OK - network connection up or UP/DOWN with list of when its down and for how long and SLA based on amount of time its been down or more commonly time_up/time_down*100
- - response time / latency
ok ping latency graph for user view with SLA based on maximum average latency over given time period
- - utilization
How is that part of SLA? Or do you mean you gurantee that your own upstream network connection would not be overutilized?
- - accuracy and errors
accuracy of what? what type of errors, packet drops?
- - five nines, six nines , take your pick and define your own holy grail.
$ echo "60*24*365*(1-0.99999)" | bc -l 5.25600 You wish to tell me you guarantee network connection to customer to be down for no more then 5 minutes during the year? Yeh, right :) (but don't let me discourage any of you in trying to achieve it!) -- William Leibzon Elan Networks william () elan net
