Network performance metrics

Performance metrics help network professionals within the industry to determine whether their network is operating as expected or the delivery of network resources is affected. Network professionals use various tools and processes to collect data about the network. This data is then used for analysis and to generate reports that indicate the actual performance of the network. These statistics are recorded and commonly used to compare the current performance with past results; this comparison helps a network professional determine whether the current performance of the network is within the expected operating state or abnormal.

The following are some common performance metrics that are used to determine whether a networking device is operating as expected or whether there’s a potential issue:

  • Temperature
  • Central processing unit (CPU) utilization
  • Memory utilization
  • Bandwidth
  • Latency
  • Jitter

Networking devices are...
