Since 2 weeks now I’m running the newest version of OpenNMS, the 1.12.1 . There is a really nice improvement that this new release brought: fancy/awesome graphs!! Now they seems more “precise” and even the perceptions of colours give at a first sight an idea of what’s happening: bad or good.

In the pic above you can have a look at the CPU graph from a Fortigate. What a nice view.

Now I would say that it’s definitely the way to follow, upgrade your graphs, trash them all and get new ones.
P.s: I would like to thanks the HP Raid controller that screwed up all the filesystem that day, otherwise I wouldn’t have done the installation of OpenNMS from the scratch and get as result this nice view 😉
