Got 400 - Bad Request. rrd_xport failed. unknown option '--json'

Hi.

I got this error when open the frontend

Got 400 - Bad Request. rrd_xport failed. unknown option '--json'

I already make sure the rrdtool that I installed on server is latest version.

Can you help me

What's your exact rrdtool version?

[oishiiLatte]

ver 1.7.0

[mbolli]

Hey, can you check if you have libxml2 installed? Should be covered by librrd-dev's dependencies, but you never know...
Generally the --json option was introduced with rrdtool 1.4.6 at the beginning of 2012 – are you sure it actually uses version 1.7.0?

I'm having the same issues. Brand new 18.04.2 LTS install.

Trying to answer most of your questions in this issue and the previous one (#17):

nfsen installed with 'git clone https://github.com/mbolli/nfsen-ng' today, nfdump 1.6.17 compiled with '--enable-nfprofile' yesterday. Same error on the page when loading /nfsen-ng/frontend/ :

Got 400 - Bad Request. rrd_xport failed. opening '/var/www/html/nfsenng/backend/datasources/data/source1.rrd': No such file or directory

Changing to LOG_DEBUG in settings.php doesn't give any extra information in syslog or apache access/error logs. This is what the request and the 400 error look like in apache log:

And this is what I see in syslog:

Can you post a listing of /var/www/html/nfsen-ng/backend/datasources/data/?

[crognlie]

There is no data subdir:

`/var/www/html/nfsen-ng$ ls backend/datasources/

akumuli.php datasource.php rrd.php`

Hi,

It seems that no import has been done before starting the daemon. My suggestion is to import the data first. Can you reboot the machine and try a complete import before to start the daemon ?

Locate the directory where cli.php is located and cd there :
cd /var/www/html/nfsen-ng/backend

As root, run the import command
./cli.php -f -p -ps import

Hi Hossein,

Let's try to find out where that could come from ;)

• Did you edit your copy of settings.php ?
• Do you have some nfcapd data under /var/nfdump/profiles-data/live ? There is a note in the configuration part of the README concerning the expected profiles-data folder structure -> PROFILES_DATA_PATH/PROFILE/SOURCE/YYYY/MM/DD/nfcapd.YYYYMMDDHHII, e.g. /var/nfdump/profiles_data/live/source1/2018/12/01/nfcapd.201812010225
• In case you have the data mentioned on the previous point, do you execute the daemon command with a user that has the correct read permissions for /var/nfdump/profiles-data/live directory, sub directories and files ?

Please note that your issue seems not to be related with this closed one, opening another one would be better.

Thanks and regards
