Bandwidth Graphs are empty, Bandwidth Data has query failed?

[victorhooi]

Hi,

I reset my router to the default configurations, then went to download the bandwidth usage.

It's still the same error message, even with nothing configured yet:

Code: Select all

ERROR: Bandwidth query failed, make sure rule with specified id exists, and that you are performing only one query at a time.

I SSH-ed to the box, and under /tmp/data/bwmon, I have a three files which seem nearly empty:

bdist1-upload-minute-15.bw
bdist2-upload-900-24.bw
bdist3-upload-hour-24.bw

Each file contains only the text:

Code: Select all

^@^@^@^@

Are these files meant to contain something?

Cheers,
Victor
