If a network device supports the performance management feature, the network management system (NMS) can deliver performance management tasks to analyze device performance data, as shown in Figure 1.
The user configures a statistics collection task and specifies the monitored objects on the NMS or command line interface.
The device performs the statistics collection task to collect data of the specified objects, and generates statistics files.
The device uploads the statistics files to the performance management server automatically or following the instructions from the NMS or commands executed on the command line interface.
