[Solved] vnstat -d,-w,-m all return "no data available" but vnstat works.

It has been some time since i checked my bandwidth usage so i don't know if this is because i disabled NetworkManager.service a few weeks ago.
Today when all the above vnstat options returned "no data available" (i've dealt with Not enough data available before), while vnstat without options did throw up some data, i did this:

Code:

:~# systemctl enable vnstat

Synchronizing state of vnstat.service with SysV init with /lib/systemd/systemd-sysv-install...

Executing /lib/systemd/systemd-sysv-install enable vnstat

:~# systemctl start vnstat

:~# pgrep -c vnstatd

1

Still no joy so;

Code:

:~$ sudo vnstat -u -i eth0

and yet;

Code:

:~$ vnstat

Could someone please tell me what's going on here?

No idea but I'd first check what 'vnstat --dumpdb' returns? Should be 89 lines. Then what does 'vnstat --debug -d' return?

I should have remembered to mention i am using OpenDNS servers, sorry; also noticed i don't have the </var/log/vnstat> or </run/vnstat> directories. Added the opendns nameservers in /run/resolvconf/interfaces/eth0 and rebooted, nothing, the files in the DatabaseDir "/var/lib/vnstat/eth0" are unreadable (there's two of them)..seriously, i'm out of my depth here..:cry:

DNS has nothing to do with this, basically vnstat wants to read some /proc and /sys entries for gathering statistics.

Please read the %{application}.conf manual pages: you don't need /var/log/vnstat unless you set the configuration option. And /run/vnstat will be created by systemd's /etc/tmpfiles.d/vnstat.conf or equivalent.

If you mean running 'file' on those files returns "data", yes, that's what the "--dumpdb" arg is for, no need reading the file with an editor or such. Now your version of vnstat may be different than mine, as I said "--dumpdb" returns 89 lines on two completely different Linux distros so I'd say contact the vnstat developer for help, see humdi.net/vnstat/ for contact details.

Thank you for the link, and the commands, already got a reply!
Hi,

was vnStat compiled + installed from the source package or using some
Debian provided (apt-get etc.) binary package?

Your --dumpdb output on the forum looks a little bit corrupted but I'm not
sure if it's due to some copy/paste error or an actual problem in the
database. The fact that the database claims to be created in 1970 at least
suggest something is wrong.

The outputs of the following commands could provide some clues:

1) vnstat --iflist
2) ps aux | grep vnstat
3) ls -la /var/lib/vnstat

-Teemu
To which:

Code:

:~$ vnstat --iflist

Since i last wrote, purged vnstat, force removed the /var/lib/vnstat directory and reinstalled vnstat. That got rid of the "no database available" message but now everything is stuck at 4KiB and i've already downloaded more than 500MB since then.

Purged vnstat once again and installed from source as per http://humdi.net/wiki/vnstat/install/in_debian. Why this works while installing with apt-get did not is beyond me but there it is. It even took care of the locale issue that i used to have before when i had to "LC_ALL=C" for vnstat -d.

Code:

:~$ vnstat -d
