Analyze log files to troubleshoot errors, identify peak error periods, and produce error clustering, frequency statistics, and time distribution reports. Supports JSON, syslog, and Nginx formats with automatic detection. Use when a user uploads a .log file and asks to analyze errors, find patterns, debug issues, or get distribution stats.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Log Error Digest
Automated log file analysis that produces error clustering, frequency statistics, and time distribution reports.
## Features
- **Error Clustering**: Groups similar error messages by normalizing dynamic parts (IPs, UUIDs, numbers, etc.) to identify root causes
- **Frequency Statistics**: Counts occurrences by error type, sorted by severity
- **Time Distribution**: Shows error distribution by hour and by date, helping pinpoint peak error periods
## Supported Log Formats
| Format | Description | Auto-detection |
|--------|-------------|----------------|
| JSON | One JSON object per line with `timestamp`/`level`/`message` fields | Starts with `{` |
| syslog | RFC 3164 format, e.g. `Jan 1 12:00:00 host proc[pid]: msg` | Starts with month name |
| Nginx | Access log or error log format | Starts with IP or date/path pattern |
## Usage
```bash
python scripts/analyze_logs.py <log_file_path> [options]
```
### Parameters
| Parameter | Description | Default |
|-----------|-------------|---------|
| `log_file` | Path to the log file (required) | - |
| `--format` | Log format: `auto`/`json`/`syslog`/`nginx` | `auto` |
| `--top` | Show Top N error clusters | `20` |

How to install
mdr add zebbern/claude-code-guide/log-error-digest@sha256:a76b63daae699f2bThe line at the top of this page pins the label git:20260531.164971d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
