I have setup mrtg to monitor traffic for a specific Ethernet interface on a
Cisco Catalyst 6509 that connects two campuses over a fiber WAN link. The
third party fiber provider says they are giving us 100Mbps across the fiber,
but we need to verify what we are actually getting. I have come to realize
that simply monitoring the WAN interface gives me a nice graph and actual kB/s
(or MB/s) data passed, as shown below; however, the percentages are based on my
Maxbytes value that is based on what the ISP says we are getting (100Mpbs or
12.5MB/s). In other words, I can change the percentages by adjusting MaxBytes.
Is there any way to use mrtg to verify the available bandwidth over the WAN,
or do I need a different tool?
Max Average Current
In 776.4 kB/s (6.2%) 143.6 kB/s (1.1%) 89.3 kB/s (0.7%)
Out 11.2 MB/s (89.5%) 542.1 kB/s (4.3%) 819.2 kB/s (6.6%)
Thanks for any assistance,
Rodney Tyler
