The problem related to graphs with 20 minutes interval is in the creation of the rrd file
From the rrdcreate help page http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html
DS:ds-name:GAUGE | COUNTER | DERIVE | ABSOLUTE:heartbeat:min:maxThe heartbeat'' defines the maximum acceptable interval between samples. If the interval between samples is less than heartbeat'',
then an average rate is calculated and applied for that interval. If the
interval between samples is longer than heartbeat'', then that entire interval is considered unknown''. Note that there are other things
that can make a sample interval unknown'', such as the rate exceeding limits, or even an unknown'' input sample.
The heartbeat used by hobbit for ncv (and other graphs) is 600 (10 min) and cannot be changed with parameters so you need to change the source code (but it will change heartbeat for all the NCV graphs you do and you've to remember to change it when installing a new version) or we have to wait for Henrik to do a new rrd extendible interface for all our special graphs cases :D If you need to change you've to change it in the hobbitd/rrd/do_ncv.c, search for "DS:", you'll find 2 of them they are for the default and not default cases of ncv file creation. I don't know if there's something else that need to be changed but this should at least get your data inside the rrd file.

Thanks Henrick, now it work
I have another problem .... sometimes the rrd graphs lost values I send data to hobbit server every 20 minutes ... i must change or add something in hobbitgraph definitions?

The rrd will get MySQLConnectionstat as the name of the first data to save in the rrd instead of getting Threads.
This patch should fix it.

Hi Enrick,
you think may be usefull to have the possibity to customize the interval in the creation of the rrd file from NCV directive? I have a lot of custom graphs on clent data that are sending beyond this intervall :-(
