All performance indicators in one place!

LeanSentry v2 is here, Gangnam style!

LeanSentry v2 is finally here, bringing you 10x the diagnostic power to monitor and troubleshoot your IIS/ASP.NET web apps!

If you don’t already know, LeanSentry is a production monitoring service made specifically for IIS/ASP.NET apps, to make these really painful things easy as pie:

1) Catching and troubleshooting IIS and ASP.NET errors
2) Solving performance problems and finding the cause of slow requests
3) Sizing up server utilization and resource usage problems

These things constantly drain hours of time when running production apps. LeanSentry uses extremely lightweight monitoring to provide the kind of monitoring insights typically available only with serious tools like logparser, debuggers, and profilers. Unlike those tools, LeanSentry is designed specifically to show you the key things an IIS expert will want to see, and hide the rest of the noise. And, its designed to do it with 24/7 continuous production monitoring that does not impact your application performance.
