Review the zonestat command:
zonestate – q physical – memory -R high -z -p -p “zones” 10 24h 60m
Select the option that correctly describes the information that is displayed by this command.
A.
It is a sample of dbzone’s physical memory usage taken every hour over a 24-hour period.
Only the top 10 samplings of peak memory usage are displayed.
All other utilization data is eliminated.
B.
It is a sample of dbzone’s CPU, virtual memory, and networking utilization.
Physical memory is executed from the report.
The sampling is taken every 10 minutes over a 24-hour period and peak utilization id displayed
each hour.
C.
It is a sample of dbzone’s CPU, virtual memory, and networking utilization.
Physical memory is executed from the report.
The sampling is taken every 10 minutes over a 24-hour period and displayed each hour.
D.
It is a sample of dbzone’s physical memory usage taken every 10 seconds and 24-hour period.
Only peak virtual memory usage and CPU utilization are displayed each hour.
All other Utilization data is eliminated.
E.
It is a sample of dbzone’s physical memory usage taken every 10 seconds and 24-hour period.
Only peak memory usage is displayed each hour.
All other utilization data is eliminated.
Explanation:
* (Not A, B, C): interval (here 10 seconds): Specifies the length in seconds to pause
between each interval report.
* duration (here 24 h)
* -R report[,report] (here high)
Print a summary report.
High Print a summary report detailing the highest usage of each resource and zone during any
interval of the zonestat utility invocation.
Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the
currently running zones. Each zone’s utilization is reported both as a percentage of system
resources and the zone’s configured limits.
The zonestat utility prints a series of interval reports at the specified interval. It optionally also
prints one or more summary reports at a specified interval.
The default output is a summary of cpu, physical, and virtual memory utilization. The -r option canbe used to choose detailed output for specific resources.
E
Definitely “E”, but…
“zonestate” command does not exist it’s “zonestat”
I managed to simulate following command on Solaris11.1 x86:
# zonestat -r physical-memory -R high -p -P “zones” 10 24h 60m”
It gave me outputs for physical-memory displayed every ten seconds (no CPU info, so “D” is wrong
When I changed 60m to 1m, after one minute “report-high:” with biggest memory use.
God bless.
