3.3.3.9 Common Performance Management (OPM)
OPM collects and provides the performance data for the upper management system
operator to know the outdoor SPI-2210 performance. The OPM collects the event
generated during the system operation and the performance data and transmits them to the
management system. The collection cycle of the statistics data of the actual OPM can be set
as 15 minutes, 30 minutes, 60 minutes, and if the entire statistics file of the binary format is
created every 15 minutes, the management system collects it periodically via the SFTP.
