Preface As part of an improvement effort, revisions of the software and hardware are periodically released. Some functions that are described in this document are not supported by all versions of the software or hardware currently in use. The product release notes provide the most up-to-date information about product features. Contact your service provider if a product does not function properly or does not function as described in this document.
1 Monitoring Your System Overview This chapter includes: Topics: • Overview Overview This document describes the functionality available in the PowerStore Manager to monitor, and optimize various PowerStore appliances. Monitoring features PowerStore Manager provides the following features and functionality to monitor your system: ● ● ● ● Events to notify when there are changes in the system. Alerts to inform you that an event occurred that requires your attention.
2 Managing Alerts This chapter includes: Topics: • • • • • • • • Events and alerts Monitor alerts Configure email notification preferences Temporarily disable alert notifications Configure SNMP Critical Information Banner System Checks Remote logging Events and alerts Events provide information about changes to the system. Alerts are events that require attention. Most alerts indicate that there is a problem with the system. The system displays ongoing alerts in the dashboard on the Alerts card.
Table 2. Additional alert attributes Attribute Applies to Explanation Error Code Alerts Error code associated with the alert. Use this code to find troubleshooting information. Respond Alerts Mark an alert acknowledged or unacknowledged. Acknowledged alerts are not displayed by default. Repair Flow Alerts Recommended steps to resolve the situation. Some actions can be performed directly from the alert window. Notifications Alerts Whether the alert triggered an email notification.
Configure email notification preferences You can configure your system to send alert notifications through email using an SMTP server. About this task Use this procedure to configure an SMTP server and email recipients. Steps 1. Select the Settings icon, and then select SMTP Server in the Networking section. 2. To access the SMTP server settings, change the status to Enabled. 3. Add the SMTP server address and the email address that notifications should be sent from and click Apply.
2. To add an SNMP Manager, click Add under SNMP Managers. The Add SNMP Manager slide out appears. 3. Depending on the version of SNMP, configure the following information for the SNMP Manager: ● For SNMPv2c: ○ Network Name or IP address ○ Port ○ Minimal Severity Level of Alerts ○ Version ○ Trap Community String ● For SNMPv3 ○ Network Name or IP address ○ Port ○ Minimal Severity Level of Alerts ○ Version ○ Security Level NOTE: Depending on the security level selected, additional fields appear.
System Checks The System Checks page enables you to initiate health checks on the overall system, independent of the system-issued alerts. About this task You can launch a system check prior to actions such as upgrade, to be able to intercept and resolve any issues prior to upgrading the system. The System Check table displays the following information: Table 3.
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.
Table 4. Capacity charts refresh intervals Granularity Level Refresh Interval Last 24 hours 5 minutes Last month 1 hour Last 2 years 1 day The following table displays the retention periods for each timescale and the resources to which they apply: Table 5.
Figure 1. Cluster capacity chart - forecasting 1. Selecting the Forcast option, you can see the mean predicted physical usage (for the next 7days). 2. Selecting the Forcast Range option, you can see the range of low-to-high predicted physical usage (for the next 7days). 3. Hovering the mouse over the forecast section of the capacity chart, you can see the values for mean predicted usage and range of predicted usage. Capacity recommendations PowerStore also provides a recommended repair flow.

● Data reduction, which consists of deduplication and compression. ● Thin provisioning, which enables multiple storage resources to subscribe to a common storage capacity. The drive usage that is saved by these data services results in cost savings and consistent, predictable high performance, regardless of workload.
to actual storage usage. While the system allocates only a portion of the physical capacity requested by each storage resource, it leaves the remaining storage available for other storage resources to use. The system reports the capacity savings gained from thin provisioning using the Thin Savings metric, which is calculated for volume families and file systems. A volume family consists of a volume and its associated thin clones and snapshots. Thin provisioning is always enabled.
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.
Refer to the PowerStore Online Help for specific performance metric definitions and calculations. Table 10. Performance data locations For Access path Cluster Dashboard > Performance Virtual Machine ● Compute > Virtual Machine > [virtual machine] opens with the Compute Performance card that is displayed for the virtual machine. ● Compute > Virtual Machine > [virtual machine] > Storage Performance NOTE: Only available with PowerStore X model appliances.
2. Select the volumes on which you are changing the policy. NOTE: You can only set the same policy on the selected volumes. 3. Select More Actions > Change Performance Policy. 4. Select a performance policy, and select Apply. Working with performance charts You can work with the performance charts to customize the display. Print performance charts, or export the performance data to display in an alternative application.
