We have used ZenOss for a number of years at this scale (40k+ devices, at i=
ntervals of 1-5 minutes). It is possible to do if you have the hardware and=
storage performance to throw at it. We used OpenNMS before that and had to=
change due to scale. During that time we evaluated a number of the big nam=
e and big dollar solutions and none of them seemed to scale any better with=
out significantly more hardware costs. =20
That's not to say ZenOss is perfect, we have plenty of headaches too.=20
