Foglight for Infrastructure 5.9.2

A PowerVM® Virtual I/O Server (VIOS) enables logical partitions to share physical resources of a managed server among multiple PowerVM partitions. It can provide virtualized storage along with network adapters, allowing you to facilitate the LAN and disk resources. You can monitor the performance of VIOS instances when you select the VIOS tile on the Infrastructure Environment dashboard.

The Summary - All VIOS view identifies five servers with the highest processor and memory utilization, and the most or least available storage space, and the most or least network throughput. This view appears in the Selected Service PowerVM view when you select All VIOS in the VIOS view on the left. Use it to quickly locate a VIOS with available resources that can be put to better use in your integrated environment.

Viewing individual PowerVM VIOS details

The VIOS Summary view displays the resource utilization for the selected PowerVM® VIOS. This view identifies the resource components managed by this VIOS, the levels of available and assigned disk resources, the network throughput rate and numbers of errors and dropped packets over the selected time range, and the trends in the host processor and memory utilization.

This view appears in the Selected Service PowerVM view when you select the VIOS tile, and then click a VIOS in the VIOS view on the left. Use it to review the trends in usage of the resources managed by the selected PowerVM VIOS, and to review any generated alarms, if they exist. For example, high peaks in the VIOS Managed Network Resource chart could indicate performance degradation and should be investigated.

Table 8. VIOS Summary view
Managed I/O Resources
	Physical Volumes	The number of physical disks available to the PowerVM virtual I/O server, followed by the numbers of physical disks in each severity state: Normal , Warning , Critical , and Fatal .
	Storage Pools	The number of storage pools available to the PowerVM virtual I/O server, followed by the numbers of storage pools in each severity state: Normal , Warning , Critical , and Fatal .
	Logical Volumes	The number of logical disks available to the PowerVM virtual I/O server, followed by the numbers of logical disks in each severity state: Normal , Warning , Critical , and Fatal .
	Media Repository	The number of media repositories available to the PowerVM virtual I/O server, followed by the numbers of media repositories in each severity state: Normal , Warning , Critical , and Fatal .
	Physical SCSI Adapter	The number of physical SCSI (Small Computer System Interface) adapters available to the PowerVM virtual I/O server, followed by the numbers of physical SCSI adapters in each severity state: Normal , Warning , Critical , and Fatal .
	Physical FC Adapter	The number of physical FC (fiber channel) adapters available to the PowerVM virtual I/O server, followed by the numbers of adapters in each severity state: Normal , Warning , Critical , and Fatal .
	Physical Ethernet Adapter	The number of physical Ethernet adapters available to the PowerVM virtual I/O server, followed by the numbers of adapters in each severity state: Normal , Warning , Critical , and Fatal .
VIOS Managed Storage Resource
	Entitled	The amount of disk space that is managed by the PowerVM VIOS.
	Available	The amount of disk space that is managed by the PowerVM VIOS, and is available for entitlement to the associated PowerVM partitions, or for its own use.
VIOS Managed Network Resource
	Throughput	The rate at which the PowerVM VIOS transfers data to and from the network during the selected time range.
	Errors	The rate at which the PowerVM VIOS encounters errors while transferring data to and from the network during the selected time range.
	Packets Dropped	The rate at which the PowerVM VIOS drops data packets while transferring data to and from the network during the selected time range. By default, network adapters send or receive multiple data packets in a single request. When data packets are dropped before reaching their destinations, this may indicate a problem with the network connection or the network adapters.
Host Running Status
	CPU Utilization	The percentage of the allocated processor resources that the host associated with the PowerVM VIOS currently uses.
	Memory Utilization	The percentage of the allocated memory resources that the host associated with the PowerVM VIOS currently uses.

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.

Figure 25. Exploring monitored PowerVM objects in more detail

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.

Figure 26. PowerVM Partition Details view

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.

Table 9. PowerVM Partition Details and PowerVM VIOS Details views
Partition/VIOS Current Status
	State		The running state of the PowerVM Partition or VIOS. Possible values include: Not Activated, Starting, Running, Shutting Down, Error, Open Firmware, Not Available.
	Current Profile		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.
	CPU
		Process Model	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.
		Enable Donate	Indicates if the PowerVM Partition or VIOS can donate spare processor cycles to the shared pool.
		Smt	The number of threads the PowerVM Partition or VIOS uses.
	Memory
		Memory Model	The memory model the PowerVM Partition or VIOS uses: Dedicated or Shared.
Partition/VIOS Basic Profile
	Partition/VIOS Name		The name of the PowerVM Partition or VIOS
	Partition ID		The ID of the PowerVM Partition or VIOS object in your monitored system.
	Host Type		The type of the system host on which the PowerVM Partition or VIOS object is running: Virtual or Physical.
	Logical Serial Number		The serial number of the PowerVM Partition or VIOS.
	OS Version		The OS name and version running on the PowerVM Partition or VIOS.
	Default Profile		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.
