Is anyone out there creating alert rules using the sdk and python or powershell? I don't find anything searching the usual places and not sure if it is actually possible, but it seems like it would be.
You can take a look at the Export and Import verbs described here:
https://github.com/solarwinds/OrionSDK/wiki/Alerts
The alert definitions are formatted as XML, and the structure of that XML is not documented, but it may work depending on what you are trying to do. See these threads for additional detail:
How to create and edit alert trigger conditions in API ?
"Proper" way to export/import Alert Configurations via SDK?
Full alert definitions including Alert trigger actions cannot be created net-new from the SDK.
