About ResUsage Macros and Tables
You can use resource usage macros to report resource usage data. You can enable resource
usage tables to:
Observe the balance of disk and CPU usage
Obtain pdisk usage information
Check for bottlenecks
Provide an overall history of the system operation
Monitor the utilization of AMP Worker Tasks (AWTs)
Resource usage data is useful for the following purposes:
Measuring system performance
Measuring component performance
Assisting with on-site job scheduling
Identifying potential performance impacts
Planning installation, upgrade, and migration
Analyzing performance degradation and improvement
Identifying problems such as bottlenecks, parallel inefficiencies, down components,
and congestion
