How to search ancestors with Items API

[Robert Zomborszki]

Hi,

 

I'm trying to use the Item API to search to find a signals that have a specific name and they are in specific part of the asset tree.

Here is what I am trying now and doesn't work:

 

This is how the item properties look like, and I'm unable to filter for this ancestors in any way.

What would be the filters syntax that would help me filter for the assets/ancestors?

 

Thank you for your time in advance

Hello Robert,

not sure if you can use the ancestors in the "filters" parameter. I think you would need to know the ID of the asset you are looking for and use it in the "asset" parameter of the /items endpoint.

Thank you Thorsten for checking it. I wanted to use it in the URL builder https://support.seeq.com/kb/R63/cloud/building-a-worksheet-from-url-query-parameters where the trenditems search can use this API

Hi Robert,

Thorsten is correct. This is how I would perform the search in the API Reference page:

where asset contains the ID of Area A from the Example data source, and I am search for the Temperature signal.

Hey Robert,

If you are trying to use the URL builder you could pass in the full path to the signal like so:
 

https://<your_seeq_server>/workbook/builder?workbookName=TestWorkbook&worksheetName=TestWorksheet&trendItems=Example>>Cooling%20Tower%201>>Area%20A>>Compressor%20Power

This will add the Compressor Power signal from the following path as a trend item:

Example >> Cooling Tower 1 >> Area A >> Compressor Power

Hi Chris,

thank you for you asnwer. I was adding AF elements like this, but the new development idea was that can we show also all of the Compressor Powers under the Cooling Tower 1, like how it is done in the Treeview.

Hi Robert,

You might be looking to apply the asset query parameter to the search:

The ID I've placed in the asset field was obtained from the info i in the Data panel for Cooling Tower 1:

The results are the same as if you had navigated to Cooling Tower 1 and searched for "Compressor Power" with the Exact Match checkbox checked.  Here's part of the result

You can also use SPy in Seeq Data Lab to have much finer-grained control over the search results, so if you haven't given that a whirl, I'd suggest checking it out - quite powerful!

Cheers,
