> What metrics are used to measure networks and network
Peering and Transit Cost
Peering and Transit Cost / bit
Change Management Practices and Successes
Ave Uptime/Device by Type
Ave # Trouble Tickets / Time
Customer Call hold times and call lengths
Average Backbone Circuit Utilization
Peak Backbone Circuit Utilization [maybe P95 of circuits, or top 20 busy]
Packet Loss and Latency within network
Packet Loss and Latency outside of network on Internet
# of employees required
Ave # of employees / device
Capex $$ / POP
Capex $$ / bit or bps
Ave Packet Size
It's interesting to note that two schools of thought exist on defining
the denominator in many cases - rate (bps) and volume (TB/month).

Specific instances of some of above.

Although folks would love to throw money at vendor XYZ to
produce SAS-like reports w/ a big dial, I don't believe such
a tool exists.
At the end of the day, the formula about making a profit
without too many upset customers and no financial chicanery
is the simplest.
In terms of greater geo-telco-politics, a particular engineering
group or operations group may pick out 2-10 metrics above and use
those to justify certain things.
The vast majority of the metrics above can be gotten from
simple ping scripts and snmp query scripts stuffing data into
databases, and running DB reports.
A trouble ticket system such as remedy or RT2 or others can
also serve as a workflow system and provide useful statistics.
