Hi Dojo,

On a country visual we show the SLA severity and availability of each region.
Now we want to see the average of the whole country. This should be a weighted average by taking the number of inhabitants of each region in account.

How can we achieve this knowing that we want to show this weighted average value on the same visual and monitor it?

Hi Jens,

Would it be possible to use the following placeholder in the shape:
"[Avg:X,Y,Z]"

Available from DataMiner 9.5.8 onwards.
Average of a list of entries, e.g. X, Y, Z (which will be parsed to numbers).

Also, it should be possible to use local session variables: push the number into a variable and use the variable in the placeholder.
Example: "[Avg:[var:numberX],[var:numberY],[var:numberZ]]"

Hi Matthias, that would work if the Availability is already multiplied with the number of inhabitants. Is there a multiply function in Visio?

As discussed, It would seem you will need a separate driver for this.
Why? parameter value can be used to monitor, to aggregate and to display in Visio.
