A Cluster target represents an entire Big Data Discovery cluster deployment, including the Studio and Dgraph instances. The All Targets page provides a table that lists the Big Data Discovery clusters and corresponding status (up or down).
For example:
Clicking a Cluster target in the table displays that cluster's home page. On this page, you can see the status and name of each node in the cluster. In particular, on the Cluster page you can see which Dgraph is the leader node (this is useful because some of the Dgraph administrative operations, such as merging index data, can be run only from the leader node).
Some of the regions on the Cluster home page are standard to all
Enterprise Manager plug-ins — such as the
Incidents region. Other regions, such as
Studio Query Search, are unique to the plug-in for
Oracle Big Data Discovery. For example:
Clicking the
Studio Query Search region displays search
features that allow you to search all Studio queries for a range of dates and
identify any queries that took longer than the number of milliseconds you
specify. For example:
You can also export these results to a file in Excel.
