Gauge charts

The data of CPU, memory, network, and disk usage are represented using a spinner (also known as rotating wheel) which is divided into four severity levels, including Normal (in green), Warning (in yellow), Critical (in orange), and Fatal (in red).

Figure 11. Rotating wheels shown in monitored server/VM views

CPU load spinner

The severity of CPU Load is calculated based on the following formula: (utilization current average - utilization period average)/utilization period standardDeviation. If this value is:

•
Larger than 4: the CPU load spinner will be show in red, which indicates its severity level is Fatal.
•
Larger than 3 but less than/equal to 4: the CPU load spinner will be shown in orange, which indicates its severity level is Critical.
•
Larger than 2 but less than/equal to 3: the CPU load spinner will be shown in yellow, which indicates its severity level is Warning.
•
Less than or equal to 2: the CPU load spinner will be shown in green, which indicates its severity level is Normal.
Network I/O spinner

The severity of Network I/O is calculated based on the following formula: (transferRate current average - transferRate period average)/transferRate period standardDeviation. If this value is:

•
Larger than 4: the Network I/O spinner will be show in red, which indicates its severity level is Fatal.
•
Larger than 3 but less than/equal to 4: the Network I/O spinner will be shown in orange, which indicates its severity level is Critical.
•
Larger than 2 but less than/equal to 3: the Network I/O spinner will be shown in yellow, which indicates its severity level is Warning.
•
Less than or equal to 2: the Network I/O spinner will be shown in green, which indicates its severity level is Normal.
Memory Load spinner

The severity of Memory Load is calculated based on the following formula: (currentPressure current average - currentPressure period average)/currentPressure period standardDeviation. If this value is:

•
Larger than 4: the Memory load spinner will be show in red, which indicates its severity level is Fatal.
•
Larger than 3 but less than/equal to 4: the Memory load spinner will be shown in orange, which indicates its severity level is Critical.
•
Larger than 2 but less than/equal to 3: the Memory load spinner will be shown in yellow, which indicates its severity level is Warning.
•
Less than or equal to 2: the Memory load spinner will be shown in green, which indicates its severity level is Normal.
Disk I/O spinner

The severity of Disk usage is calculated based on the following formula: (diskTransferRate current average - diskTransferRate period average)/diskTransferRate period standardDeviation. If this value is:

•
Larger than 4: the Disk usage spinner will be show in red, which indicates its severity level is Fatal.
•
Larger than 3 but less than/equal to 4: the Disk usage spinner will be shown in orange, which indicates its severity level is Critical.
•
Larger than 2 but less than/equal to 3: the Disk usage spinner will be shown in yellow, which indicates its severity level is Warning.
•
Less than or equal to 2: the Disk usage spinner will be shown in green, which indicates its severity level is Normal.

Virtual Environment view

This view appears in the upper part of the Monitoring tab, just above the Quick-View. It displays a high-level overview of the selected virtual environment. The view has a tile for each type of object in your virtual infrastructure: Clusters, Servers, SCVMM Servers, SOFS Servers, Virtual Machines, Storage, and Virtual Switches.

Figure 12. Virtual Environment view

Each tile shows how many of the corresponding object instances there are in your virtual infrastructure, as well as the count of objects of that type in each of the alarm states (Normal, Warning, Critical, Fatal). For example, the following image shows four physical servers: none in the Fatal, Critical or Warning states, and four in the Normal state.

Figure 13. Configuring tiles in the Virtual Environment view

You can move the tiles by dragging and dropping until you achieve the desired layout.

To hide one or more tiles:
1
On the tool bar on the right, click Edit .
2
In the dwell that appears, click a tile that you want to hide and click Apply.
The selected tile is hidden in the Virtual Environment view.

Clicking the object type icon, the object type name, or the object count, shows summary information for that object type in the Quick-View. Clicking an alarm state (for example, Warning) on a tile displays summary information in the Quick-View for the objects of that type that are in the selected alarm state. If an alarm state has a count of zero, then you cannot drill down on the alarm state.
