How to Implement Production Monitoring for Saros Applications

Production Monitoring for Saros Applications

Goal: Implement comprehensive monitoring that prevents costly failures and ensures optimal user experience

Production DeFi applications require robust monitoring to detect issues before they impact users. This guide provides battle-tested monitoring strategies used by successful Saros-powered applications handling millions in daily volume.

    };

    // Listen for alerts
    const handleAlert = (alert: any) => {
      setAlerts(prev => [alert, ...prev].slice(0, 10)); // Keep last 10 alerts
    };

    sarosMetrics.on('alert', handleAlert);

    return () => {

// api/health.ts
import { sarosMetrics } from '../monitoring/SarosMetrics';

export default async function healthHandler(req: any, res: any) {
  try {
    const metrics = sarosMetrics.getBusinessMetrics('hour');
    
    // Define health criteria
    const isHealthy = 
      metrics.successRate > 0.95 && // 95% success rate
      metrics.averageLatency < 10000 && // Under 10s average latency
      metrics.totalSwaps > 0; // At least some activity

    const status = isHealthy ? 'healthy' : 'unhealthy';
    const httpStatus = isHealthy ? 200 : 503;

    const response = {
      status,
      timestamp: new Date().toISOString(),
      metrics: {
        successRate: metrics.successRate,
        averageLatency: metrics.averageLatency,
        totalSwaps: metrics.totalSwaps,
        uptime: process.uptime()
      },
      checks: {
        database: await checkDatabase(),
        rpc: await checkRPC(),
        cache: await checkCache()
      }
    };

    res.status(httpStatus).json(response);
    
  } catch (error) {
    res.status(503).json({
      status: 'unhealthy',
      error: error.message,
      timestamp: new Date().toISOString()
    });
  }
}

async function checkDatabase(): Promise<boolean> {
  // Implement database health check
  return true;
}

async function checkRPC(): Promise<boolean> {
  // Implement RPC health check
  try {
    const start = Date.now();
    // Your RPC health check logic
    const latency = Date.now() - start;
    return latency < 5000;
  } catch {

  }
}

async function checkCache(): Promise<boolean> {
  // Implement cache health check
  return true;
}

Risk Management Framework

Comprehensive risk controls for trading systems - this framework ensures your production systems have proper safeguards

Production Deployment Checklist

✅ Monitoring Infrastructure

Metrics collection implemented
Alerting channels configured
Dashboard deployed and accessible
Health check endpoints working

✅ Alert Configuration

Success rate < 95% → Critical alert
Average latency > 10s → Warning alert
Price impact > 5% → Warning alert
Pool TVL < $50k → Warning alert
RPC latency > 5s → Critical alert

✅ Business Metrics

Daily/weekly volume tracking
User retention metrics
Revenue/fee tracking
Cost per transaction analysis

✅ Security Monitoring

Failed authentication attempts
Unusual transaction patterns
API rate limiting alerts
Large transaction alerts

This monitoring setup provides comprehensive visibility into your Saros application’s performance, enabling proactive issue resolution and optimal user experience in production.
