Network visibility

[Nat Fogarty <nat () inband io>]

Hi there,

I'm interested in what you good folks do in terms of network visibility.

My interests are around Service Provider space - visibility for IPoE,
PPPoE, TCP(User Experience).

I use a product called "VoIPmonitor" for all things VoIP - and it is one of
my favourite tools.  It is a web gui for sip/rtp/etc.

Is there a similar tool in the Ethernet(L2)/IP(L3) space?

Are operators using tcpdump/wireshark for this - or is there a
voipmonitor-esque tool out there?

Cheers,
Nathaniel
