Data |
|
|
Data Sources:
(Source1) MRTG polls SNMP MIB of each monitored router
every five minutes for line utilization and network
errors on each router's attached links.
|
Data Specification:
(Data1) Five minute exponentially decaying sum of moving average
of input and output bits per second
(Data2) Percent of input and output packets in error or discarded at the router during each five-minute polling interval, multiplied by 1000.
|
Data Aggregation:
(Aggregate1): MRTG calculates average rate when available and
normalizes these to fit in a standard five minute time slot.
(Aggregate2): Error values can be calculated as an average of
a specified number of historical MRTG polled values.
|
Data Filters:
None used.
