Aggregated Data Views

Aggregated Data Views are used to aggregate data from one or more Measurement Jobs and display this aggregated data. For example, a site may have two connections to JANET, and it may be desirable to show the total amount of traffic going into and out of their two connections.

Viewing Aggregated Data View Details

To view the details of an existing Aggregated Data View, you must navigate to it using either the Manage Aggregated Data Views Page (select "Graphs" from the Menu Bar then "Agg. Data Views" from the Side Menu), the Netsight Explorer, or search for it using the Search page. Click the appropriate Aggregated Data View to show the View Aggregated Data View Details page. This page shows the details of the Aggregated Data View, including:

• The Aggregated Data View's Name, Description and Location within Netsight.
• How the data is being aggregated (e.g. Minimum, Sum, etc.)
• A list of all component series that are aggregated together in this view. Aggregated Data Views can have multiple series, with each series aggregating together a number of component series.

Creating and Editing Aggregated Data Views

To create edit, and delete Aggregated Data Views, write access must be enabled on the system. You must also have been granted the appropriate permissions to carry out the operation.

Creating a new Aggregated Data View

When write access is enabled, you can access the Create Aggregated Data View page in two ways. One way is to locate the Aggregated Data Views section in a Folder in the Netsight Explorer and click on the "New" link. The other way is to select "Graph" from the Menu Bar, then "Agg. Data Views" from the Side Menu and click on the "New..." link. In either case, this leads you to the Create a New Aggregated Data View page.

• Enter a Display Name for the Aggregated Data View. If you wish, you can also enter a description.
• Select the Aggregation Type to use from the drop-down list.
• Set the Admin Location. You can browse for this using the Explorer. Alternatively, if you've arrived here by clicking the "New" link in the Aggregated Data Views section of the Explorer, this will be filled out for you.
• If you wish, choose a label for the Y-axis of the graph. If you don't specify a Y-Axis Label, the system will use the default label for the units that the data is measured in.
• Choose the data sources for the View as described below.
• Click "OK" to create the Aggregated Data View
• Click "Cancel" at any time to abort creation of the Aggregated Data View.

Selecting the Data Sources

At the bottom of the page is a list of 'series'. These group together the data sources that are aggregated together. The "Add new series..." link will add another series to the page.

You can add a data source to a series by either:

• choosing a reporting path, and then choosing a source of data from a job that targets one end of the job.
• choosing a job, and then choosing a source of data from this job.
• choosing a node, and then choosing a source of data from a job that targets this node.

You can click "Remove" against any of the series you've chosen to aggregate, and this will remove them. You can also click "Delete" beside a series name to delete an entire series.

Note that you can only choose to aggregate sources that are measured in the same units as one another. Once you have chosen one series to aggregate, you will only be given the option of adding other series in compatible units.

• Choose the data source you want to see from the third drop-down and click "Add". The data source is added to the list to be displayed at the bottom of the page.
