[jira] [Comment Edited] (IMPALA-12182) Add Impala daemon's CPU utilization time series graph for RuntimeProfile's sampled values
[ https://issues.apache.org/jira/browse/IMPALA-12182?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17728695#comment-17728695 ]

An example containing realtime updates, where intentional stress testing was done on the coordinator node. The samples do not contain timeseries labels, but can be shown with with some experimental support.

> The RuntimeProfile contains samples of CPU utilization metrics for user, sys and iowait clamped to 64 values (retrieved from the ChunkedTimeSeriesCounter, but sampled similar to SamplingTimeSeriesCounter).
> It would be helpful to see the recent aggregate CPU node utilization samples for each of the different nodes.
> These are sampled every `periodic_counter_update_period_ms`.
> AggregatedRuntimeProfile used in the Thrift profile contains the complete series of values from the ChunkedTimeSeriesCounter samples. But, as this representation is difficult to provide in the JSON, they have been downsampled to 64 values.
