Hi Dojo Folks,
I was wondering if anyone here had the same issue.
I want to aggregate 2 indexes of the same parameter of a network element (2 interfaces bitrate) in a sum, just like what we can do on views aggregation rules feature, but instead of doing that for all the elements in a view, we want to do that for each element in a view, aggregating only 2 interfaces each.
Do you know a way of doing that without much scripting and protocol editing?
Best regards.
Hi Euler,
You can calculate the SUM in a visio file using shapedata ParametersSummary.
The syntax is explained here.
Example:
Sum|6/97148:176|6/97149:176|6/97150:176|
As you can see in the example, this shapedata let's you specify the Operation (SUM) and the element and parameters to be used as operands.
Hope that helps.
Thanks Miguel, and sorry for late reply (weekends 😉 )
I´ve tried you suggestion and it´s very welcome to show things in visio and visual for each element. its a good thing to get on a view or something like that.
My main purpose on data aggregation is to be able to generate new trending and alarms just like the aggregation rules. Although your suggestion get that in a visual way, I´m not sure if it can be used for trending and alarming.
Do you know something about this kind of use on parametersSummary also?
Best regards
Hi Euler, if you want to be able to trend and alarm then the aggregation will need to be done at the driver level…The driver can be updated to do the SUM calculation and store the value in a parameter.
As you already know, the Aggregation engine cannot be used in this scenario since it is intended to aggregate data across multiple elements (by views) but in your case you want to aggregate data from the same element therefore I am afraid that will need to be done in the protocol.
Thanks Miguel,
I´ll try that.
Hi Euler, did the answer I gave you helped you achieve your goal? We’d love to read your feedback. Regards,
