Investigating object dependencies

Dependency views visualize the relationships between the selected memory, disk, and network elements and other objects in your integrated environment, through an interactive map. Use these view to better understand resource-related dependencies, to predict the impact a potential outage may have on your environment, and to prevent such events, by reallocating resources where they are most needed.

To navigate to dependency views, in the Selected Service PowerVM view, select a PowerVM® partition, managed server, or PowerVM VIOS, and click Explore. Open the Memory tab (managed servers only), Storage tab, or Network tab, and then open the Dependencies tab.

Figure 37. Dependency tab

A typical PowerVM environment consists of many interrelated components. Understanding the dependencies between logical and virtual components in your monitored environment and the levels of resources they consume allows you to project possible performance bottlenecks that can affect the stability of your system. This can help you predict the impact a potential outage may have on your environment, and to prevent such events, by reallocating resources where they are most needed.

The Dependencies dashboard visualizes the relationships between the objects in your environment through an interactive map. The map illustrates how different components relate to each other, and the levels of the available resources available to them.

To access a Dependency map:

On the Infrastructure Environment dashboard, on the Monitoring tab, select a managed server, partition, or VIOS, and click Explore.

On the Detail view appearing in the display area, open the Storage or Network tab, and click Dependency.

Figure 38. Accessing a dependency map

A Dependency map appears in the display area.

Navigating dependency maps

The complexity of the information appearing in a dependency map depends on the selected object and the dependencies that object has with other objects within your integrated infrastructure.

In a large multi-component environment, dependency maps are likely complex and may not fit your screen. The NAVIGATOR in the top-right corner allows you to easily set the zoom level by dragging the slider into a desired position.

Figure 40. NAVIGATOR

In a dependency map, some objects are represented with container tiles, others with single-object tiles or just icons. Every object is represented with an icon, representing its type. This allows you to quickly identify the elements of a dependency map.

Table 19. Object types appearing in dependency map
	Partition		VIOS
	Host		Host’s disk
	Disk pool		Physical disk
	Network adapter		SCSI adapter
	VLAN

Every object appearing in the map includes an indicator of its health.

Figure 41. Health indicator

Dependencies between the objects in a map are illustrated with single-directional arrows.

Figure 42. Object dependencies

To find out more about an object appearing in the dependency map, click the object icon. A dwell appears, displaying more details about that object. The type and range of information appearing in the dialog box depends on the selected object’s type. For example, drilling down on a SCSI Adapter shows the counts of alarms generated against the selected adapter in each severity state, the adapter's state and description, and displays information about the data traffic processed by the adapter.

Figure 43. SCSI Adapter drilldown

However, if you drill down on a host object the resulting dialog box displays the counts of alarms generated against the selected host in each severity state, and the levels of processor, memory, network, and datastore resources the currently host uses.

Figure 44. Host object drilldown

Certain object types allows you to trace down the dependencies an object has with multiple map elements. Use this feature if you want to find out which elements are associated with a particular object whose performance you want to investigate. To do that, click the object on the map, and in the dwell that appears, click Highlight dependency.

Figure 45. Highlighting dependencies

This causes all of the related objects and dependencies to appear highlighted in the map.

Figure 46. Highlighted dependencies

In addition to Highlight dependency, some object types offer other options when selected. For example, when you click a partition, you can click Check partition details to drill down on the partition, or Expand partition or Collapse partition for contained adapters to show or hide the network adapters the selected partition uses.

Figure 47. Check partition details and Expand partition links

When you drill down on a managed server or a VIOS, their dependency maps allow you to filter the map by a partition. Doing so allows you to display only those elements associated with one or more desired partitions. This can help you to isolate specific objects in your integrated environment, and to quickly focus your attention on possible bottlenecks.
