1 Introduction to Power Manager Dell EMC OpenManage Enterprise Power Manager is a plugin to the Dell EMC OpenManage Enterprise (OME) console and uses fine-grained instrumentation to provide increased visibility to power consumption, system anomalies, and resource utilization on Dell EMC servers. Also, Power Manager supports virtual machine monitoring, and alerts and reports about power and thermal events in servers, chassis, and custom groups consisting of servers and chassis.
2 Revision history Table 1. Revision history of document Date Document version Description of changes June 2021 A00 Initial release of the document. August 2021 A01 ● Updated compatible version of OpenManage Enterprise. ● Removed the iDRAC version limitation.
3 What is new in this release ● Support for monitoring Power Distribution Unit (PDU) devices. ● Support for monitoring Virtual Machines (VM) that are hosted on hypervisors that have been discovered in OpenManage Enterprise and added to Power Manager. ● Power Manager: Virtual Machine Performance Report integrated to view VM details monitored in Power Manager. ● Support for monitoring 8000 devices that include servers, PDUs, virtual machines, and 500 groups (static and physical).
4 Compatibility matrix Topics: • • • • Supported devices in Power Manager Supported protocols Versions of Power Manager compatible with OpenManage Enterprise Role and scope-based access control in OpenManage Enterprise Supported devices in Power Manager Power Manager supports the following list of Dell EMC PowerEdge servers and chassis. Table 2.

Table 5. Role-based user privileges for Power Manager (continued) Features Administrator Device Manager (scope for assigned groups) Device Manager (scope for non-assigned groups) Viewer Add or remove Power Distribution Units (PDUs) from Power Manager. Yes Yes No No Monitor PDUs. Yes Yes No Yes Create, edit, or delete Physical Groups. Yes No No No Import physical groups Yes through CSV file No No No Manage the devices in Yes rack. No No No Monitor metrics.
Scope-Based Access Control (SBAC) in OpenManage Enterprise With the use of Role-Based Access Control (RBAC) feature, administrators can assign roles while creating users. Roles determine their level of access to the appliance settings and device management features. Scope-based Access Control (SBAC) is an extension of the RBAC feature that allows an administrator to restrict a Device Manager role to a subset of device groups called scope.
NOTE: Post upgrade of OpenManage Enterprise from versions 3.5 or earlier, the AD/LDAP and OIDC (PingFederate or KeyCloak) device managers would need to recreate all the previous-version entities as these entities are only available to the administrators post upgrade. For more information, see the Release Notes at https://www.dell.com/support/home/ en-yu/product-support/product/dell-openmanage-enterprise/docs. SBAC for OIDC users: Scope assignment for OIDC users does not happen within the OME console.
5 License requirements Use OpenManage Enterprise Advanced license together with your iDRAC license to work with all the features of Power Manager. The following table provides the license combinations that is required to add and monitor servers in Power Manager. Table 6.
● If EPR is enabled on a group, and if the license is expired or deleted for any device in a group, the device is not removed from Power Manager. ● If EPR is enabled on a group, you cannot remove the group or any device that is part of the group from Power Manager.
6 Scalability and performance Power Manager supports up to 8,000 target devices that include 500 groups—static and physical groups, servers, virtual machines, and Power Distribution Units (PDUs). Configure appropriate power and temperature sampling intervals in Power Manager. The sampling intervals impact the system performance and footprint significantly, including network bandwidth consumption, database size, and trend graph display latency.

17 Frequently Asked Questions Why am I not able to view the metrics? Cause: After removing the required iDRAC or DC License, or the OpenManage Enterprise Advanced Feature license, the license-dependent features are not available on the User Interface (UI). Therefore, the metric is not available, and the values are not collected by Power Manager from the next inventory cycle.
Why do I not see all metric types for different types of devices? Cause: Different devices support different types of metrics. Table 21.
Why do I see a failure of EPR in audit log but EPR is applied successfully for the group? Cause: When EPR option is applied for a group, and if the EPR option is applied successfully for at least one device in the group, the EPR banner is displayed at the group level. However, the EPR option may fail on other devices within the group due to connectivity issues or license expiry and so on. Therefore, use the EPR audit logs for successful and failure scenarios for all devices of the group.
Why is Power Manager not listed on Console and plugins page? Cause: Power Manager may not be listed due to the following reasons: ● The offline share folder is not accessible. ● Power Manager plugin and tar folder.s are not present in the offline share folder. ● If the plugin catalog file is edited, then the signature files can get corrupted. Resolution: Ensure that the offline share folder is reachable through OpenManage Enterprise with the following files: ● ome_powermanager_1.0.0.tar.
Why do I not see temperature metric for some devices? Cause: The temperature metric is not visible for devices if they are powered off. Why can I not select a particular child group? Cause: When you select a group, all the child groups within this group are also selected. Likewise, when you clear a child group the selection gets cleared at the main group level.
Why can I not clear the checkbox for policies? Cause: The checkbox for policies in the Power Policies page is disabled if that policy is being enabled, disabled, or edited. After the job is completed, you can clear the policy. How do I see the old metric data? Cause: The old metric data is not available after a few days because the data is deleted. This configuration depends on the selection of the Delete Power Manager data option available in the Power Manager Preferences section.
18 Troubleshooting Data purge interval not reset Scenario: After reinstalling or updating to the latest version of Power Manager, the data purge interval is not reset to the default value.
Why is OpenManage Enterprise unresponsive when I try to perform plugin lifecycle-related actions (install/uninstall/ enable/disable)? Scenario: After rebooting OpenManage Enterprise appliance, if you try to perform any plugin lifecycle-related actions for Power Manager, the job is initiated in the back-end but you still see the Console and Plugins page. And, the following message is displayed after some time: This page isn't working Resolution: Wait for some time, and view the status.
When devices are simultaneously added to and removed from a static group through OpenManage Enterprise, there are multiple entries of this update in the Audit Logs and Alert Log. All options for managing physical groups are not displayed Scenario: After creating a physical group, you may not see Create New Physical Group, Edit Group, Manage Rack, Delete Group, or Attributes options when you right-click any group.
