[mrtg] 14all.cgi and too high graph.

[Peter Baumann]

Hello MRTG List

Maybe someone can help me.
I have a strange behavior of 14all.cgi and the data entered in the router.rrd file. Today a customer had an break of his line and I couldn't monitor his router anymore. He have a 128 Kbps line and in the rrd-file I have a limitation setup of 128 Kbps
->
                <name> ds0 </name>
                <type> COUNTER </type>
                <minimal_heartbeat> 86400 </minimal_heartbeat>
                <min> NaN </min>
                <max> 1.2800000000e+05 </max>

Now today at 13:25:00 I had a "normal" traffic value. and at 13:30 the values where right limited (100Kbps). Now my questions:

- Why is it not going to exactly 128Kbps as specified in the rrd file.
- Why is 14all.cgi script displaying a 800Kbps ! peak (rectangle block) in the browser.

I had this behavior many times and I think somewhere is a bug in 14all.cgi. Maybe someone have the same kind of problems ???

Here's a cut of the rrd-file I translated into xml. this part is the time between 13:25 and 13:50.
