from foundry_tools.cache import CacheConfig, CacheStrategy

cache_config = CacheConfig(
    strategy=CacheStrategy.LRU,
    max_size=1000,
    ttl=3600,  # 1 hour
    key_generator="content_hash"
)

# Apply to specific tools
@FoundryTool(
    name="cached_analyzer",
    cache_config=cache_config
)
async def cached_code_analyzer(code: str) -> Dict[str, Any]:
    # Expensive analysis that benefits from caching
    pass
```

### 2. Mallipoolin hallinta
```python
from foundry_tools.pool import ModelPoolConfig

pool_config = ModelPoolConfig(
    models={
        "phi-4-mini": {"instances": 2, "priority": "high"},
        "qwen2.5-coder-0.5b": {"instances": 1, "priority": "medium"},
        "phi-3.5-mini": {"instances": 1, "priority": "low"}
    },
    load_balancing="round_robin",
    health_check_interval=30
)

# Configure tool registry with pool
registry = FoundryToolRegistry(model_pool_config=pool_config)
```

### 3. Eräkäsittely
```python
from foundry_tools.batch import BatchProcessor

@BatchProcessor(
    batch_size=10,
    timeout=60,
    parallel_batches=3
)
async def batch_code_analysis(code_files: List[str]) -> List[Dict[str, Any]]:
    """Process multiple code files in batches."""
    results = []
    
    for code_file in code_files:
        with open(code_file, 'r') as f:
            code = f.read()
        
        result = await call_tool("code_analyzer", code=code)
        results.append(result)
    
    return results
```

## Seuranta ja havainnointi

### 1. Työkalumetriikat
```python
from foundry_tools.monitoring import ToolMetrics

# Automatic metrics collection
metrics = await ToolMetrics.get_tool_performance("code_analyzer")
print(f"Average execution time: {metrics.avg_execution_time}s")
print(f"Success rate: {metrics.success_rate}%")
print(f"Cache hit rate: {metrics.cache_hit_rate}%")
```

### 2. Terveydentilan seuranta
```python
from foundry_tools.health import HealthMonitor

health_monitor = HealthMonitor()

# Monitor tool health
health_status = await health_monitor.check_all_tools()
print(f"Healthy tools: {health_status.healthy_count}")
print(f"Failed tools: {health_status.failed_tools}")
```

### 3. Käyttöanalytiikka
```python
from foundry_tools.analytics import UsageAnalytics

analytics = UsageAnalytics()

# Track tool usage patterns
usage_report = await analytics.generate_usage_report(
    start_date="2024-01-01",
    end_date="2024-01-31"
)

print(f"Most used tool: {usage_report.most_used_tool}")
print(f"Peak usage time: {usage_report.peak_usage_time}")
```
