Microsoft IIS integration

If you’re running web applications on Windows, IIS is likely your web server, and this integration gives you the visibility you need. It collects metrics through Windows performance counters, the same mechanism Windows itself uses, so you’re getting authoritative data. Request rates, active connections, bytes transferred, response times.

Application pool monitoring is where this integration really shines. IIS isolates applications in pools, and each pool can have its own problems. You need visibility into worker process health, memory usage, and resource consumption per pool.

Request queue length is a critical metric: when it grows, IIS can’t keep up with incoming traffic, and users experience delays.

The integration typically runs alongside the Windows integration. You get host-level metrics from Windows and web server metrics from IIS together, giving you the complete picture. For .NET applications, this provides the web tier visibility that complements your application performance monitoring.

And the dashboards use IIS terminology, so Windows administrators feel right at home.
