    Though this list accounts for both open-source and closed-source products, it focuses on Linux-based network monitoring tools. A handful of common tools only operate on Windows, Pandora, or other systems, but most network monitoring tools run on Linux systems since Linux—with its higher degree of user input and easily recodeable security bugs—is often the choice for IT specialists who wish to manage network systems in growing enterprises. For this reason, I’ve excluded the few non-Linux-compatible monitoring tools. My personal favorite is SolarWinds NetFlow Traffic Analyzer—read my review below to learn why.

    Scalable distributed monitoring system
    Pricing:
    • Open Source
    You’ll need to weigh scalability against other considerations. An open-source program like Ganglia is highly scalable—scalability is Ganglia’s niche—but it might not provide the easy visual interface or automatic data analysis some of the other tools can offer. A software like Ganglia, with low per-node overhead, may be useful for researchers looking to monitor the basics of large network operations. But for IT specialists monitoring a large company network, other programs might be a better fit. More comprehensive monitoring tools, like SolarWinds NTA or Nagios Network Analyzer, might be more desirable for their real-time graphical analysis and security alert systems.
