[rrd-users] values get updated in RRD DB but doesnt reflect when doing a fetch or dump

[Alex van den Bogaerdt]

Your updates do not make it into the RRD. They are filtered out. 
Wether you know it or not, you are asking RRDtool to ignore those updates.
Updates further apart than the heartbeat, are assumed to be unreliable and result in unknown data.
Your heartbeat is 2000.  Your updates are 3600 apart.

  Subject: [rrd-users] values get updated in RRD DB but doesnt reflect when doing a fetch or dump





  i am populating an rrd db once an hour. The value gets successfully updated in rrd db but it doesnt doesnt get updated to archives 
  Whenever i try to fetch data using rrdfetch it return NaN and rrddump showns dump too.

  but rrdtool info shows the last update value .

  steps is 2000 and rras





'RRA:MIN:0.5:1:44640'
'RRA:MAX:0.5:1:44640'
'RRA:AVERAGE:0.5:1:44640'
'RRA:LAST:0.1:1:44640'

Following is my rrdtool info output .

filename = "abc.red.prod.rrd"
rrd_version = "0003"

last_update = 1341392733
ds[resume_l].type = "GAUGE"
ds[resume_l].minimal_heartbeat = 2000
ds[resume_l].min = NaN
ds[resume_l].max = NaN

    rra[0].cf = "MIN"
    rra[0].rows = 44640
    rra[0].cur_row = 31110
    rra[0].pdp_per_row = 1
    rra[0].xff = 5.0000000000e-01
    rra[0].cdp_prep[0].value = NaN
    rra[0].cdp_prep[0].unknown_datapoints = 0
    rra[0].cdp_prep[1].value = NaN
    rra[0].cdp_prep[1].unknown_datapoints = 0
    rra[1].cf = "MAX"
    rra[1].rows = 44640
    rra[1].cur_row = 32625
    rra[1].pdp_per_row = 1
    rra[1].xff = 5.0000000000e-01
    rra[1].cdp_prep[0].value = NaN
    rra[1].cdp_prep[0].unknown_datapoints = 0
    rra[1].cdp_prep[1].value = NaN
    rra[1].cdp_prep[1].unknown_datapoints = 0
    rra[2].cf = "AVERAGE"
    rra[2].rows = 44640
    rra[2].cur_row = 41634
    rra[2].pdp_per_row = 1
    rra[2].xff = 5.0000000000e-01
    rra[2].cdp_prep[0].value = NaN
    rra[2].cdp_prep[0].unknown_datapoints = 0
    rra[2].cdp_prep[1].value = NaN
    rra[2].cdp_prep[1].unknown_datapoints = 0
    rra[3].cf = "LAST"
    rra[3].rows = 44640
    rra[3].cur_row = 8075
    rra[3].pdp_per_row = 1
    rra[3].xff = 1.0000000000e-01
    rra[3].cdp_prep[0].value = NaN
    rra[3].cdp_prep[0].unknown_datapoints = 0
    rra[3].cdp_prep[1].value = NaN
    rra[3].cdp_prep[1].unknown_datapoints = 0


and this is the output of rrdtool dump .. only selected regions
