Hi Jason,
>From experience, a shadow profile will not create/copy any actual data
files, but rather rely on the files upon which the profile is generated
(i.e. 'live'.) If you're somehow copying/cloning an existing profile, you
need also make sure that your 'profiles-data' directory structure is in
sync with what's defined in 'profiles-stat', else your graphs will be
blank. Same as with any tinkering in the 'profile.dat' -- If directories do
not match channel data, no graphs (ask me how I know... ;) )
My initial thought, though, is that file permissions might be at play. Your
flows/packets/traffic graphs (in 'profiles-stat') should be generated every
cycle, along with update to any RRD files. If they aren't, make sure the
nfsen daemon is running and that file permissions are set appropriately.
If you want to check that 'nfprofile' knows where to find all its
libraries, use 'ldd': Any 'not found' messages mean you need to set
'LD_LIBRARY_PATH' or maybe run 'ldconfig'.
Ex:
ldd /opt/netflow/bin/nfprofile
linux-vdso.so.1 => (0x00007fff783fe000)
librrd.so.4 => /usr/lib64/librrd.so.4 (0x00007fbbc28e1000)
libresolv.so.2 => /lib64/libresolv.so.2 (0x00007fbbc26c7000)
~
Obviously, you'd use whatever path to 'nfprofile' is relevant to your
installation.
Cheers!
