Investigating additional managed server, partition, and VIOS details

If you see any indicators that can potentially lead to performance degradation, you can explore managed servers, partitions, and virtual I/O servers in more detail to find out more information that can help you prevent service interruptions. To do that, select a desired managed server, partition, or virtual I/O server object, and click Explore in the top-right corner of the Selected Service PowerVM view.

The type and extent of information appearing in the resulting Details view depends on the type of the selected object. For example, if you drill down on a PowerVM partition, the Details view consists of four tabs: Overview, CPU, Memory, Storage, and Network, each describing the relevant resource-related details.

Observe the information on these tabs when you want to understand the underlying cause of performance degradation. For example, unusually high values of memory usage can lead to system degradation and should be further investigated.

Exploring PowerVM partition and PowerVM VIOS overviews

The Overview tab appears open when you explore a PowerVM® partition or a PowerVM VIOS for the first time. It displays the state of the partition's processor, memory, disk, and network resources. These visual elements are connected with graphical flows that illustrate the flow of data in real time. For example, you can review the rates of incoming and outgoing network data.

To navigate to this tab, in the Selected Service PowerVM, select a PowerVM partition or a PowerVM VIOS, and click Explore.

The running state of the PowerVM Partition or VIOS. Possible values include: Not Activated, Starting, Running, Shutting Down, Error, Open Firmware, Not Available.

The name of the currently used PowerVM Partition or VIOS profile. A profile specifies how many processors, how much memory, and which I/O devices and slots are to be allocated to the partition. A PowerVM Partition or VIOS can have multiple profiles.

The process model of the PowerVM Partition or VIOS. There are two types of processing modes: Shared and Dedicated. Shared mode allows assigning partial processor units from the shared processor pool. Dedicated mode indicates that all processor units can be assigned to one PowerVM partition or VIOS, for its own use.

Indicates if the PowerVM Partition or VIOS can donate spare processor cycles to the shared pool.

The number of threads the PowerVM Partition or VIOS uses.

The memory model the PowerVM Partition or VIOS uses: Dedicated or Shared.

The name of the PowerVM Partition or VIOS

The ID of the PowerVM Partition or VIOS object in your monitored system.

The type of the system host on which the PowerVM Partition or VIOS object is running: Virtual or Physical.

The serial number of the PowerVM Partition or VIOS.

The OS name and version running on the PowerVM Partition or VIOS.

The default PowerVM Partition or VIOS profile, indicating how resources are assigned to that component (selected or all resources). If the current profile does not exist, the system loads this default profile. A profile specifies how many processors, how much memory, and which I/O devices and slots are to be allocated to the partition. A PowerVM Partition or VIOS can have multiple profiles.

NOTE: For information about the other views also appearing in PowerVM Partition Details view, see the Foglight User Guide.

Exploring managed server profiles

The Server Profile tab appearing on the managed server view displays system configuration information about the selected managed server. Use it to find out the overall capacity of the physical system hosting multiple logical partitions.

To navigate to this tab, in the Selected Service PowerVM view, select a managed server, and click Explore.

The amount of system memory allocated to this managed server.

The portion of system memory that can be allocated to the shared memory pool and reallocated to PowerVM partitions associated with the managed server.

The portion of system memory that cannot be allocated to the shared memory pool.

Investigating the use of PowerVM partition and VIOS processor resources

The CPU tab of the Partition detail view or VIOS detail view shows the amount of processor resources dedicated to the selected object and their entitlement mode. It also shows the top processor consumers on the host, the top processes’ utilization trends, and illustrates the processor load.

To navigate to this tab, in the Selected Service PowerVM view, select a PowerVM® partition or a VIOS, click Explore, and in the view that appears, open the CPU tab.
