Using different versions of rrdtool on windows 7 x64 platform, I faced this and
I cannot understand the reason : the max or current printed values does not
always
match updated data :
Lets take an example :
creating the db file :
rrdtool.exe create temp.rrdtool-db -b 1501538399
DS:SERIE:GAUGE:86400:U:U
RRA:LAST:0.5:288:10
updating data :
rrdtool.exe update temp.rrdtool-db -t SERIE 1501624799:0 1501711199:0
1501797599:0
1501883999:0 1501970399:0 1502056799:0 1502143199:0 1502229599:0
1502315999:176
graphing :
rrdtool.exe graph Change.png -a PNG --start 1501538399 -F --step 300 -l 0
-h 200 -v "Count" -w 800 -r -b 1000
DEF:DS=temp.rrdtool-db:SERIE:LAST
AREA:DS#0000FF:"Change"
GPRINT:DS:MAX:" Max \: %10.0lf "
GPRINT:DS:LAST:" Current \: %10.0lf \n"
The graph is generated. Looking at graph, the Current and max vals are 175
(should be 176)
new one :
creating the db file :
rrdtool.exe create temp.rrdtool-db -b 1501538399
DS:SERIE:GAUGE:86400:U:U
RRA:LAST:0.5:288:10
updating data :

1502315999:176
1502402399:1495
graphing :
rrdtool.exe graph Change.png -a PNG --start 1501538399 -F --step 300 -l 0
-h 200 -v "Count" -w 800 -r -b 1000
DEF:DS=temp.rrdtool-db:SERIE:LAST
AREA:DS#0000FF:"Change"
GPRINT:DS:MAX:" Max \: %10.0lf "
GPRINT:DS:LAST:" Current \: %10.0lf \n"
The graph is generated. Looking at graph, the Current and max vals are 1490
. (should be 1495)
Where am I wrong ? What did I wrong ???
Thanks for your lights, I am clueless
Cheers
