3 Monitoring Capacity This chapter includes: Topics: • About monitoring system capacity • Capacity data collection and retention periods • Capacity forecasting and recommendations • Capacity data locations in PowerStore Manager • Start monitoring capacity usage • Data Savings features About monitoring system capacity PowerStore provides various current usage, and historical metrics. The metrics can help you monitor the amount of space that is used by your system resources, and determine your future storage needs. Capacity data can be viewed from the PowerStore CLI, REST API, and PowerStore Manager. This document describes how to view this information from PowerStore Manager. Refer to the PowerStore Online Help for specific capacity metric definitions and calculations. Monitoring current usage capacity You can use the PowerStore Manager, REST API, or CLI to monitor the current capacity usage for a cluster, and for individual storage resources such as storage containers, volumes, file systems, and appliances. Also, with a PowerStore X model implementation, you can view the capacity usage of a virtual machine and a virtual volume. Monitoring historical usage and forecasting PowerStore capacity trending and predictive metrics are also collected for forecasting future storage needs of a cluster or appliance. Also, the trending and predictive metrics can be shared with the Dell EMC Support Center when PowerStore is configured with Support Assist. These metrics provide intelligent insight on how capacity is being used and help to predict future capacity needs. Capacity data collection and retention periods Collection of capacity metrics is always enabled. Current capacity data collection and retention periods Capacity data for system resources is collected at 5 minute intervals and rolled up to 1 hour and 1-day aggregates. The capacity charts are automatically refreshed each time a new data collection becomes available. The following table displays the retention periods for each timescale and the resources to which they apply: Table 1.
