Performance Records
Performance Records
The FSP3000R7 records physical-layer measurements in 15-minute, 1-day, and 1-week
intervals, and records data-layer performance and service counters in 15-minute and 1-
day intervals. 15-minute intervals start at a whole hour, a quarter past, half past or a
quarter to an hour. For example, 02:00, 02:15, 02:30 and 02:45. The 1-day intervals
always start at midnight. The 1-week intervals always start at 00:00 from Saturday to
Sunday.
When the secondary state of an entity is “Unequipped”, “Mismatch” or “Fault”,
performance recording for that entity is disabled and the content of the record so far is
discarded. This is, for example, the case when an SFP transceiver is unplugged.
For each of the record types you can do the following:
• View the content of the current record while it is being created. This is called the
Current Record.
• View the records after the recording interval has ended. A number of these records
are stored. The collection of these records is called the History Record.
• For the data-layer records only, reset the Current Record or the Current and History
Record list, if relevant.
Record Types
Current 15-Minute Record
The current 15-minute record contains the measurements or counters for the ongoing 15-
minute interval as well as the elapsed time of the ongoing interval. When the ongoing 15-
minute interval is completed, the content of this record is transferred to the historic 15-
minute record, together with a time stamp to identify it. Then the counter content is reset
and a new "current 15-minute record" is started.
History 15-Minute Record
The history 15-minute record contains the previous 15-minute records, as well as
information about the validity of each of these records. A maximum of ninety-six previous
15-minute records are stored. The ninety-seventh 15-minute record overwrites the oldest
stored record. Thus, the historic 15-minute records together represent a 24-hour history.
Current 24-Hour Record
The current 24-hour record contains the measured contents of the counter for the ongoing
24-hour interval as well as the elapsed time of the ongoing interval. When the ongoing 24-
hour interval is completed, the content of this record is transferred to the historic 24-hour
record together with a time stamp to identify it. Then the counter content is reset and a
new "current 24-hour record" is started.
History 24-Hour Record
The history 24-hour record contains the previous 24-hour records, as well as information
about the validity of each of these records. A maximum of thirty-one previous 24-hour
records are stored. The thirty-second 24-hour record will overwrite the oldest stored
record. Thus the historic 24-hour records together represent a 1-month history.
