Multiplexor Traffic Statistics
We monitor traffic volume on selected switches and chassis-based media converters
associated with multiplexors.
For each monitored interface, you may view
graphs showing the traffic volume in and out of that
interface over several recent time periods
(the past 31 hours, 8 days, 31 days, and 365 days).
In most cases, volume is measured by bit rate and packet rate.
Traffic graphed as "incoming"
(in
GREEN | )
represents traffic entering the monitored network interface,
while the traffic graphed as "outgoing"
(in BLUE | )
represents traffic leaving the network interface.
We also monitor some switches for CPU load and/or free memory.
The monitoring is performed with
mrtg,
rrdtool,
and
mrtg-rrd.
The display you see will be refreshed automatically by your Web browser every five minutes.
The interfaces we are monitoring are listed below, sorted by switch or converter chassis.
87 Prospect to HPCRC
These devices multiplex some traffic between the network core at 87 Prospect
and the HPCRC.
- metropolitan switch metro-87prospect
(cpu)
(memory)
This switch at the 87 Prospect network core
terminates aggregated links arriving from multiplexors 87Pros-(A) and 87Pros-(B),
which typically providing redundant paths leading the HPCRC.
This switch also acts to convert from CWDM to the media needed by the customer equipment on the main campus.
You may also view a table showing traffic volume on all interfaces ranked by
Bit Rate
or
Packet Rate.)
- metropolitan switch metro-hpcrc
(cpu)
(memory)
This switch at the HPCRC
terminates aggregated links arriving from multiplexors HPCRC-(A) and HPCRC-(B),
which typically providing redundant paths leading the 87 Prospect network core.
This switch also acts to convert from CWDM to the media needed by the customer equipment on the Forrestal campus.
You may also view a table showing traffic volume on all interfaces ranked by
Bit Rate
or
