DebugView vs FastNetMon

DebugView is a debugging utility for Windows that displays debug output, system errors, and warnings sent from running processes. It allows developers to monitor debug strings, exceptions, asserts, and other debugging data in real time.

FastNetMon is an open-source network monitoring tool that analyzes traffic patterns to detect network outages, DDoS attacks, suspicious access to critical systems, and other issues. It works by analyzing netflow, sflow, and mirroring ports on switches.
