Hi Alex, Thank you.
I have changed to database with type DERIVE in stead of COUNTER with
"rrdtool tune " and I have not had problems, but when a data is insert
automatically into the data base (.rrd) happens that the type is counter
again automatically
#./rrdtool tune demoing.rrd
DS[ds0] typ: COUNTER hbt: 600 min: 0.0000 max:
12500000.0000
DS[ds1] typ: COUNTER hbt: 600 min: 0.0000 max:
12500000.0000
change the type with
# ./rrdtool tune demoing.rrd --data-source-type ds0:DERIVE
# ./rrdtool tune demoing.rrd --data-source-type ds1:DERIVE
# ./rrdtool tune demoing.rrd
DS[ds0] typ: DERIVE hbt: 600 min: 0.0000 max:
12500000.0000
DS[ds1] typ: DERIVE hbt: 600 min: 0.0000 max:
12500000.0000
insert a data and ....
#./rrdtool tune demoing.rrd
DS[ds0] typ: COUNTER hbt: 600 min: 0.0000 max:
12500000.0000
DS[ds1] typ: COUNTER hbt: 600 min: 0.0000 max:
12500000.0000
Same idea to force the type to Derive.
Thanks you very much.
