ReportingSite Extensible Attribute
NIOS defines the ReportingSite extensible attribute for use by the multi-site cluster reporting configuration. You must associate a ReportingSite extensible attribute value with the reporting members defined in the cluster. For more information, see Assigning a ReportingSite Reporting Site EA Value to a Multi-Site Cluster. Note that your multi-site cluster configuration is invalid unless you assign ReportingSite values to all the reporting members that are part of the cluster.
You can add up to five ReportingSite extensible attributes, and view and edit the ReportingSite extensible attributes in the Administration tab -> Extensible Attributes tab in Grid Manager. You can view the ReportingSite extensible attribute values in the Grid -> Grid Manager -> Members tab in Grid Manager. The ReportingSite column is not available if you customize the Results table. You can enable the ReportingSite column by selecting Columns -> Edit Columns. For information, see Customizing Tables. You can also use the Group Results function to group reporting members that contain the same ReportingSite extensible attributes. For information about grouping members by extensible attributes, see Grouping Members by Extensible Attributes.
As illustrated in Figure 40.6, the ReportingSite value "site1" is assigned to a site within a multi-site cluster and to the reporting members RM1, RM2 and RM3. The ReportingSite value "site2" is assigned to a different site in the cluster and to reporting members RM4, RM5 and RM6. If the search head goes down, the Grid Master automatically chooses an available reporting member in the same site to be the search head.
