I have a 20MB Ethernet circuit and I have set the BANDWIDTH tag to be 20MB. The question I have is this. The 20MB tag sets each way to be 20MB? I can have up to 19MB flowing outbound and it is Red, but I will have 1MB inbound and it is Green. Is the correct way to set the bandwidth to 10MB? or how to I get an overall feeling for how taxed my circuit is using weathermap?
Thanks |

There's two arrows. One for inbound and one for outbound traffic. Look at both of them. Each percentage is calculated seperately.
If you *really* want the whole link (2 arrows) to change colour the same way, then I guess you could do something like:
| Code: |
TARGET myfile.rrd:traffic_in:traffic_out myfile.rrd:traffic_out:traffic_in
|
which will make the 'in' and 'out' values BOTH be the sum of in and outbound traffic, then set the bandwidth to 20M (I guess you mean 10 in + 10 out?).
There's no way to have the percentage be calculated for a half-duplex link though, if that's what you mean... (i.e. in + out = 10M), only full-duplex (10M in+10M out) |
