It automatically detects log formats, identifies error patterns, and provides intelligent insights with severity classifications. +A powerful CLI tool for parsing, analyzing, and providing intelligent summaries of log files. LogLens detects error patterns, highlights anomalies, and outputs human-readable reports with severity classifications and suggested fixes. ## Features -- **Multi-format Support**: Parse JSON, syslog, Apache/Nginx, and raw logs -- **Smart Error Detection**: Built-in patterns for common error types -- **Severity Classification**: Categorize issues as critical, error, warning, info, or debug -- **Interactive Analysis**: Analyze logs interactively or in batch mode -- **Rich Output**: Beautiful terminal tables with color-coded severity levels -- **Flexible Output**: Export results as tables, JSON, or plain text -- **Pipe Support**: Process logs from stdin for real-time analysis +- **Multi-format Log Parsing**: Support for JSON, syslog (RFC 3164/5424), and Apache/Nginx logs +- **Error Pattern Detection**: Built-in library of 20+ patterns for common errors (exceptions, stack traces, connection failures) +- **Severity Classification**: Automatic classification into Critical, Error, Warning, Info, and Debug levels +- **Real-time Analysis**: Pipe support for live log streaming with `--follow` mode +- **Human-readable Reports**: Beautiful table and text outputs with color coding +- **Unix Tool Integration**: Works seamlessly with grep, sed, and other command-line tools ## Installation ### From Source ```bash +git clone https://7000pct.gitea.bloupla.net/7000pctAUTO/loglens-cli.git +cd loglens-cli pip install -e . ``` @@ -26,157 +27,365 @@ pip install -e . pip install loglens-cli ``` +### Development Installation + +```bash +pip install -e ".[dev]" +``` + +## Quick Start + +### Analyze a log file + +```bash +# Auto-detect format and analyze +loglens analyze app.log + +# Specify format explicitly +loglens analyze app.log --format json +loglens analyze app.log --format syslog +loglens analyze app.log --format apache + +# Show detailed output +loglens analyze app.log --verbose +``` + +### Watch logs in real-time + +```bash +# Follow log file updates +loglens watch /var/log/app.log + +# Follow with auto-refresh +loglens watch /var/log/app.log --interval 2 +``` + +### Generate summary reports + +```bash +# Generate summary report +loglens report app.log + +# Generate report with severity breakdown +loglens report app.log --severity + +# JSON output for programmatic use +loglens report app.log --json +``` + +### Check detected patterns + +```bash +# List all available patterns +loglens patterns + +# Search for specific patterns +loglens patterns --search "connection" + +# Show pattern details +loglens patterns --show-exceptions +``` + +### Pipe support + +```bash +# Process logs from stdin +tail -f app.log | loglens analyze -
