You can use the HCP S Series management API to request information about the current load on HCP S Series Node processing resources or about this load over time. The load on processing resources, called the system load, relates to the use of resources such as CPUs, network bandwidth, and memory. For each processing resource, usage statistics are available for the individual server modules and for the S Series Node as a whole. You can use system-load information to evaluate the use of these resources and to draw conclusions about the performance of the S Series Node.
