This is going to sound trivial, but is there any way to get the UI to show the date in the UK format. I.E. 7/3/21 (7th March 21) instead of the US method 3/7/21.

Thanks for your hard work.

Explained a few posts above yours.

Thanks for your hard work.

DayFormat "%d/%m/%y"
MonthFormat "%b '%y"
TopFormat "%d/%m/%y"
 
Thank you. I guess I missed that!
 
DayFormat "%d/%m/%y"
MonthFormat "%b '%y"
TopFormat "%d/%m/%y"
I edited vnstat.conf according to this ... but I am still getting the old date format after hard refreshing.

Something more to edit?

Ha! I was just about to post the exact same, screen shots too!

I have tried rebooting the router and control-F5
 
Have you tried to manually generate new images/generate stats?
 
Yes I have. Interesting, the CLI does show the correct UK format. But the GUI still shows the US format.

According to MAN DATE, the format is %d-%b-%Y for dd-MMM-YYYY.

And once you've edited the conf file, do a "1" update and then a hard refresh.

For clarity, new installs will include the MMM (month) in the date format. We're a supportive bunch!

EDIT: just tested and it works in the UI (%d-%b-%Y).

Thank you, It worked fine.

Editing ...
# date output formats for -d, -m, -t and -w
# see 'man date' for control codes
DayFormat "%d-%b-%Y"
MonthFormat "%b '%y"
TopFormat "%d-%b-%Y"

I also edited
# title timestamp format
HeaderFormat "%d-%b-%Y %H:%M"
In order to get the yellow date and time according to that.
 
Strange. Try a reboot. It's working perfectly here
Ah. I added the lines:

# title timestamp format
HeaderFormat "%d-%b-%Y %H:%M"

Now all is well. Thanks figorr for the suggestion.

Thanks all.
 
I’m new to command lines, but how can I make the log save to the USB drive instead of memory on the router? I only have 1 USB drive connected.

Hello there. What is this error and how can I fix it? Tell me please.

The default location for the database files is /opt/var/lib/vnstat/ which is actually symlinked to /mnt/your_usb_drive/entware/var/lib/vnstat/. So the dbs are on your usb drive already.

Weird Numbers, any way to "reset" them?
Hmmm, never saw this in any of the testing, except a "doubling" on one import on one test. I'd suggest backing up your db: vnstat --exportdb > /path/to/vnstat-export-db.txt before taking any additional steps.

Can you post or PM what was happening around the time of this discovery and describe your hardware/firmware version, please.

Before you reset, can you run /jffs/scripts/dn-vnstat generatestats and then PM the output of /tmp/vnstat.txt please, and run vnstat -h (hours) and PM me that too, please?

Then you can reset the database by running vnstat -r (or vnstat --reset).

This looks like a missing application/dependency (for the imagemagick component). Can you describe the device and firmware version please. You may also try to re-run the CLI full install command (it won't delete any data files) to see if that helps.

Device ASUS RT-AX88U firmware Asus Merlin 386.1_2. Re-installing the CLI did not give a result. Deleted opkg remove imagemagick --autoremove, opkg remove vnstat --autoremove, opkg remove vnstati --autoremove rebooted the device and installed it in a new way did not help. Another error when generating statistics via amtm in the screenshot.
convert: UnableToLoadModule '/tmp/mnt/app/entware/lib/ImageMagick-7.0.9/modules-Q8/coders/png.la': file not found @ error/module.c/OpenModule/1287.

See, posts 24, 25 & 34 For issue I had and Jack Yaz response to a log I sent him. Other than reinstalling back then (I think 3/3 or 3/4), when I upgraded to AMTM, there was an upgrade in amtm to 0.9.4 even though I was already on 0.9.4, but I said update anyhow (through amtm).

I will attempt to get the info you asked for and get back to you through posts here or PM (depending on how long the data is when I run it --I'll try now, hopefully I can get it).

Edit: RT-AC86U 386.1_2
