oops, you shouldn't change this file under any circumstances. Can you <br>
reset this file using "git checkout"?<br>
<br>
Any customisation you might need to make can be handled in .env.<br>

<br>
You should use "rrdtool dump p2p.ipv4.bytes.src-00001.dst-00003.rrd" to <br>
ensure that sflow is reading the data correctly.<br>

<br>
The "dummy" / "no image found" are only for mrtg, not sflow.<br>

<br>
no, it means that the Grapher back-end uses both mrtg and sflow. These <br>
are separate things: the MRTG grapher produces interface graphs and the <br>
sflow grapher produces point-to-point graphs.<br>

<br>
yes, you need to install mrtg if you want regular interface graphs.<br>
