- list the most frequent error messages over a day
- parse JSON log lines into separate fields
- filter one process group's logs by severity

## Example prompts
- show error logs from the last hour
- calculate log error rate over 2 hours in 5-minute buckets
- find top error messages from the last 24h and parse the JSON logs

# Log Analysis Skill

Query, filter, and analyze Dynatrace log data using DQL for troubleshooting and monitoring.

## What This Skill Covers

- Fetching and filtering logs by severity, content, and entity
- Searching log messages using pattern matching
- Calculating error rates and statistics
- Analyzing log patterns and trends
- Grouping and aggregating log data by dimensions

> **Cross-source join required:** If the query must combine logs with host attributes
> (OS type, hostname, IP address, cloud provider) → also read
> `dt-dql-essentials/references/smartscape-topology-navigation.md` before writing the query.

---

## Use Cases
Use this skill when users want to:
- Find specific log entries (e.g., "show me error logs from the last hour")
- Filter logs by severity, process group, or content
- Search logs for specific keywords or phrases
- Calculate error rates or log statistics
- Identify common error messages or patterns
- Analyze log trends over time
- Troubleshoot issues using log data

## Key Concepts

### Log Data Model
- **timestamp**: When the log entry was created
- **content**: The log message text
- **status**: Log level (ERROR, FATAL, WARN, INFO, etc.)
- **dt.process_group.id**: Associated process group entity
- **dt.process_group.detected_name**: Resolves process group IDs to human-readable names

### Query Patterns
- **fetch logs**: Primary command for log data access
- **Time ranges**: Use `from:now() - <duration>` for time windows
- **Filtering**: Apply severity, content, and entity filters
- **Aggregation**: Group and summarize log data
- **Pattern Detection**: Use `matchesPhrase()` and `contains()` for content search

### Common Operations
- Severity filtering (single or multiple levels)
- Content search (simple and full-text)
- Entity-based filtering (process groups)
- Time-series analysis (bucketing, sorting)
- Error rate calculation
- Pattern analysis (exceptions, timeouts, etc.)

## Core Workflows

### 1. Log Searching
Find specific log entries by time, severity, and content.

**Typical steps**:
1. Define time range
2. Filter by severity (optional)
3. Search content for keywords
4. Select relevant fields
5. Sort and limit results

**Example**:
```dql
fetch logs, from:now() - 1h
````
