System Analysis Reports
If a system is configured with sufficient CPU, memory, bandwidth, and disk resources, the applications executing on it seldom suffer performance degradations. Therefore, when planning the capacity of their mission-critical applications/business services, administrators need to historically analyze how the systems hosting these applications/supporting these business services used the physical resources that were at their disposal, identify usage bottlenecks, and if required, recommend changes in system size as part of their capacity plans, so that unpleasant application crashes or service outages can be averted in the future. Such a detailed appraisal of system-level resource usage can be performed using the Systems Analysis Reports.
For each critical system resource that is monitored (CPU, memory, disk space, disk activity, and bandwidth), this report computes and displays how that resource was utilized on an average (Avg) during a given timeline and also computes the 95th percentile value of the corresponding usage measure. In addition, by comparing the 95 percentile value with user-configured thresholds for the same, the report promptly detects and highlights resource usage bottlenecks and the severity of these bottlenecks.
This report can be generated for a particular Component, for the components engaged in the delivery of a Service, or for the components that are part of a Segment and Zone.
