Can we customize HUM to plot graphs based on our need. We are trying to pull the DSP used in a MGW AS5400XM device at any particular instance, we got the OID for the same but it is "18.104.22.168.22.214.171.124.126.96.36.199.1.8". But the issue is that it is giving the call usage for each DSP, can we get the total channel usage adding all the DSP in a MGW. Also we need to take count of total DSP channel available in the chassis against which the used channel should be plot on graph. This would help us to plan the resource needed. Need to know how to customize HUM for adding all instance value to plot the sum of values as a graph and also to plot a graph against another value which is again sum of various instances ( total channels for each DSP to be added to get the total channels in MGW ). Kindly do suggest on how to get the same done and is it possible to plot the same in HUM 1.1.
