Description

F.e. if the device-type is vmanage, then admintech is generated for all the vManages in the cluster.

{
   "exclude-cores":true,
   "exclude-logs":true,
   "exclude-tech":false,
   "device-type":"vmanage"
}

Needs special implementation for collecting files generated in this way.
In normal case generate request blocks until single file is generated and returns file id, so it can be downloaded in next step.
In case device-type is sent, request will return immediately. As client we need to identify newly generated files and download each file in separate GET request.
