Viewing the NUMA Refined Analysis Result

Prerequisites

A NUMA refined analysis task has been created and the analysis is complete.

Viewing the NUMA Refined Analysis Result

1. In the System Profiler area on the left, click the name of the target analysis task.

   The node list is displayed.

2. Click the name of the target node to view the analysis results.
   Click the node name. The general report of the Summary tab page is displayed by default, as shown in Figure 1. Table 1 describes the parameters.

   

   • The Summary tab page displays tuning suggestions and scores the NUMA status. The NUMA score is used to measure the NUMA memory access status of the entire system. The score ranges from 0 to 1. If the score is 1, all memory access operations are local. A score closer to 0 indicates more cross-NUMA remote access.
   • Click to locate the latest report. When all reports are generated, this icon becomes unavailable.
   • Click a time point on the timeline to view the data of a report interval. You can also click General Report to view all the data collected.
   • Move the mouse pointer to to view the tuning suggestions for the current process.
   • In the Top 10 Memory NUMA Access Processes area, click a process ID to view the process details. Click the button before the process ID to view the thread information, and click a thread ID to view the thread details.
   • In the system memory NUMA access matrix and process memory NUMA access matrix, you can move the mouse pointer over different color blocks to view detailed data of each access mode, including the memory access type, node access, traffic, and the percentage of the traffic to total system access traffic.
