Protocol Configuratie

​

HTTP/HTTPS Services

​

Basis Configuratie

​

Geavanceerde Opties

• Expected Response: Verwachte JSON response voor health checks

Monitoring Dashboard

​

Service Status Overview

• 🟢 Up: Service responding normally
• 🔴 Down: Service niet bereikbaar of geeft errors
• 🟡 Degraded: Service traag of gedeeltelijk werkend
• ⚫ Unknown: Status onbekend (tijdens eerste checks)

​

Real-time Metrics

• Response Time: Gemiddelde response tijd per protocol
• Uptime Percentage: Service beschikbaarheid
• Error Rate: Percentage failed checks
• Last Check: Timestamp van laatste check

​

Historische Data

• 24h Uptime Graph: Uptime over afgelopen 24 uur
• Response Time Trends: Performance trends
• Error Patterns: Wanneer en waarom services falen
• Incident History: Vorige downtime incidenten

​

API Integration

# Alle services ophalen
curl -H "Authorization: Bearer YOUR_TOKEN" https://api.ipulse.one/services

# Nieuwe service toevoegen
curl -X POST https://api.ipulse.one/services \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "API Health Check",
    "protocol": "https",
    "protocolConfig": {
      "host": "api.example.com",
      "port": 443,
      "path": "/health"
    },
    "checkInterval": 5
  }'

# Service status controleren
curl -H "Authorization: Bearer YOUR_TOKEN" https://api.ipulse.one/services/SERVICE_ID

# Handmatige check uitvoeren
curl -X POST https://api.ipulse.one/services/SERVICE_ID/check \
  -H "Authorization: Bearer YOUR_TOKEN"

​

Troubleshooting

​

Veelvoorkomende Problemen

• Controleer firewall instellingen
• Verificeer dat service draait op gespecificeerde poort
• Controleer network connectivity van monitoring locaties

• Verificeer credentials
• Controleer of account actief is
• Test handmatig met dezelfde credentials

• Update expected response configuration
• Controleer API documentation van service
• Gebruik flexible response matching

• Controleer certificaat validiteit
• Verificeer hostname matching
• Update cipher suite ondersteuning

​

Best Practices

1. Realistische Timeouts: Stel timeouts in gebaseerd op service performance
2. Appropriate Intervals: Gebruik niet te frequente checks voor kritieke services
3. Content Validation: Gebruik expected responses voor accurate health checks
4. Maintenance Windows: Stel maintenance schedules in om false alerts te voorkomen
5. Regional Monitoring: Gebruik multi-location monitoring voor geografisch distributeerde services

​

Performance Optimization

1. Batch Checks: Gebruik lagere intervals voor non-critical services
2. Smart Alerting: Configureer alerts alleen voor echte problemen
3. Resource Limits: Stel rate limits in voor API endpoints
4. Caching: Cache responses waar mogelijk voor betere performance

​

Security Considerations

1. Credential Management: Gebruik dedicated monitoring accounts met minimale privileges
2. Network Security: Beperk monitoring toegang tot trusted IP ranges
3. Data Encryption: Gebruik HTTPS waar mogelijk
4. Audit Logging: Controleer service access logs voor security events
