We can see the events when we run the discovery manually from the console.
0x25e0002 and 0x25e0003 are seen when we run when reconfigure device is selected from the oneclick console.
Spectrum : All Supported Versions
There is no specific event for when a scheduled discovery runs, or creates a device.
We do get the generic event
0x10201
A model has been created. The model is xxxx of type xxxx created by Spectrum@hostname.
You can also see when the model was created in the model and history tabs of the discovery configuration.
