In the "Monitored Devices" GUI display on the Dx NetOps Performance Management->Data Aggregator data source. I can delete a device one at a time. I want to delete a range. How do I do that?
Dx NetOps Performance Management (CAPM) all currently supported releases
You cannot do a multi-select and delete from the tree view, but you can from the search view.
You can also delete multiple devices at once using REST. It's documented further in the following Knowledge Base article.
KB : How to delete multiple devices in CA Performance Management (CAPM) Data Aggregator via REST API
This details how to use GET tunneling with REST to filter results from the Data Aggregator.
What you are doing above is deleting the items from the Data Aggregator (DA) data source. So the items will be seen in Dx NetOps Performance Center until the sync process runs with the DA data source (if that is your only data source and the device only exists in that data source.
You will see items in Dx NetOps Performance Center until the item has been deleted from all data sources and the sync process with those data sources has run. So say you also had Network Flow Analysis (NFA) as a data source, and the device was in both NFA and the DA. The device would be seen in Dx NetOps Performance Center until removed from both the DA and NFA.
