Hi,
I am a new nfdump/nfsen user however I believe I have configured my system
correctly by cross-referencing several guides online.
I am encountering an issue whereby I can receive sFlow data using sfcapd which
is being logged correctly in /data/nfsen/profiles-data/live/* however the .rrd
file in /data/nfsen/profiles-stat/live* fails to update. It's file size never
increases and is filled with 'NaN' values when I look at it using `rrdtool
dump`.
As a result, I can view tabular data via nfdump when viewing nfsen but my
graphs, driven by rrd, are all empty. I have tested the process on Ubuntu 16.04
and 18.04 and see the exact same issue on both versions. Both nfdump and nfsen
were built from source.
I cannot see any obvious indications that nfsen is having issues accessing the
rrd file so would be grateful for assitance to figure out where the problem
lies.
Thanks,
Mark
