Hi, I have cacti and NNMi monitoring an interface but I cacti gives me higer metrics, what would be the best way to check if cacti is graphing the right values for bandwidht an throughput, a linux command maybe?

Hey there a couple of things you can do

1.) Use the data source debug to see what cacti is receiving before going to the graph
2.) You can do a snmpwalk between the two systems to see what the counters are
3.) Also make sure you are comparing bits to bits between nnmi and cacti that is if NNMI is showing a graph in bits then make sure cacti is showing in bits as well

If you need help reach out to me
