[Xymon] Which RRD data type?

[Ward, Martin]

Hi all,

I have successfully created a new graph in Xymon 4.2.2 but the RRD data type seems to be wrong.

I have a file that I am counting certain records out of and this file is reset every night, so at 00:00 I will have zero records and by 23:59 I will have a few hundreds of thousands. I would like to have this graphed such that I can see the difference in each 5 minute interval. That is if the value is 105 at 02:30 and 115 at 02:35 I want the graph to show 10. I thought that using the DERIVE data type would suffice but it's not working, the graphs are showing 5-minutes values of around 5 or ten when in fact they should be measured in the thousands.

Looking at the stored data shows the archive values as very small numbers:
                        <!-- 2011-10-15 14:05:00 UTC / 1318687500 --> <row><v> 3.1877856295e+00 </v><v> 1.1824717464e-02 </v><v> 4.5896234412e-03 </v></row>
                        <!-- 2011-10-15 14:10:00 UTC / 1318687800 --> <row><v> 3.7026029130e+00 </v><v> 1.2536687862e-02 </v><v> 5.3445468747e-03 </v></row>
                        <!-- 2011-10-15 14:15:00 UTC / 1318688100 --> <row><v> 2.4754966887e+00 </v><v> 1.5286975717e-02 </v><v> 7.1192052980e-03 </v></row>
                        <!-- 2011-10-15 14:20:00 UTC / 1318688400 --> <row><v> 1.8862367114e+00 </v><v> 2.1885456605e-02 </v><v> 1.6929316254e-02 </v></row>

Yet the Xymon page shows the latest values thus:

Monday October 17 14:02:35 UTC 2011

LoginFailures:   300384
Sources:     2518
Targets:     3096

(these values are after 14 hours of data collection).

How can I graph the 5-minute difference for this data and have it actually display the data I want?
