Luci-app-nlbwmon no data in graphs

[mave37]

Hi, I recently installed luci-app-nlbwmon on my openwrt router. I rebooted the router. I can see the tab and all configuration options in GUI but there is no data in graphs.

Can anyone suggest what may be wrong?

Have you tried "force reload"? There's a link for that, in the screenshot.

[mave37]

yes, I did that. it did nothing. I just did a reset on router. It worked.

Hi everyone, im having the same problem, but i tried to reboot and still nothing!
What else can i check?

Try removing the existing, potentially corrupted, database and restart nlbwmon.

# rm /var/lib/nlbwmon/*.db.gz
# /etc/init.d/nlbwmon restart

I'm having this issue as well. It worked for 1 month, but when a new month started, it wouldn't pick up new data.

I did ssh into openwrt and deleted the database as @slh said above, and that got it back. I suppose at present this needs to be done every month, though. I'd love to know of a way to make it work without that. Or another monitoring package that works.

Thank you, this really helped.

I'm having the issue and and after clearing the file and restart nlbwmon I'm still getting no Traffic error. Any idea as to why?
I have reinstalled the package but still nothing:

It looks like the service is running and has enough memory.

[frollic]

have you already tried Nlbwmon hangs after few days of use ?

I increased the buffer memory and now it's working.
