What's new in Cloudera Observability On-Premises 3.5.3

Resource efficiency analysis

You can now identify inefficient jobs or queries that over-allocate resources such as viewing the top queries or jobs by CPU wastage and memory wastage or viewing the CPU and memory consumption for the selected query. Using the resource efficiency analysis feature, you can ensure resources are allocated more efficiently, reducing waste and improving overall system performance.

You can use the query cost analysis to gain insights into costs associated with different resources used by the query.

For more information, see Query and job resource optimization using resource efficiency analysis.
