Hello Michael Ho, Philip Zeyliger, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit

IMPALA-7694: Add host resource usage metrics to profile
This change adds a mechanism to collect host resource usage metrics to
profiles. Metric collection can be controlled through a new query option
'RESOURCE_TRACE_RATIO'. It specifies the probability with which metrics
collection will be enabled. Collection always happens per query for all
executors that run one or more fragment instances of the query.
This mechanism adds a new time series counter class that collects all
measured values and does not re-sample them. It will re-sample values
when printing them into a string profile to a max of 64 values, but
Thrift profiles will contain the full list of values.
We add a new section "Per Node Resource Usage" to the profile to store
and show these values:
Per Node Resource Usage:
lv-desktop:22000:
CpuIoWaitPercentage (500.000ms): 0, 0
CpuSysPercentage (500.000ms): 1, 1
CpuUserPercentage (500.000ms): 4, 0
- ScratchBytesRead: 0
- ScratchBytesWritten: 0
- ScratchFileUsedBytes: 0
- ScratchReads: 0 (0)
- ScratchWrites: 0 (0)
- TotalEncryptionTime: 0.000ns
- TotalReadBlockTime: 0.000ns
This change also uses the aforementioned mechanism to collect CPU usage
metrics (user, system, and IO wait time).
This change also adds a tool to decode a Thrift profile and plot the
contained usage metrics using matplotlib. Example:

This change also exposes the scratch profile within the per node
resource usage section.
Testing: This change contains a unit test for the system level metrics
collection and e2e tests for the profile changes.
