Cluster overview

The Cluster Overview tab shows a summary of the cluster's connection string, active alerts, and recent cluster activity.

If the cluster is a single node or primary/standby high-availability cluster, the overview first shows the Quick Connect section.

If the cluster is a distributed high-availability cluster, the overview first shows the Data Groups section.

Getting your connection string

The Quick Connect section provides a full psql command line with a connection string configured for the cluster and a user with the edb_admin role to connect to the edb_admin database. You can copy this command and paste it into a terminal to connect to the database. (You need the password for the edb_admin user to connect to the database.)

Data groups

Under Data Groups, view a summary of the data groups and witness groups in the cluster. Each group is listed with a status badge, the data group's name, and a Data Group or Witness Group label.

The status badge indicates the status of the data group. A green circle with a white tick indicates the data group is healthy. The other information displayed includes the time since creation, Postgres server type and version, and number of nodes in the data group.

• To edit a data group's node settings and database configurations, next to the data group name, select Edit Data Group.

• When you have more than one data group, you can delete data groups. (You can't delete all the data groups.) From the ellipsis menu, select Delete Data Group.

• To restore a data group you deleted, from the ellipsis menu, select Restore Data Group.

Under Quick Connect for the data group, you can get the psql command line connection string for read-write and read-only connections.

Select Read-write or Read-only to see the psql command line with a connection string configured for the data group and a user with the edb_admin role to connect to the bdrdb database. To connect to the database, you can copy this command and paste it into a terminal. To do so, you need the password for the edb_admin user.

To toggle the display of a cluster architecture diagram, select the Cluster Architecture Diagram heading. (The diagram is hidden by default.) This diagram shows the architecture of the cluster, including the data groups, witness groups and proxies, and the interconnection between them.

Active alerts

The number of currently active alerts are listed in three categories: High Severity, Medium Severity, and Low Severity. Selecting the displayed counts opens the Monitoring tab, where you can view the alert details.

Cluster activity log

You can view the recent activity logged on the cluster, including creation, configuration updates, and other major events in the cluster's lifecycle. Active elements don't appear here. For more details on the events, select the Logs tab.
