Hi Michel - I suspect yours are embedded because your using the RRD
backend and rrd_graph creates the stats. The the mrtg logfile backend,
IXP Manager has to calculate the stats.<br>

<br>Hi Michel,
<br>
<br><br>
<br>While you're correct that the graph images are generated at
different
times, the table of values is generated in real-time by IXP Manager and
when presented on the same page as the screenshot given, with the single
read of the mrtg log/rrd data.
<br>
<br>I.e. all good here.
<br>
<br>I know some mrtg frontend's embed the values in the graph image but
that's not happening here.
<br>
<br> - Barry

Mauricio,<div><br></div><div>I have no knowledge of how IXP Manager

that last comment a further thought, your “day” and “week” graphs are
missing the “max” values. You only show the average values, whereas your
month and year graphs do show maximums. These are your pink and dark
green lines on the graph - the light green and blue lines are your
averages, typically over 5 min if you haven’t changed anything.</div><div><br></div><div>Hence,
the “max” values could very well be correct, and they match what is
displayed in the month/year graphs, but this information is not visible
in the day and week graphs.</div><div><br></div><div>Which leaves still
the “current” values somehow odd as being exactly identical on all
graphs… have you played with the commands/parameters to generate the
