[rrd-users] RRD smoothing - please help

[johan thoren]

Here is the RRD info. Look specifically at rra[0].cdp_prep[1].value = 2.2500000000e+00
Im possitive that Im only sending integer values to RRD. And them are sent every 100 seconds. 
 
filename = "99.rrd"
rrd_version = "0003"
step = 100
last_update = 1226319614
ds[sPHI].type = "GAUGE"
ds[sPHI].minimal_heartbeat = 100
ds[sPHI].min = 0.0000000000e+00
ds[sPHI].max = 1.8760000000e+03
ds[sPHI].last_ds = "UNKN"
ds[sPHI].value = 0.0000000000e+00
ds[sPHI].unknown_sec = 0
ds[sPHO].type = "GAUGE"
ds[sPHO].minimal_heartbeat = 100
ds[sPHO].min = 0.0000000000e+00
ds[sPHO].max = 1.8760000000e+03
ds[sPHO].last_ds = "UNKN"
ds[sPHO].value = 4.2000000000e+01
ds[sPHO].unknown_sec = 0
ds[sARI].type = "GAUGE"
ds[sARI].minimal_heartbeat = 100
ds[sARI].min = 0.0000000000e+00
ds[sARI].max = 1.8760000000e+03
ds[sARI].last_ds = "UNKN"
ds[sARI].value = 0.0000000000e+00
ds[sARI].unknown_sec = 0
ds[sARO].type = "GAUGE"
ds[sARO].minimal_heartbeat = 100
ds[sARO].min = 0.0000000000e+00
ds[sARO].max = 1.8760000000e+03
ds[sARO].last_ds = "UNKN"
ds[sARO].value = 0.0000000000e+00
ds[sARO].unknown_sec = 0
rra[0].cf = "MAX"
rra[0].rows = 1000
rra[0].pdp_per_row = 3
rra[0].xff = 0.0000000000e+00
rra[0].cdp_prep[0].value = 0.0000000000e+00
rra[0].cdp_prep[0].unknown_datapoints = 0
rra[0].cdp_prep[1].value = 2.2500000000e+00
rra[0].cdp_prep[1].unknown_datapoints = 0
rra[0].cdp_prep[2].value = 0.0000000000e+00
rra[0].cdp_prep[2].unknown_datapoints = 0
rra[0].cdp_prep[3].value = 0.0000000000e+00
rra[0].cdp_prep[3].unknown_datapoints = 0

Thanks
Johan

Hej Johan,

If you'd like to get rid of any double X.XX values and convert them to 
integers, have you considered a Perl or C or Bash or ZSH int/floor/ceil 
type of function? :-)  Perhaps there's some intermediate steps that could 
also happen between the data returned by rrdtool and your application? 
It should be rather trivial to convert all those mathematical values? :-)

With regards to your previous email (as you write -- "my goal is to store 
data and ONLY display the maximum value"), max values are not necessarily 
integer values.  Are you also able to share more about your overall goals?

As a disclaimer, I'm sure there's others on this mailing list that know
a 
lot more than I do about such things, and I defer to their wise expertise.

Hope this may help, at least a bit.   Take care,
