4 Monitoring Performance This chapter includes: Topics: • About monitoring system performance • Performance data collection and retention periods • Performance data locations in PowerStore Manager • Performance policies • Working with performance charts About monitoring system performance PowerStore provides you with various metrics that can help you monitor the health of your system, anticipate problems before they occur, and reduce troubleshooting times. You can use the PowerStore Manager, REST API, or CLI to monitor the performance of a cluster, and for individual storage resources such as volumes, file systems, volume groups, appliances, and ports. Also, with a PowerStore X model implementation, you can view compute performance of a virtual machine, and the storage performance for a virtual machine, and virtual volume. You can print performance charts and download metrics data as a PNG, PDF, JPEG, or .csv file for further analysis. For example, you can graph downloaded CSV data using Microsoft Excel, and then view the data from an offline location or pass the data through a script. Performance data collection and retention periods Collection of performance data is always enabled in the PowerStore. All system performance data is collected every 20 seconds and then rolled up to 5 minute, 1 hour, and 1 day aggregates. The data is retained as follows: • 20 second data is retained for 1 hour. • 5 minute data is retained for 1 day. • 1-hour data is retained for 30 days. • 1 day data is retained for 2 years. Performance data locations in PowerStore Manager You can view performance charts for PowerStore systems, and system resources from the PowerStore Manager Performance card, views, and details as follows: Performance data is available from the PowerStore CLI, REST API, and PowerStore Manager user interface. This document describes how to access performance data and charts from PowerStore Manager. Refer to the PowerStore Online Help for specific performance metric definitions and calculations. Table 5.
