[mrtg] Re: [Newbie]: Text, but no graphs

[Joe Loiacono]

Thanks Alex,

I run mrtg via cron and any errors are returned via mail. I haven't seen
any (I have seen errors when I didn't have something set up right) and the
graphs are getting updated with the text correctly. Just the plots don't
show and the y-axis scale is pretty weird. The graphics created are 'png'
files. Is that expected (i.e., as opposed to 'gif')

Thanks,

Joe
