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
