I am bale to do this easily in PRTG but I haven't found a way to do it at all in NPM. Below are the screenshots from PRTG and of it sensor setting.
This is what I was able to utmost achieve in NPM. A table with current values and I have not been able to chart them overtime.
And this is the screenshot of OID's(.1.3.6.1.4.1.25461.2.1.2.3.10) I want to chart for each firewall zone.
PRTG is running in trial and NPM is what we have paid for, so would really like to do it from a single system.
