nChronos vs Observer GigaStor

nChronos is Colasoft’s application-focused network performance analysis system for medium and large corporate networks. Its client/server design places continuous packet capture, analysis, storage and data mining on a server, while a console displays and analyzes the collected data. The server can receive traffic through a network mirror port or link tap and retain packets for later investigation of network or application problems. Real-time statistics and user-defined alerts show network events as they occur. System or custom reports can be scheduled for hourly, daily, weekly or monthly email delivery. Users can define application and transaction monitoring, with profiles for HTTP, FTP, email and DNS. Packet files can be replayed from Colasoft, libpcap and several vendor formats, including files associated with Wireshark, Ethereal and Tcpdump. Linux server systems and Windows consoles are listed, with browser-based server configuration. Standard specifications allow four logical links, eight capture interfaces and two concurrent server connections.
