Viewing Statistical Reports Using the On-node System Reporter
This section provides instructions on using HP 3PAR CLI commands to generate reports of historical
capacity and performance information that has been collected by the on-node System Reporter.
The commands here are a subset of the statisics commands available. For a complete list of statistical
reporting commands, see the HP 3PAR Command Line Interface Reference.
In nearly all cases, the reports can be refined by specifying the following:
• A start time for the report
• An end time for the report.
• ◦ Whether to view the data across a specified time period or at a specific time. For this
report, you can also specify attributes by which to group like items together.
• What granularity of samples to use in the report (high resolution – every 5 minutes, hourly,
or daily).
Viewing Statistical Report for Region I/O Density
To view a statistical report for region I/O density, issue the srrgiodensity command. Data
output can be further refined by the common fields listed in “Viewing Statistical Reports Using the
On-node System Reporter” (page 123), in addition to specifying a CPG name or an AO configuration
name. The report contains the distribution of IOP intensity for the LD region for a CPG or AO
configuration.
For complete details about srrgiodensity command options and for sample command data
output, see the HP 3PAR Command Line Reference.
Viewing Statistical Reports for Used Capacity (Space Reports)
To view statistical reports for capacity usage over time, issue the following commands. Most of
these commands also allow the specification of the type of drive and RAID type for which to
generate the report:
sraomoves Describes the space moved by Adapative Optimization over time between tiers
in an Adapative Optimization configuration.
srcpgspace Describes the space consumed in a CPG over time.
srldsapce Describes the space consumed by LDs.
srpdspace to describe the space consumed by physical disks.
srvvspace to describe the space consumed by virtual volumes.
For complete details about command options and for sample command data output, see the HP
3PAR Command Line Reference.
Viewing Statistical Reports for Performance
Performance statistical reports are available for the following:
• Cache memory
• CPU
• LDs
• Links
• Physical disks
• Ports
• Priority optimization
• Virtual volume LUN exports
