Maximizing Dashboard Functionality in Multi-Adapter Environments

by bluemedora_editor on June 11, 2015

The dashboards in Blue Medora’s vRealize Operations Management Pack for NetApp Storage are one of the product’s most useful features. With 14 out-of-the-box dashboards, administrators can easily choose and configure views that fit their respective areas of interest. In environments with multiple adapters, however, dashboards can quickly become a source of confusion.

Environments with multiple adapters, or mixed environments, most commonly occur in companies implementing new NetApp Cluster-Mode technology. During implementation, production is maintained using previously established NetApp 7-Mode Storage Systems. To support this mixed environment, companies must run adapters for both 7-Mode and Cluster-Mode on their Management Pack for NetApp Storage. Both systems will feed the dashboards without any real distinction between the two.

We will clear up the confusion this may cause by showing administrators how to choose which adapter is displayed on each dashboard. The Management Pack for NetApp Storage contains both dashboards with independent widgets and dashboards with interactive widgets. From an administrative standpoint, this means some dashboards will be changed by editing each widget individually while others will be changed simply by editing the parent widget. Both processes will be covered in this blog post.

Selecting the Adapter – Dashboards with Independent Widgets

When using independent widgets, applying a change to one widget does not affect other widgets on the dashboard. Using a single adapter across the dashboard requires separate edits for each widget.

Dashboards with independent widgets include:
•NetApp Overview
•NetApp Top-N Systems
•NetApp Top-N LUNs
•NetApp Top-N Disks
•NetApp Top-N Volumes
•NetApp Top-N Storage Virtual Machines
•NetApp Historical Debugging

 

When the dialog box appears, navigate to the Filters available for the widget. Expand Adapter Instances, then expand the NetApp Adapter Instance. At this point, you can choose which adapter is feeding your dashboard. Take note that it is possible to select a different adapter for each widget. If you are trying to make an entire independent dashboard display data from the same adapter, be sure to select that adapter for each widget. In our case, we will select either netapp-api, or netapp-dfm.

Selecting the Adapter – Dashboards with Interactive Widgets

Dashboards with interactive widgets are built so that a root parent widget drives all child widgets. In this setup, editing the adapter instance of the parent synchronizes the information of the child widgets.

Dashboards with interactive widgets include:
•NetApp Systems
•NetApp SVM QoS
•NetApp System Explorer*
•NetApp IOPS
•NetApp Virtual Machine Troubleshooting

Be aware that while it is still possible to edit the adapter instance of a child widget, it is not recommended. Because the child widget automatically receives data from the parent, it will be limited to data from the same adapter as the parent. If the adapter of a child is changed to something other than that of the parent, it will cause all data to disappear from the child widget.

Editing the adapter instance of this widget will cause Select a System, Metrics, Top Alerts, NetApp System Information, NetApp System Capacity, and NetApp System Operations and Throughput to populate with data from the adapter chosen on Select a Cluster.

*Note: For the NetApp System Explorer dashboard, editing the adapter instance requires you to also select the object type. To do this, first follow the steps for selecting a NetApp adapter instance. Next, expand Object Types and select NetApp Systems. Upon doing this, your systems should appear directly to the right. Simply select your systems and see that they appear in Selected Objects below.

Other Dashboards

In addition to dashboards with independent and interactive widgets, there are two dashboards on which the adapter should not be changed.

These dashboards include:
•NetApp Datastores
•NetApp Storage Topology

While it is possible to change the adapter instance on each of these dashboards, it is not recommended. Because the data on these dashboards is not collected from NetApp adapters, selecting a NetApp adapter instance causes the objects on the dashboard to disappear. If a NetApp adapter instance has been selected, edit the widget on which the objects have disappeared and deselect any NetApp adapter instances.

Getting the Most Out of Your Dashboards

Editing dashboards to display only certain adapter instances is a great way to expand the functionality of your Blue Medora vRealize Operations Management Pack for NetApp Storage.
