How to find the total number of calls on one trunk group per day

[telecomadmin12]

I want to know how many calls I have on one trunk group in one day. I guess the list measurements trunk-group hourly would be the command to go with, but I have trouble reading it. Would the 'Total Seize' column give me the total number of calls in one hour (e.g. 16 calls from 3pm to 4pm as shown below)? And what would be the difference to 'Total usage'?
