Configuring the Capacity Planning System Report Settings

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 Capacity Planning Report.

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.

To configure the thresholds that should govern the 95th percentile value of the resource usage measures, do the following:

1. To access this page, click on the icon available in the Admin tab. Then, select the Capacity Planning Report option from the Reporter sub-menu in the Settings tile.
2. Then, click on the Configure System Reports tab page therein.
3. Capacity planning system reports setting appears listing all the measures that capture system resource usage - namely, CPU utilization, Physical memory utilized, Percent disk space usage, Disk Activity - Disk busy percentage, and Bandwidth usage.
4. To begin configuring the thresholds for a measure, select a Condition. This can be > (greater than) or < (lesser than).
5. Then, specify the Major Value and/or Critical Value thresholds for the measure. In the same way, you can configure thresholds for the remaining measures. Finally, click the Update button to save the threshold settings.
6. If the > Condition is chosen for a measure, then, during report generation, the eG Enterprise will check whether the 95th percentile value of that measure is ‘greater than’ its Major Value threshold configuration or Critical Value threshold configuration. Likewise, if the < Condition is chosen, then the eG Enterprise will check whether the 95th percentile value is ‘lesser than’ the Major Value or Critical Value threshold configuration. If the Major Value threshold has been violated, then the corresponding measure value will be highlighted in Orange in the report. Similarly, a Critical Value threshold violation will result in the 95th percentile value being highlighted in Red in the report.
