Tune and troubleshoot your IIS applications like an expert

Dive Deep

Single dashboard shows you the overall application health, and lets you zoom into all the important details: every URL, error, server, slow request, and more.

Aggregate data across multiple servers, URLs, and apps gives you a complete picture of your application.

Never miss anything with a 24x7 historical record with up to 10s resolution: look at the entire month or zoom into seconds to see exactly what happened.

All the metrics in one place, linked to each other in the way you could never get with Event Log, PerfMon, Log files, and traces.

Become the expert with expert analysis that helps you make sense of your data.
