Important: The ADS Repositories attribute in the engine or server determines where the device sends historical information. The Default ADS Repositories attribute in the Site object defines where historical data is stored. By default, these repository attributes are blank. Be sure to enter the address or name of your repository device (typically the Site Director) in these attributes to ensure that you do not lose historical data. For the Site Director itself, leave the ADS Repositories attribute blank if the Site Director also serves as the repository. The Default ADS Repositories attribute defines the location of the ADS repository for all devices on the site that do not have the ADS Repositories attribute defined on their own. The ADS Repositories attribute, once defined on a network engine, overwrites the Default ADS Repositories attribute of the site for that engine.

Three new SQL databases: MetasysValue, MetasysFault, and MetasysFaultTriage were introduced at Metasys Release 11.0. To activate the databases, license the associated Metasys features. These include, Potential Problem Areas, Fault Detection, and Fault Triage. The MetasysValue and MetasysFault databases self-maintain and store a rolling seven days’ worth of data. These databases are not monitored or managed by Metasys Database Manager.

A repository provides long-term storage for historical data. Typically, the ADS/ADX configured as the Site Director also provides the individual repositories for trend data, event messages, audit messages, annotations, reporting, spaces authorization, potential problem areas, fault detection, and fault triage data. Individual repositories may reside in the SQL Server database. For a split ADX, the repositories are on the database server where the SQL Server software is installed. You can install a split ADX where the database server computer stores all historical data.

Note: The ADS-Lite cannot be a Site Director for other ADS or ADX servers.

The following table lists the ADS/ADX repositories, the corresponding online Metasys SMP Help (LIT-1201793) or Metasys UI Help (LIT-12011953) topic, and the corresponding file name. The next sections describe the repositories in more detail and suggest ways to optimize the repositories.
