Could it be that the two machines are collecting data at slightly
different times and that although MRTG saw a collection of 122K
the other machine may have seen the collection at say 126K (being
slightly out of sync with the first collection) and so the data
was dropped? You would need to increase the maximum to rule this
out as a possibility.

Subject: [rrd-users] peaks an
I am monitoring a T1 line, mrtg does the data collection for rrdtool.
I still have the old machine running pure MRTG and I see a peak on the T1
at 122.5kBs (98%).
On the test machine I see nothing for the duration of the peak; this is the
definition of the RRD (done by mrtg)
ds[ds0].type = "COUNTER"
ds[ds0].minimal_heartbeat = 600
ds[ds0].min = 0.0000000000e+00
ds[ds0].max = 1.2500000000e+05
ds[ds0].last_ds = "1910596238"
ds[ds0].value = 1.4961330000e+04
ds[ds0].unknown_sec = 0
but this is what a fetch shows as the data:
1016456400: 1.1284171480e+05 9.5934810889e+03
1016456700: 1.1345647667e+05 9.1879496000e+03
1016457000: nan 2.5609493156e+04
1016457300: nan 1.0274055533e+04
1016457600: nan 9.4457169333e+03
1016457900: nan 1.4213377662e+04
1016458200: nan 1.0769259249e+04
I would suspect an out of range value but mrtg reports only 122K while the
max is set at 125K.
Anyone have a clue?
(mrtg is 2.9.12a and rrdtool is 1.0.33)
