Hi Daniel!!
Thanks for using Wazuh, and thanks a lot for your feedback about 4.2.
Regarding your needs, there is no easy way to achieve this. They are migrating OpenDistro to OpenSearch, and they are slowly deprecating OpenDistro so there will be no upgrades over OpenDistro but for OpenSearch they are working on this feature to send reports as notifications you can follow this
here.
Community mentions
https://github.com/sentinl/sentinl/ as an option but it is no longer maintained too.
Maybe you can perform some script to get reports instances from the opendistro API but there is nothing about it in the official documentation or community
Please let me try to look for some useful trick to achieve this.
