Monitor your Hyrex applications and implement scaling strategies for optimal performance.

​
Monitoring

​
Cloud Dashboard

Access production metrics at hyrex.io/cloud:
  • Task metrics: throughput, latency, success rates
  • Worker health: utilization, memory usage, uptime
  • Queue monitoring: depths, processing times, backlog
  • Error tracking: failure rates, error logs, alerts

​
Alerts

Configure alerts in the Hyrex Cloud dashboard:
  • High error rates
  • Queue backlog warnings
  • Worker health issues
  • Capacity thresholds

​
Scaling Strategies

​
Queue Design

Design queues based on task characteristics: 
# Separate queues by priority and resource needs
@hy.task(queue="critical", max_retries=5)
def process_payment(ctx):
    """High priority, low latency tasks"""
    pass

@hy.task(queue="batch", timeout_seconds=3600)
def generate_report(ctx):
    """Long-running batch processing"""
    pass

@hy.task(queue="io-heavy", max_concurrency=50)
def fetch_external_data(ctx):
    """I/O bound tasks that can run concurrently"""
    pass

@hy.task(queue="cpu-intensive", max_concurrency=4)
def process_images(ctx):
    """CPU bound tasks with limited concurrency"""
    pass

​
Worker Scaling

Scale workers based on queue patterns: 
# Process all queues
hyrex run-worker app:app

# Process specific queue pattern
hyrex run-worker app:app --queue_pattern "critical-*"

# Multiple workers for different workloads
hyrex run-worker app:app --queue_pattern "email-*" --num_processes 5
hyrex run-worker app:app --queue_pattern "batch-*" --num_processes 20
hyrex run-worker app:app --queue_pattern "cpu-*" --num_processes 4

Horizontal Scaling

​
Kubernetes Example

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hyrex-worker
spec:
  replicas: 3
  selector:
    matchLabels:
      app: hyrex-worker
  template:
    metadata:
      labels:
        app: hyrex-worker
    spec:
      containers:
      - name: worker
        image: myapp:latest
        env:
        - name: HYREX_API_KEY
          valueFrom:
            secretKeyRef:
              name: hyrex-secrets
              key: api-key
        resources:
          requests:
            memory: "256Mi"
            cpu: "250m"
          limits:
            memory: "512Mi" 
            cpu: "500m"

Auto-scaling Based on Queue Depth

# Custom autoscaling logic
@hy.schedule("*/2 * * * *")  # Every 2 minutes
def autoscale_workers():
    """Scale workers based on queue depth"""
    
    queue_depths = {
        "critical": hy.get_queue_depth("critical"),
        "batch": hy.get_queue_depth("batch"),
        "default": hy.get_queue_depth("default")
    }
    
    scaling_decisions = []
    
    for queue, depth in queue_depths.items():
        if depth > 100:
            # Scale up
            scaling_decisions.append({
                "queue": queue,
                "action": "scale_up",
                "target_workers": min(10, depth // 20)
            })
        elif depth < 10:
            # Scale down
            scaling_decisions.append({
                "queue": queue,
                "action": "scale_down", 
                "target_workers": max(1, depth // 5)
            })
    
    return {
        "timestamp": time.time(),
        "queue_depths": queue_depths,
        "scaling_decisions": scaling_decisions
    }

Performance Optimization

​
Task Optimization

# Optimize task performance
@hy.task(
    queue="optimized",
    timeout_seconds=60,
    max_retries=3,
    retry_delay_seconds=5
)
def optimized_task(ctx):
    """Well-optimized task"""
    
    # Use connection pooling
    with get_db_connection() as conn:
        # Batch operations when possible
        results = conn.execute_batch(queries)
    
    # Process in chunks to manage memory
    for chunk in chunked_data(ctx.data, chunk_size=1000):
        process_chunk(chunk)
    
    return {"processed": len(ctx.data)}

​
Resource Monitoring

import psutil
import gc

@hy.task
def resource_aware_task(ctx):
    """Monitor and optimize resource usage"""
    
    # Check memory usage
    memory_percent = psutil.virtual_memory().percent
    if memory_percent > 80:
        gc.collect()  # Force garbage collection
        logging.warning(f"High memory usage: {memory_percent}%")
    
    # Your task logic here
    result = process_data(ctx)
    
    return {
        "result": result,
        "memory_usage": psutil.virtual_memory().percent,
        "cpu_usage": psutil.cpu_percent()
    }
