performance statistic logs and send logs in real time to the remote syslog server. The server analyzes these logs to evaluate
the device performance.
By default, the periodical logging interval is 15 minutes. To enable the server to collect all performance statistic logs at a time,
you need to set the log periodical logging intervals of different statistic objects to a common multiple of them. Currently, the
interval can be set to 0, 15, 30, 60, or 120. 0 indicates that periodical logging is disabled.
