Getting NaN in RRD & Graph, EVEN when Poller shows a Value

[bbroge]

Hey all,

I've had this problem about 6 months ago but it eventually somehow just started working back then after 100 computer restarts and browsing around, I never figured out what I changed that would have fixed the issue. Now that I created a new graph it is happening again, although all my old graphs are still working just fine! I've been through the RRD troubleshooting sections thousands of times and is the only reason I'm requesting help at this point. I also found a post of someone having a similar problem as me (viewtopic.php?f=2&t=48441) However my poller settings are all default 5 minutes and as you can see my rrd file is set for the normal step and heartbeat. Please, does anyone have any ideas?

I'm on Version 1.1.15 (and would be willing to update) if that might fix the issue. Im using Ubuntu server 16.

I am certain all my rrd files are being updated correctly however when running rrdtool fetch average:

---ommited---
506635700: -nan
1506636000: -nan
1506636300: -nan
1506636600: -nan
1506636900: -nan
1506637200: -nan
1506637500: -nan
1506637800: -nan
1506638100: -nan
1506638400: -nan

rrdtool info shows last_ds and value getting updated with correct value:
filename = "hashrate_bbroge_14.rrd"
rrd_version = "0003"
step = 300
last_update = 1506656101
header_size = 3704
ds[antminerd].index = 0
ds[antminerd].type = "GAUGE"
ds[antminerd].minimal_heartbeat = 600
ds[antminerd].min = 0.0000000000e+00
ds[antminerd].max = 1.0000000000e+05
ds[antminerd].last_ds = "17203.39"
ds[antminerd].value = 1.7203390000e+04
ds[antminerd].unknown_sec = 0
rra[0].cf = "AVERAGE"

I also want to add the I don't see anytihng out of the ordinary in the logs when debugging is eanbled. When I go to my data source I see all this great data being populated, and even though my rrd file is updated, I'm still getting nans in the graphs ( as well as nans with fetch average command in rrd file)?

It appears to be working now, maybe I just need to be more patient.
