Version 7.2

New features

  • Agent [B883]: new supported backend: Azure Data Explorer (ADX) (via Azure Event Hubs).

  • Dashboards [I1151]: aligned the hostinfo lookup across sourcetypes in props.conf to always output the same fields.
  • Dashboards [I1174]: the Security Score dashboard only displayed a maximum of ten SCI categories. Any additional categories were merged into “OTHER”.
