WAPI call for hotfix information (show upgrade_history)

[#1]

Hi!

Does anyone know how to get the hotfix status for a Grid member through the WAPI? (if even possible)

Found some calls but related to upgradestatus and I belive those won't work....

hotfix : Upgrade process hotfix. The structure provides information about the status of upgrade process hotfixes.

Thanks in advance

This should work but it's not returning anything on my grid:

curl -k -u admin:infoblox -X GET "https://192.168.1.2/wapi/v2.9/upgradestatus?type=VNODE&_return_fields%2b=hotfixes"

Here's the schema, it describes each of the potential return values, including the hotfixes structure:

curl -k1 -u admin:infoblox -X GET 'https://192.168.1.2/wapi/v2.9/upgradestatus?_schema&_schema_version=2&_get_doc=1'
