[SunHELP] mrtg question

[sunhelp at sunhelp.org]

Does anyone know whether I can use MRTG for hosts. (I understand this
freeware is for router).
Does anyone have success case of cfg file? Can you let me know?
Also when I use cfgmaker to create cfg file, it always say:

root at skyline # cfgmaker vzread at absdat1
--base: Get Device Info on vzread at absdat1:

(but I can use snmpwalk to get info of absdat1)

Thanks
