Description
The performance information is accumulated during a certain time span, called a
period. After a period, the accumulated performance information is written into a
buffer. Then a new period starts. An interval contains several periods:
• To cover a 2 hours interval, 8 periods of 15 minutes are kept.
• To cover a 24 hours interval, 12 periods of 2 hours are kept.
• To cover a 7 days interval, 7 periods of 24 hours are kept.
The buffer in which the information is stored, is a circular buffer. I.e. every period
(15 minutes, 2 hours or 24 hours) the most recent measured and calculated values
are added, and the oldest values are lost.
In this case, the performance information is kept since the latest cold boot of the
Crocus SHDSL G703. This can be considered as a performance information summary.
The Crocus SHDSL G703 does not contain a real-time clock, therefore time information is related to its
internal clock. To allow you to situate the time intervals in the real time, the sysUpTime attribute is returned
together with the performance information. It reflects the time since the latest cold boot of the Crocus
SHDSL G703.
Only the available performance information is displayed. If the interrogation happens shortly after boot,
no values are displayed. For example for the 24 hours intervals, the new performance information is
available only when a complete time span (i.e. 2 hours) has elapsed.
