Managing App Services
This section guides you through the essential operations for managing your deployed App Services. Learn how to monitor performance, scale resources, configure settings, and deploy updates effectively.
Monitoring App Service Performance
Effective monitoring is crucial for maintaining the health and performance of your application. The App Service portal provides a comprehensive dashboard with key metrics.
- CPU Usage: Track the percentage of CPU utilized by your service.
- Memory Usage: Monitor the amount of RAM your service is consuming.
- Network In/Out: Observe the data transfer rates for your service.
- Request Count: See the number of incoming requests your service is handling.
- Error Rate: Identify and track HTTP errors (e.g., 5xx, 4xx).
You can set up alerts based on these metrics to be notified of potential issues proactively.
Key Monitoring APIs
GET /appservices/{id}/metrics: Retrieves performance metrics for a specific app service.GET /appservices/{id}/logs: Fetches application and web server logs.POST /appservices/{id}/alerts: Configures custom alerts for performance thresholds.
Scaling App Services
As your application's traffic grows, you may need to scale your App Services to ensure optimal performance and availability. App Services support both vertical and horizontal scaling.
Vertical Scaling (Scale Up/Down)
This involves changing the instance size of your App Service to provide more CPU, memory, or disk space. You can easily adjust the tier of your App Service through the portal.
Horizontal Scaling (Scale Out/In)
This involves increasing or decreasing the number of instances running your App Service. This is ideal for handling increased traffic loads.
Configuring App Service Settings
App Services offer a wide range of configuration options to tailor your application's environment.
- Connection Strings: Securely store and manage database and other service connection strings.
- App Settings: Define custom environment variables and application-specific configurations.
- General Settings: Configure runtime stack, platform version, and deployment slots.
- Custom Domains: Map your custom domain names to your App Service.
- SSL Certificates: Secure your application with SSL/TLS certificates.
Deploying Updates and Managing Deployment Slots
Deployment slots allow you to manage deployments with zero downtime. You can deploy a new version of your app to a staging slot, test it thoroughly, and then swap it with the production slot.
- Create Deployment Slots: Add new slots for staging, testing, or canary releases.
- Swap Slots: Seamlessly swap content and configuration between slots.
- Auto Swap: Configure automatic swapping when a new deployment is ready.
This feature is invaluable for ensuring smooth transitions and minimizing the risk of introducing bugs into your production environment.
