Greetings:
I've installed netmrg and gotten most things running, I am getting "nan" for the byte count on my graphs. Any help or direction would be appreciated. |

| "nan" values on a graph mean that either no data has been written to an RRD file, or that the data written was "unknown." The best way to determine the cause of this is running "netmrg-gatherer -sm" while logged in as the NetMRG user. The output should be safe to post here if the problem isn't evident. |

Nope; that doesn't look immediately helpful.
What are the permissions on your rrd files, or the directory that the rrd files are in? Can the user netmrg is running as write to them?

That seems to have been it. One other thing though, the ping time script seems to need some modification for my debian box. I had to remove the -w and -i 0.2 options. The regular expression in the script is (I assume) supposed to render an interger value and it is not. I've been looking at the perldocs to find the answer but a shortcut wouldn't hurt  )
Thanks for all you help.

All seems to be working now. Just need to get all graphs to show up in slideshow. More time in the documentation I guess.
Thanks again,
