In Part 2 of this series, we learned how to access IIS metrics and logs using Windows tools. In this post, we’ll show you a more comprehensive approach to IIS monitoring, one that brings together out-of-the-box dashboards, automated alerts, and log analytics, all in a single platform.

In this post, we’ll show you how to use built-in IIS monitoring tools to access and graph performance counters, configure logging in IIS, and query your logs with Microsoft’s Log Parser Studio. We’ll also explain how to use a diagnostic tool to investigate memory leaks and high CPU utilization in your application pools and worker processes.

Microsoft’s Internet Information Services (IIS) is a web server that has traditionally come bundled with Windows (e.g., versions 5.0, 6.0, and beyond). IIS has numerous extensibility features. Swappable interfaces like ISAPI and FastCGI make it possible to use IIS with a variety of backend technologies, from micro-frameworks like Flask to runtimes like Node.js, along with technologies you’d expect to find within a Windows-based production environment (e.g., ASP.NET).

Windows hosts make up a significant portion of the infrastructure of many organizations, and visibility into Windows systems can be a vital observability need. We’re pleased to announce that Datadog’s Live Process monitoring is now available for Windows.

Node.js is an asynchronous JavaScript runtime that is used to develop highly scalable network applications. To help provide more visibility into these dynamic environments, we’re pleased to announce that Datadog APM has officially released support for monitoring Node.js applications, which joins our existing support for Java, Ruby, Python and Go.
