The above metrics are just examples of what can be considered in DSA cloud services meteorology. The design can create categories of metrics. For example, the design can consider QoS category metrics to include packet delay, loss, and jitter. The design can consider security category metrics to include exposing a node to an eavesdropper or exposing a network to a jammer, the metric could measure the time of exposure to these security risks. The design can also consider the need for human intervention. A network administrator monitoring the use of DSA resources may intervene in cases of complete failure of the system to recover autonomously. The number of incidents that require human intervention can be turned into a metric. Some IaaS references name this metric the automatization degree.
