High network utilization occurs when the volume of data on a network link approaches the capacity of the link. Netdata agent calculates the average outbound utilization for a specific network interface over the last minute. High outbound utilization increases latency and packet loss because packet bursts are buffered. - -This alarm may indicate either a network congestion or malicious activity. - -### Troubleshoot the alert - -- Prioritize important traffic - -Quality of service (QoS) is the use of mechanisms or technologies to control traffic and ensure the performance of critical applications. QoS works best when low-priority traffic exists that can be dropped when congestion occurs. The higher-priority traffic must fit within the bandwidth limitations of the link or path. - -- Add more bandwidth - - - For **Cloud infrastructures**, adding bandwidth might be easy. It depends on your cloud infrastracture and your cloud provider. Some of them either offer you the service to upgrade machines to a higher bandwidth rate or upgrade you machine to a more powerful one with higher bandwidth rate. - - - For **Bare-metal** machines, you will need either a hardware upgrade or the addition of a network card using link aggregation to combine multiple network connections in parallel (e.g LACP). - -### Useful resources - -- [FireQOS](https://firehol.org/tutorial/fireqos-new-user/) is a traffic shaping helper. It has a very simple shell scripting language to express traffic shaping. - -- [`tcconfig`](https://tcconfig.readthedocs.io/en/latest/index.html) is a command wrapper that makes it easy to set up traffic control of network bandwidth/latency/packet-loss/packet-corruption/etc.
