Catch, diagnose, and fix with expert guidance ... without doing any of the hard work.
externalnon-blockingRuns side-by-side with your APM
Low overhead monitoring, that can run side-by-side with your existing APM tools.
APM tools use profilers that intercept your application's execution. This can destabilize and slow down your apps.
LeanSentry uses external, non-intrusive monitoring that combines data from standard Windows logs including IIS logs, ETW traces, performance counters, and so on. This has almost zero overhead on your server and cannot crash or slow down your applications.
Our customers say
In the first 3 weeks of use, we resolved 3 production issues affecting performance and availability. LeanSentry is now our go to tool for insight into how our applications are running.
Platform Architect, OrderDynamics
Great product & company to work with. Ex MS guys who know IIS and the MS stack. You work with the team directly, not a customer care layer. LeanSentry uncovers things in minutes vs. days of digging.
Operations Manager, Pacific DataVision
I have not seen a service that provides so much information with so little setup. LeanSentry made it simple to diagnose errors and slowdowns, and gave us a way to measure our success in resolving application issues.
Web Developer, InfoTrack
We were seeing severe hangs on our ASP.NET site.
Looked at what LeanSentry said was the cause of the hang,
disabled that code, and it’s been smooth sailing since.
