SCOM/AviCode. System Center Operations Manager is a comprehensive and complex platform for monitoring Windows Server, and provides code-level analysis with the AviCode profiler. LeanSentry complements SCOM well by providing a very simple view of application performance that is much easier to use. LeanSentry also automatically diagnoses IIS/ASP.NET production problems like hangs and crashes, whereas SCOM does not.
New Relic/AppDynamics. Both of these are good multi-platform production profilers that provide code-level analysis. LeanSentry is made specifically for Windows Server applications. LeanSentry does not use a profiler, and as a result does not always provide the same code-level details. However, LeanSentry is significantly more lightweight because it does not load a profiler into your applications. Additionally, LeanSentry automatically diagnoses production IIS/ASP.NET problems like hangs and crashes, whereas those tools do not.
Nagios/ServerDensity/etc. LeanSentry is made to provide deeper Windows Server monitoring and diagnostics than the traditional server monitoring tools. Instead of just showing you the performance data, LeanSentry creates a simple to understand picture of your application. Additionally, LeanSentry automatically diagnoses production IIS/ASP.NET problems like hangs and crashes, whereas those tools do not.
EventViewer/Performance Monitor/LogParser/etc. These traditional diagnostic tools have been the bread and butter of production troubleshooting for years. Unfortunately, these tools do not provide 24x7 production monitoring, do not aggregate data, and require platform expertise to make sense of the data. LeanSentry takes things to the next level by analyzing the data for you, and giving operations a simple but effective view of application health. Additionally, LeanSentry automatically diagnoses production IIS/ASP.NET problems like hangs and crashes, whereas those tools do not.
Debuggers/Profilers/AdPlus/DebugDiag. These tools have been developer favorites when troubleshooting production problems. Using these tools in production is hard because it relies on catching the problem live. These tools have a very high overhead that prevents them from running in production 24x7. LeanSentry replaces these tools with lightweight 24x7 monitoring that always detects problems, and automatically diagnoses most problems without the need for manual profiling or debugging.
