I have an aggregation rule which is showing the sum of all Dataminer network interfaces. Because this value is mBps I would like to multiply this value by 8 to have mbps.
I don't see there any option to make any calculation of it. How can I do it?
As Miguel indicated, this is not possible with the built-in functionality of Aggregation Rules. Besides a connector change, you could also consider making a dashboard with a GQI that does the aggregation and calculation for you through the custom operator. This Dashboard can use a dropdown that visualizes Views, which will affect the query and its results. In its turn, you can dynamically populate the dropdown if you're embedding the Dashboard in your Visio.
Do note that this option is only valid if you only want to view the outcome. With this approach, you cannot trend or alarm on it.
As far as I know this is not possible. A connector update will be required to add an extra column that displays the rate in bits per second.
I have a question about your use case. Most of the time we use bits per second for rates. Please could you let us know which connector are you using to perform this aggregation?
