LogTail Smart Log Monitor & Analyzer

LogTail Smart Log Monitor & Analyzer

Monitor log files in real-time. Filter noise, surface errors, summarize patterns, alert on anomalies. Makes logs readable.

Logs are noisy. LogTail finds the signal.

Usage

const { LogTail } = require('./src/log-tail');
const tail = new LogTail({
  files: ['./logs/app.log', './logs/error.log'],
  filters: {
    ignore: ['DEBUG', 'health_check'],
    highlight: ['ERROR', 'FATAL', 'timeout']
  }
});
tail.watch((entry) => {
  if (entry.severity === 'error') console.log('🔴', entry.message);
});
const summary = await tail.summarize({ period: '1h' });
