+# Metrics and Telemetry Guide
+
+## Overview
+
+The wikijs-python-sdk includes built-in metrics collection for monitoring performance and reliability.
+
+## Basic Usage
+
+```python
+from wikijs import WikiJSClient
+
+# Create client with metrics enabled (default)
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    enable_metrics=True
+)
+
+# Perform operations
+pages = client.pages.list()
+page = client.pages.get(123)
+
+# Get metrics
+metrics = client.get_metrics()
+print(f"Total requests: {metrics['total_requests']}")
+print(f"Error rate: {metrics['error_rate']:.2f}%")
+print(f"Avg latency: {metrics['latency']['avg']:.2f}ms")
+print(f"P95 latency: {metrics['latency']['p95']:.2f}ms")
+```
+
+## Available Metrics
+
+### Counters
+- `total_requests`: Total API requests made
+- `total_errors`: Total errors (4xx, 5xx responses)
+- `total_server_errors`: Server errors (5xx responses)
+
+### Latency Statistics
+- `min`: Minimum request duration
+- `max`: Maximum request duration
+- `avg`: Average request duration
+- `p50`: 50th percentile (median)
+- `p95`: 95th percentile
+- `p99`: 99th percentile
+
+### Error Rate
+- Percentage of failed requests
+
+## Example Output
+
+```python
+{
+    "total_requests": 150,
+    "total_errors": 3,
+    "error_rate": 2.0,
+    "latency": {
+        "min": 45.2,
+        "max": 523.8,
+        "avg": 127.3,
+        "p50": 98.5,
+        "p95": 312.7,
+        "p99": 487.2
+    },
+    "counters": {
+        "total_requests": 150,
+        "total_errors": 3,
+        "total_server_errors": 1
+    },
+    "gauges": {}
+}
+```
+
+## Advanced Usage
+
+### Custom Metrics
+
+```python
+from wikijs.metrics import get_metrics
+
+metrics = get_metrics()
+
+# Increment custom counter
+metrics.increment("custom_operation_count", 5)
+
+# Set gauge value
+metrics.set_gauge("cache_hit_rate", 87.5)
+
+# Get statistics
+stats = metrics.get_stats()
+```
+
+### Reset Metrics
+
+```python
+metrics = get_metrics()
+metrics.reset()
+```
+
+## Monitoring Integration
+
+Metrics can be exported to monitoring systems:
+
+```python
+import json
+
+# Export metrics as JSON
+metrics_json = json.dumps(client.get_metrics())
+
+# Send to monitoring service
+# send_to_datadog(metrics_json)
+# send_to_prometheus(metrics_json)
+```
+
+## Best Practices
+
+1. Monitor error rates regularly
+2. Set up alerts for high latency (p95 > threshold)
+3. Track trends over time
+4. Reset metrics periodically
+5. Export to external monitoring systems

+# Rate Limiting Guide
+
+## Overview
+
+The wikijs-python-sdk includes built-in rate limiting to prevent API throttling and ensure stable operation.
+
+## Basic Usage
+
+```python
+from wikijs import WikiJSClient
+
+# Create client with rate limiting (10 requests/second)
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    rate_limit=10.0
+)
+
+# API calls will be automatically rate-limited
+pages = client.pages.list()  # Throttled if necessary
+```
+
+## Configuration
+
+### Global Rate Limit
+
+```python
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    rate_limit=5.0,  # 5 requests per second
+    rate_limit_timeout=60.0  # Wait up to 60 seconds
+)
+```
+
+### Without Rate Limiting
+
+```python
+# Disable rate limiting (use with caution)
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    rate_limit=None
+)
+```
+
+## How It Works
+
+The rate limiter uses a **token bucket algorithm**:
+
+1. Tokens refill at a constant rate (requests/second)
+2. Each request consumes one token
+3. If no tokens available, request waits
+4. Burst traffic is supported up to bucket size
+
+## Per-Endpoint Rate Limiting
+
+For advanced use cases:
+
+```python
+from wikijs.ratelimit import PerEndpointRateLimiter
+
+limiter = PerEndpointRateLimiter(default_rate=10.0)
+
+# Set custom rate for specific endpoint
+limiter.set_limit("/graphql", 5.0)
+
+# Acquire permission
+if limiter.acquire("/graphql", timeout=10.0):
+    # Make request
+    pass
+```
+
+## Timeout Handling
+
+```python
+from wikijs import WikiJSClient
+
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    rate_limit=1.0,
+    rate_limit_timeout=5.0
+)
+
+try:
+    # This may raise TimeoutError if rate limit exceeded
+    result = client.pages.list()
+except TimeoutError as e:
+    print("Rate limit timeout exceeded")
+```
+
+## Best Practices
+
+1. **Set appropriate limits**: Match your Wiki.js instance capabilities
+2. **Monitor rate limit hits**: Track timeout errors
+3. **Use burst capacity**: Allow short bursts of traffic
+4. **Implement retry logic**: Handle timeout errors gracefully
+5. **Test limits**: Validate under load
+
+## Recommended Limits
+
+- **Development**: 10-20 requests/second
+- **Production**: 5-10 requests/second
+- **High-volume**: Configure based on Wiki.js capacity
+- **Batch operations**: Lower rate (1-2 requests/second)
+
+## Example: Batch Processing
+
+```python
+from wikijs import WikiJSClient
+import time
+
+client = WikiJSClient(
+    "https://wiki.example.com",
+    auth="your-api-key",
+    rate_limit=2.0  # Conservative rate for batch
+)
+
+page_ids = range(1, 101)
+results = []
+
+for page_id in page_ids:
+    try:
+        page = client.pages.get(page_id)
+        results.append(page)
+    except TimeoutError:
+        print(f"Rate limit timeout for page {page_id}")
+    except Exception as e:
+        print(f"Error processing page {page_id}: {e}")
+
+print(f"Processed {len(results)} pages")
+```
+
+## Monitoring
+
+Combine with metrics to track rate limiting impact:
+
+```python
+metrics = client.get_metrics()
+print(f"Requests: {metrics['total_requests']}")
+print(f"Avg latency: {metrics['latency']['avg']}")
+# Increased latency may indicate rate limiting
+```
