Standard availability tests in Application Insights have limitations like no multi-step authentication, no mTLS support and no access to private networks. This post shows you how to create custom availability tests using .NET and Azure Functions to overcome these restrictions while gaining full control over your monitoring logic.
When connecting to external systems in integration projects, availability tests help you monitor system uptime, verify security measures are up to date and confirm systems can be reached. This post shows you how to create Application Insights standard tests through Bicep to automate your availability monitoring with infrastructure-as-code.
Learn how to use Azure API Management’s rate-limit and rate-limit-by-key policies to protect backends from overwhelming traffic and fairly distribute capacity among clients. Includes practical examples, monitoring guidance and key considerations for different scenarios.
Sometimes you just want to forward any request from Azure API Management to a backend without defining a detailed API contract. In this post I show how to create a simple Catch-All API that supports multiple HTTP methods and matches any URL.
Learn how to implement centralized error handling in Azure API Management at the global scope, reducing duplicate logic and ensuring consistent error responses across all APIs while maintaining flexibility for custom scenarios.
By default, Azure API Management returns all headers from the backend to the client, which may include sensitive information. This post demonstrates three approaches to sanitizing response headers: explicit removal, allowlist-based filtering and blocklist-based filtering.
