#network-monitoring

Linux has a tool for everything. Sometimes those tools come in the form of an easy-to-use GUI, and other times a command is necessary. For monitoring network traffic, your best bet is the command line. Once you dive down the rabbit hole of possible commands for this task, you could become overwhelmed with choices -- and with the complexity of some of those commands.

For any IT department, these four words are the beginning of a familiar, often frustrating, journey. In our modern world, where business success is built on distributed applications and hybrid cloud architectures, the network is the circulatory system. When it fails, everything grinds to a halt. Yet, despite its critical importance, it often remains a black box-a source of blame that is difficult to prove or disprove.

Enhanced root cause analysis- When issues occur, having access to complete, unsampled data dramatically improves your ability to identify root causes and troubleshoot issuesquickly. Instead of extrapolating from sampled data points, your team can analyze the full context of system behavior leading up to and during incidents. Eliminating cardinality constraints- Teams can focus on analysis of key historical data to predict and prevent future occurrences rather than complex data preprocessing, multiple monitoring tiers, or custom aggregation logic.
