Understanding Performance Management

Understanding Performance Management

Performance management can collect the following data:
  • Interface traffic statistics, for example, the number of packets sent and received on an Ethernet interface

  • Protocol packet statistics, for example, the number of a specific type of protocol packets

  • System running parameters, for example, CPU usage statistics

The statistics collection function involves various statistics collection tasks, each of which can be bound to multiple statistics collection instances. After you create a statistics collection task, the system periodically collects data in the instances bound to the task and calculates the statistical counters in each statistics collection cycle. The statistics are periodically saved to statistics files.

The system uses FTP or SFTP to upload statistics files to a remote performance management (PM) server. Statistics files can be uploaded in either of the following modes:
  • Active mode: The system periodically generates statistics files and automatically uploads the files to the PM server.

  • Passive mode: The system periodically generates statistics files. When the system receives a file uploading instruction from the network management system (NMS) or a file uploading command is executed, the system uploads the statistics files to the PM server.

Using FTP to upload performance statistics files is insecure. Therefore, using SFTP is recommended.
