Hi,
Im stuck at creating a simple parameter table, which shows the "bitrate" value from a table from elements of the protocol "Harmonic NSG9000 40G".
After adding the bitrate parameter it state that "table requires a valid Dataminer ID".
But there is no way to provide the table a Dataminer ID.
Dataminer Setup is 3 DMA's in a cluster, if this is relevant.
Hi Thomas,
The error that you are seeing is shown when the parameter table component doesn't know what element to show. This happens when you add a protocol parameter to the table but no element. You can fix this by adding the element as a filter or by instead using the element parameter.
Note that the component can only filter on 1 element at a time. If you want to show the table for multiple elements, I suggest using GQI instead:
You can create a query to 'Get parameters from elements where' for a specific parameters of a specific protocol version. This will then allow you to 'select' the relevant columns from the result. The query can then be visualized in a Table component.
The query
The resulting table
Join for the element names

GQI stands for Generic Query Interface, this is a generic way to retrieve and manipulate data from inside (& outside) your DMS. More info can be found here: https://docs.dataminer.services/user-guide/Advanced_Modules/Dashboards_and_Low_Code_Apps/GQI/About_GQI.html. I have updated my answer with an example.
ah okay, the example helped a lot.
is there a way to add the element name instead of the elemend id?
or just adding the element name would also okay.
as the element name is not a parameter of the protocol, i cannot select it.

The element name is indeed not included in that data source. You can however use a join operator (https://docs.dataminer.services/user-guide/Advanced_Modules/Dashboards_and_Low_Code_Apps/GQI/Query_Operators/GQI_Join.html) to join the rows on the ‘Get Elements’ data source. This second source will provide the name. I have added this step to my example
okay, i want the same parameter from multiple elements.
So i need a GQI. But what is it precisely? Is it another Visualization or something other?
