I have one query regarding MRTG on Windows 2003 Server platform,  I have been using mrtg from long time and it's working perfectly recently I have installed RRD Tools on mrtg-2.16.4 version, everything seems fine except when I am applying this command "perl mrtg test.cfg" it should produce the html images using rrd format but it's not as I am unable to get anything, can someone tell  how to get this html images after applying the command and path of the folder I mean where this rrd format images stored.

 

 

Regards,

> I have MRTG setup and running well on my Mac. What I really want to do is see how much traffic is coming and going to the Internet. I am monitoring my Apple Airport Extreme base station and Zyxel P660WHP-D1. I could get the answer from either of these two devices. Obviously the Zyxel would be the best place, but all traffic to the Internet has to go through the base station to get to the Zyxel.

> I looked at the IMPORTS line in the squid 3.1.8 MIB file and there is nothing there of concern. It is acting more like the MIB file couldn't be read at all. Check the permissions on the file and its directory path. Judging from your example, you're running 'snmpget' as root. Try running 'snmpget' under the same ID as you're running mrtg.
