Microsoft IIS integration

The IIS integration provides web server monitoring for Microsoft IIS, including application pool health. Worker process failures are a key warning sign, since a failing pool takes its apps down with it.


What it’s for	Monitoring web traffic, requests, connections, and application pools
Under the hood	Uses Windows performance counters (the windows_exporter IIS collector)

Metrics collected

The integration collects web traffic and application pool metrics:

Requests: Rate, worker requests
Connections: Current, total
App pools: Worker process count, failures, threads
Bytes: Sent, received, total

What to know

This integration offers:

Prebuilt dashboards: IIS overview, applications, logs
Prebuilt alerts: 5xx errors, worker process failures, thread pool utilization
Pairs well with the Windows integration

Path completed

If you run web apps on Windows, IIS is likely your web server, and this integration collects its metrics through Windows performance counters for authoritative data.

You get request rates and connections, plus application pool monitoring. IIS isolates apps in pools, so you get worker process health per pool. Worker process failures are a key warning sign, since a failing pool takes its apps down with it.

It pairs well with the Windows integration, adding host metrics to web server metrics for the complete picture, and the dashboards use IIS terminology Windows admins already know.
