MRTG Stats

[mns0523]

I have been doing some monitoring of a router for bandwidth utilization. I’m alittle confused on the stats on the bottom of the graphs…..

Max Out 946.2 kB/s (7.6%) <----What is that percent telling me?? Does that mean the max out used 7.6% of my T1?? I have looked around on the MRTG web site and cannot seem to find what these percents represent.

Any help would be great, thanks in advance...

You may want to try this with the MRTG Newsgroup/Mailinglist:

This just means you did not set your MaxBYTES properly, it sounds like you set it to 1.536.000 the T1 speed in BITS. It should be 192.000. Then your 7.6% is exactly right. It should read 8*7.6 = 60.8% Which is much closer to the real value.

I believe that the percentage represents the maximum percentage used of bandwidth. You define the bandwidth in MRTG with the 'MaxBytes' directive for each interface. For a 'raw' T1, the correct Maxbytes value is 193000 (1.544Mbps). For a channelized T1, the correct Maxbytes value is 192000 (1.536Mbps).
