Executive summary Executive summary Use this whitepaper to monitor Power Distribution Units (PDUs) of supported brands in OpenManage Enterprise using Power Manager plugin. This also covers the inventory and alert management of PDU devices. It also covers methods for associating PDU to rack physical groups.
PDU Devices 1 PDU Devices Power Distribution Units are devices used to supply power to devices like server, storage and network equipment mounted on a datacenter rack. Smart PDUs are power distribution units which are having remote management capabilities. Power Manager 2.0 adds the ability of monitoring PDU devices from the following manufacturers on OpenManage Enterprise 3.6.1 and above. • • 1.
PDU Devices 1.2 PDU devices built-in group A new built-in group named PDU Devices is displayed under SYSTEM GROUPS on Devices page in OME. All PDU devices discovered in OpenManage Enterprise are automatically listed under PDU Devices group. PDU devices built-in group 1.3 PDU device inventory information View detailed inventory of PDU devices by navigating to the device details page of a PDU. PDU device overview Overview page shows all basic inventory details of the PDU.
PDU Devices Hardware: PDU Outlet Information PDU Outlet Information lists the number and name of outlets. PDU: Device Alerts Alerts tab lists alerts received from the PDU. 1.4 Alerts or MIB Alerts Alerts page in OME also lists alerts received from all PDU devices. The details of traps that are supported by the discovered PDUs are visible under MIB tab under Monitor page. The table lists the traps that are supported by Vertiv Geist and APC PDUs.
PDU Devices MIB You can create alert policies for associating actions such as trap forwarding or sending emails upon receipt of traps from PDU. In Create Alert Policy wizard, under Category selection step, choose the category and subcategory under desired PDU models, either APC or Vertiv Geist. Alert Policy: Category selection 1.5 9 Scale support Power Manager 2.0 supports monitoring of 8000 nodes including servers, chassis, PDUs and Virtual Machines.
PDU metrics 2 PDU metrics 2.1 Associating PDU(s) to rack In Power Manager plugin, the PDU(s) must be associated to rack physical groups to monitor rack-level power consumption. Associating a PDU to a rack automatically adds that PDU to the Power Manager monitoring list. Ensure that the PDU(s) are associated to a rack (or rack group) to monitor rack-level power consumption. Associating a PDU to a rack automatically adds that PDU to the Power Manager monitoring list.
PDU metrics 3. Select the required PDU(s) to be associated to the rack and click Next. Note: When there are many devices, use Advanced Filters to make PDU device selection easy by filtering the PDU devices. Device selection 4. Click Finish button. The Slot and Size of Device (U) are always N/A for PDU devices because, PDU devices doesn’t occupy any rack slots. Device selection 5. The PDU is associated to the rack and is shown in Associated Devices page. Associated devices 6.
PDU metrics Group membership Note: Multiple PDUs can be associated to a rack, but multiple racks cannot be associated to the same PDU. 2.2 View monitored PDU(s) This sub-section explains how to view the monitored PDU devices. 1. Launch OpenManage Enterprise, and then click Plugins > Power Management > Power Manager Devices. The Power Manager Devices tab is displayed. 2. Click All Monitored Devices tab. All the PDU Devices (along with other monitored devices) are listed on the All Monitored Devices tab.
PDU metrics 2.3 View PDU metrics To view PDU metrics for any rack physical group, go to Metrics and Monitoring history page in Group Details. View PDU Metrics Note: If you are logging in as a Device Manager, only the device groups and devices that are in your scope are available for viewing and management. For example, if you are logging in as a Device Manager DM1 user, you can view all the PDU devices that are part of the group that is assigned to a Device Manager DM1 user.
PDU metrics 2.4 Calculation of metrics for physical groups including PDU devices Following is an example of how the metrics is calculated for physical groups including PDU devices.
PDU reports 3 3.1 PDU reports This section focuses on Power Manager reports which are extended to support the PDU specific information. Device overview report Type: Built-In Description: This report contains general device information including name, type, model, identifier, and other essential fields. Advantages: The benefit of this report is that you get a consolidated report of general information of all the devices. This report is extended to support the PDU devices as well.
PDU reports NIC Report 3.3 Power and Thermal Report of Groups Type: Built-in and custom Description: This report captures power and thermal data of all groups that are monitored by Power Manager over a certain time period. The groups contain different types of devices as per your preferences.
PDU reports Note: If you are logging in as a Device Manager, only the device groups and devices that are in your scope are available for viewing and management. For example, if you are logging in as a Device Manager DM1 user, and a group G1 is assigned to the Device Manager DM1 user, you can view only those devices which are part of G1 group in these reports.
Conclusion 4 18 Conclusion Using this white paper one can easily discover PDU(s) and monitor the PDU metrics. Also, it helps you understand the benefits of these features.
