[Xymon] Able to generate RRD but graphs do not show up

Hi all,

I have a check in xymon to plot the time taken for several reports on the
system to be run. For each report, I have xymon monitors that are
collecting the data to the rrds but I am unable to populate the graph for
these checks.

Below is the output of rrdtool <info> on one of the rrds -

filename = "SecondsElapsed.rrd"
rrd_version = "0003"
step = 300
last_update = 1446514863
header_size = 1216
ds[SecondsElapsed].index = 0
ds[SecondsElapsed].type = "GAUGE"
ds[SecondsElapsed].minimal_heartbeat = 900
ds[SecondsElapsed].min = 0.0000000000e+00
ds[SecondsElapsed].max = NaN
ds[SecondsElapsed].last_ds = "5"
ds[SecondsElapsed].value = NaN
ds[SecondsElapsed].unknown_sec = 63
rra[0].cf = "AVERAGE"
rra[0].rows = 576
rra[0].cur_row = 258
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[1].cf = "AVERAGE"
rra[1].rows = 576
rra[1].cur_row = 481
rra[1].pdp_per_row = 6
rra[1].xff = 5.0000000000e-01
rra[1].cdp_prep[0].value = 0.0000000000e+00
rra[1].cdp_prep[0].unknown_datapoints = 2
rra[2].cf = "AVERAGE"
rra[2].rows = 576
rra[2].cur_row = 382
rra[2].pdp_per_row = 24
rra[2].xff = 5.0000000000e-01
rra[2].cdp_prep[0].value = 0.0000000000e+00
rra[2].cdp_prep[0].unknown_datapoints = 20
rra[3].cf = "AVERAGE"
rra[3].rows = 576
rra[3].cur_row = 338
rra[3].pdp_per_row = 288
rra[3].xff = 5.0000000000e-01
rra[3].cdp_prep[0].value = 0.0000000000e+00
rra[3].cdp_prep[0].unknown_datapoints = 20

Below is my graph definition in graphs.cfg (The column name in Xymon is
"Status")

[Status]
        FNPATTERN SecondsElapsed.rrd
        TITLE Report Execution time in seconds
        YAXIS Seconds
        DEF:SecondsElapsed=SecondsElapsed.rrd:SecondsElapsed:AVERAGE
        GPRINT:SecondsElapsed:LAST:Minutes\: %5.0lf (cur)

Any clues why my graphs are not working ? Thanks!

Regards,
Raunak
