IIS Inspector provides a comprehensive solution for capturing detailed metrics for each request without relying on log files, opting for ETW instead. It records not just execution time but also the flush time, which is how long it takes to deliver a response to the client. Additionally, it tracks crucial performance indicators such as CPU usage, memory consumption, .NET exceptions, application pool recycles, bandwidth usage, and more. This tool allows users to thoroughly assess the performance of any website hosted on IIS, whether it runs on ASP.NET or PHP. The data collected by IIS Inspector is reported directly to Elasticsearch, facilitating visualization through Kibana. While it includes default visualizations, users have the flexibility to create their own tailored views. With Kibana's capabilities, users can effortlessly discover and visualize detailed request data collected by IIS Inspector. Moreover, it enables the creation of custom alerts utilizing Elasticsearch's watcher feature, and several predefined watch definitions are available to streamline the initial setup. In addition to performance metrics, IIS Inspector provides insights into what Microsoft IIS is caching and compressing, ensuring that you have a full understanding of your web server's operation. Overall, this tool empowers administrators to optimize their web applications effectively.
