LeanSentry features

  • External low-overhead monitoring. Collects data from IIS logs, performance counters, WMI and ETW without agents or profilers.
  • Automatic issue detection. Detects hangs, high CPU, memory leaks, crashes and provides code-level root cause.
  • Full-stack error tracking. Shows errors across IIS, ASP.NET, HTTP.SYS and application exceptions.
  • Performance analysis. Analyzes threading, lock contention, queueing and GC to suggest optimizations.
  • On-premise deployment. Option to host LeanSentry inside a locked-down environment with no outbound traffic.
  • Alerting & reporting. Sends notifications for slow pages, errors, low memory, high CPU and provides detailed diagnostics.
