-----------------------------------
Summary: Add system resource utilization (CPU, disk, network)
timelines to profiles
Key: IMPALA-7694
URL: https://issues.apache.org/jira/browse/IMPALA-7694
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 3.1.0
Reporter: Lars Volker
We often struggle to determine why a query was slow, in particular if it was
caused by other tasks on the same machine using resources. To help with this we
should include timelines for system resource utilization to the profiles. These
should include CPU and disk and network I/O. If it is too expensive to include
these in all queries we should add a flag to add these to a percentage of
queries, and a query option to force-enable them.
