I need to accomplish the following

my organization has 3 links consisting of one link of 7Gbps, two links of 2Gbps each, The total bandwidth available for the uplink is 11Gbps (7+2+2)

According to the Department of telecommunication rules i need to calculate the aggregate utilization of all the three links on a monthly and quarterly basis

if this is possible with Netxms, Please guide me about how to set up Netxms to accomplish this task

if possible can i also get alerts if the combined utilation of all the three links cross the threshold of 90%.

I also need to calculate the aggregate average monthly and quarterly latency for these up links

cuurently i use a ping tester that runs a scheduled ping query of 1000 packets to the hosts every date and dumps the data in sql database, then i have a custom made web application to fetch the data as below 

Group Name : Upstream ISPs

IP Address         Host Name BUffer Size PacketSent Packet Lost % Packet Lost % Availibility Avg Latency
X.X.X.X target1 32         1000         0         0.00         100.00 4.10
Y.Y.Y.Y target1 32         1000         0         0.00         100.00 1.50
Z.Z.Z.Z target2 32         1000         0         0.00         100.00 2.17

Total                 32         3000         0         0.00         100.00 2.59
