System Monitoring Setup

Ubuntu Monitoring Configuration:

bash

# Install monitoring tools
sudo apt install -y prometheus node-exporter grafana
# Configure Prometheus
sudo cat > /etc/prometheus/prometheus.yml << 'EOF'
global:
  scrape_interval: 15s
scrape_configs:
  - job_name: 'flowise'

# Start monitoring services
sudo systemctl enable prometheus grafana-server node-exporter

npm install --save prom-client
# Create metrics configuration
cat > ~/flowise-metrics.js << 'EOF'
const client = require('prom-client');
// Create custom metrics
const httpRequestDuration = new client.Histogram({
  name: 'flowise_http_request_duration_seconds',
  help: 'Duration of HTTP requests in seconds',
  labelNames: ['method', 'status_code']

  help: 'Total number of active flows'
});
const apiCalls = new client.Counter({
  name: 'flowise_api_calls_total',
  help: 'Total number of API calls',
  labelNames: ['endpoint', 'method']
});
// Export metrics
module.exports = {
  httpRequestDuration,
  activeFlows,
