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 Viewing Statistics 123
