What I would like to do is graph per interface which includes all CoS Classes. I tried to find documentation how to do this with SNMP Data Query (xml). Unfortunatelly I did't find the peace of information I was looking for. Could be that I simply did't understand the maual...
I already know how to e.g. creat one graph for each CoS for each hard coded interface oid index(xml file attached). This would end up to too many graphs with too little information.
