Ralph M <user-00a5e44c48c0@xymon.invalid> a ?crit :
Gaps like that happen when there's missing data. There's not a lot
you can do about that.
i think that to (and Jeremy Laidman previous answer)
If you really, really want to make the gaps go away, you can try
dumping out the RRD to XML, edit the dump, then load it back in.
rrdtool dump xymon.rrd
$ rrdtool dump "${RRDBASEHOST}/ups,BCHARGE.rrd" | tail -7 | sed
's#.*-->\(.*\)# \1#'
<row><v>9.9378222222e+01</v></row>
<row><v>NaN</v></row>
<row><v>1.0000000000e+02</v></row>
<row><v>1.0000000000e+02</v></row>
</database>
</rra>
</rrd>
I'll try to see the trouble, and after trying to add "missing data with
value not too bad"
