Microsoft's upcoming release of Reporting Services, now in Beta 2, is an extension to SQL Server that could become a prominent tool for Systems Management deployments. In addition to custom reports for MOM 2004, reports can be created from any SQL Server or Oracle database, such as AppManager or MOM 2000. What IT managers will probably most like about Reporting Services is that it allows users to subscribe to reports on their own schedules.
It seems it can't report against OLAP databases, but this may be an incorrect assumption. For this type of enterprise data reporting, the best alternative may be Crystal Analysis Pro, which also offers managed subscriptions and web-based authoring. Crystal Decision was acquired in 2003 by Business Objects.
One Systems Management vendor who is planning on releasing a reporting product that uses Reporting Services is NetIQ. More on this to follow
