Cost (Only for EMR and Databricks platforms)

In the EMR version, the cost section shows the cost and number of deployed clusters, monitored by Unravel, as well as the total cost and the total number of clusters in your environment, for a given time period. Daily values of the same KPIs are shown in a trend over the same period. Unravel also provides insights to reduce cluster cost, such as instance type recommendation, and showing top groups by cost, nodes that use spot instance pricing and long-running clusters with significant idle time.

In the Databricks version, only the cost and number of clusters monitored by Unravel are available, broken down into all-purpose and job clusters, with daily values shown in trends for a given time period. Besides instance type recommendations, top groups and clusters by cost are shown, as are apps caught by AutoActions for exceeding costs.

Resource Efficiency

This section provides the total number of finished and failed apps and the corresponding resources, for a given time period. It also shows top users by resource, apps with insights to improve resource efficiency, apps caught by AutoActions for using too much resource, and the number of tables with no app access recently.

App Acceleration

This section identifies apps with insights to improve app speedup, including specific insights such as skew, inefficient joins, queries not leveraging partitions, and so on. It also shows apps caught by AutoActions for running for too long.

The values can be shown for the last completed 1, 7, 14, or 30 days. You can also choose a custom range to view the values. Each widget has an info icon that provides a detailed description. Some have links that redirect users to other pages in Unravel for further drill down.
