Performance monitoring is needed for a managed system containing multiple AIX7 LPARs. Which action enables historical data capture for the managed system?

The correct answer is D. Configure NMON to collect interval-based performance data. NMON is the standard AIX tool for interval-based performance data collection, enabling historical analysis of system metrics across LPARs.

Why each option

NMON is the standard AIX tool for interval-based performance data collection, enabling historical analysis of system metrics across LPARs.

AImplement IBM Systems Director Standard Edition.

IBM Systems Director Standard Edition is a systems management platform focused on provisioning and inventory, not specifically on capturing interval-based historical performance data for AIX LPARs.

BRun snap data collections periodically.

The snap command collects diagnostic and support data for problem determination, not periodic interval-based performance metrics for historical trending.

CConfigure the trace facility to capture details on system activity.

The AIX trace facility captures detailed kernel and application event traces for short-duration problem analysis, not ongoing historical performance data collection.

DConfigure NMON to collect interval-based performance data.Correct

NMON (Nigel's Monitor) is purpose-built for AIX performance data collection and can be scheduled via cron to capture interval-based snapshots stored as flat files. These files can later be analyzed with tools like NMON Analyser to review historical CPU, memory, disk, and network utilization trends. This makes it the correct choice for enabling historical performance data capture on a managed system with multiple AIX7 LPARs.
