Predicting Wi-Fi performance: Can it be done?

Whenever I plan and configure an enterprise WLAN system, I always advise that an additional 10 to 20 percent of the capital budget be reserved for expansion and filling in holes in coverage or capacity that couldn't be anticipated during the planning process.

Analyze Cisco's NetFlow for free

Network traffic data holds a wealth of information about application response time, network usage and bandwidth consumption. Getting at that data in an efficient and inexpensive manner would help network managers better understand and control their networks.

Groundwork Monitor: serious network management

Best of open source in enterprise monitoring

Open source software has had a foothold in the enterprise monitoring sphere for almost as long as open source has existed. One only needs to look at the sheer ubiquity of small applications such as MRTG (Multi Router Traffic Grapher) and its RRDTool back end to see that. What we haven't had from open source is the big application -- the comprehensive, community supported open source enterprise management suite that provides the depth and breadth of functionality that businesses need and generally find in closed-source competitors. That is changing in leaps and bounds. In fact, open source enterprise monitoring solutions are evolving so quickly, we won't even try to declare a clear winner yet -- but we're working on it.
