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.
NOTE:
Monitoring capacity metrics is enabled when an appliance is in Out Of Space (OOS) mode. This way it is possible to
monitor the amount of space freed as a result of deleting unused snapshots and storage resources.
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 refresh interval is set according to the selected granularity level as follows:
