logsentry

Logging quality & observability analyzer -- detects missing structured logging, sensitive data in logs, inconsistent log levels, and log injection vulnerabilities

LogSentry -- Logging Quality & Observability Analyzer

LogSentry scans codebases for logging anti-patterns, missing structured logging, sensitive data exposure in log output, inconsistent log levels, missing correlation IDs, and log injection vulnerabilities. It uses regex-based pattern matching against 90 logging-specific patterns across 6 categories, lefthook for git hook integration, and produces markdown reports with actionable remediation guidance. 100% local. Zero telemetry.

Commands

Free Tier (No license required)

logsentry scan [file|directory]

One-shot logging quality scan of files or directories.

How to execute:

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [target]

What it does:

1. Accepts a file path or directory (defaults to current directory)
2. Discovers all source files (skips .git, node_modules, binaries, images, .min.js)
3. Runs 30 logging quality patterns against each file (free tier limit)
4. Calculates a logging quality score (0-100) per file and overall
5. Grades: A (90-100), B (80-89), C (70-79), D (60-69), F (<60)
6. Outputs findings with: file, line number, check ID, severity, description, recommendation
7. Exit code 0 if score >= 70, exit code 1 if logging quality is poor
8. Free tier limited to first 30 patterns (SL + LL categories)

Example usage scenarios:

• "Scan my code for logging issues" -> runs logsentry scan .
• "Check this file for logging anti-patterns" -> runs logsentry scan src/server.ts
• "Find sensitive data in my logs" -> runs logsentry scan src/
• "Audit logging quality in my project" -> runs logsentry scan .
• "Check for log injection vulnerabilities" -> runs logsentry scan .

Pro Tier ($19/user/month -- requires LOGSENTRY_LICENSE_KEY)

logsentry scan --tier pro [file|directory]

Extended scan with 60 patterns covering structured logging, log levels, sensitive data, and log injection.

How to execute:

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [target] --tier pro

What it does:

1. Validates Pro+ license
2. Runs 60 logging patterns (SL, LL, SD, LI categories)
3. Detects sensitive data in logs (passwords, tokens, PII)
4. Identifies log injection vulnerabilities
5. Full category breakdown reporting

logsentry scan --format json [directory]

Generate JSON output for CI/CD integration.

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --format json

logsentry scan --format html [directory]

Generate HTML report for browser viewing.

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --format html

logsentry scan --category SD [directory]

Filter scan to a specific check category (SL, LL, SD, LI, CI, OB).

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --category SD

Team Tier ($39/user/month -- requires LOGSENTRY_LICENSE_KEY with team tier)

logsentry scan --tier team [directory]

Full scan with all 90 patterns across all 6 categories including correlation IDs and observability.

How to execute:

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --tier team

What it does:

1. Validates Team+ license
2. Runs all 90 patterns across 6 categories
3. Includes correlation/context checks (missing request IDs, trace IDs)
4. Includes observability checks (missing metrics, health checks, audit trails)
5. Full category breakdown with per-file results

logsentry scan --verbose [directory]

Verbose output showing every matched line and pattern details.

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [directory] --verbose

logsentry status

Show license and configuration information.

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" status

Check Categories

LogSentry detects 90 logging anti-patterns across 6 categories:

Category	Code	Patterns	Description	Severity Range
Structured Logging	SL	15	Missing structured logging, print/println instead of loggers, string concatenation in log messages, missing log context fields	medium -- high
Log Levels	LL	15	Incorrect log level usage, debug in production, missing error-level for exceptions, inconsistent level patterns	low -- high
Sensitive Data	SD	15	Passwords/tokens/PII in log output, logging request bodies, credit card patterns, SSN/email exposure	high -- critical
Log Injection	LI	15	Unsanitized user input in logs, newline injection, CRLF attacks, format string vulnerabilities	high -- critical
Correlation & Context	CI	15	Missing request/trace IDs, missing correlation IDs, no structured context, inconsistent timestamp formats	low -- medium
Observability	OB	15	Missing metrics emission, no health check logging, missing audit trail events, absent error rate tracking	low -- medium

Tier-Based Pattern Access

Tier	Patterns	Categories
Free	30	SL, LL
Pro	60	SL, LL, SD, LI
Team	90	SL, LL, SD, LI, CI, OB
Enterprise	90	SL, LL, SD, LI, CI, OB + priority support

Scoring

LogSentry uses a deductive scoring system starting at 100 (perfect):

Severity	Point Deduction	Description
Critical	-25 per finding	Severe security issue (sensitive data exposure, injection)
High	-15 per finding	Significant quality problem (missing loggers, concatenation)
Medium	-8 per finding	Moderate concern (debug levels, missing context)
Low	-3 per finding	Informational / best practice suggestion

Grading Scale

Grade	Score Range	Meaning
A	90-100	Excellent logging quality
B	80-89	Good logging with minor issues
C	70-79	Acceptable but needs improvement
D	60-69	Poor logging quality
F	Below 60	Critical logging problems

• Pass threshold: 70 (Grade C or better)
• Exit code 0 = pass (score >= 70)
• Exit code 1 = fail (score < 70)

Configuration

Users can configure LogSentry in ~/.openclaw/openclaw.json:

json

{
  "skills": {
    "entries": {
      "logsentry": {
        "enabled": true,
        "apiKey": "YOUR_LICENSE_KEY_HERE",
        "config": {
          "severityThreshold": "medium",
          "ignorePatterns": ["**/test/**", "**/fixtures/**", "**/*.test.*"],
          "ignoreChecks": [],
          "reportFormat": "text"
        }
      }
    }
  }
}

Important Notes

• Free tier works immediately with no configuration
• All scanning happens locally -- no code is sent to external servers
• License validation is offline -- no phone-home or network calls
• Pattern matching only -- no AST parsing, no external dependencies beyond bash
• Supports scanning all file types in a single pass
• Git hooks use lefthook which must be installed (see install metadata above)
• Exit codes: 0 = pass (score >= 70), 1 = fail (for CI/CD integration)
• Output formats: text (default), json, html

Error Handling

• If lefthook is not installed and user tries hooks, prompt to install it
• If license key is invalid or expired, show clear message with link to https://logsentry.pages.dev/renew
• If a file is binary, skip it automatically with no warning
• If no scannable files found in target, report clean scan with info message
• If an invalid category is specified with --category, show available categories
