The "Cluster Viewer" view allows you to represent inter-VM dependencies in the form of a graph. This shows the packets of VMs that communicate with each other. This can be useful for identifying islands within a data centre and making better placement decisions.
In addition, it is possible to filter and select resources using the options provided by the "Map data settings" panel.
In addition, by clicking on the "Flows" tab, the links between the VMs are displayed in a table, which can be exported to CSV.
Focus on certain VMs
cluster viewer allows a focus on a subset of the VMs to be set up.
To add or remove a VM from the focus, there are two possibilities:
- from the view: click on the corresponding circle after selecting
focus as an action associated with a click on a VM
- from the search tab: click on the pushpin icon to the right of the title block of a VM
The semantics of the focus are as follows:
- The resources in the focus are displayed in orange.
- Resources that are not part of the focus, but are directly linked to at least one resource in the focus, are displayed in grey.
- Links between resources are displayed as lines.
- If a link relates to at least one resource in the focus, then it is displayed in orange
- If a link is only to resources that are not part of the focus, then it is displayed in grey
First click on the icon at the top left of the visualisation, and select
focus as actions associated with the
click on a VM:
Then click on one of the VMs in the visualisation, it will then be integrated into the focus. You should have a visualisation that looks like the image below:
Selection of items to be displayed
Finally, it is possible to filter and select resources using the options provided by the "Map data settings" panel.
Selection of the date to be displayed
By default, the data used to generate the visualisation is that of the current day.
It is possible to use data from another time. To do this, you need to unfold the
a heatmap will appear. So in the image below, you can see that the current day is circled in red, which
means that it is used for visualisation.
By clicking on a time square, the corresponding time is selected as the date to be displayed.
Clicking again on an already selected time slot switches the selection to the whole day of which the time slot is part the time slot.
Details of the flows displayed in the visualisation
It is possible to display the details of the flows that have been used to calculate the visualisation.
To access it, click on the
Flow as shown in the following screenshot:
The details of the flows appear in the form of a table, where each row represents a flow with a source and a destination. By clicking on the icon on the far left of a stream, it is possible to see details of the communication ports used for the stream.
Finally, to the right of a stream there are several buttons that allow access to other DC Netscope components with the source and destination of the stream as a preset in the focus:
