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.
