[B.A.T.M.A.N.] Suggestions to get extended jsondoc alfred output

[B.A.T.M.A.N.] Suggestions to get extended jsondoc alfred output

[Germano Massullo]

I created three Fedora virtual machines to get some alfred jsondoc
format output. I followed [1] and [2] but I edited some commands because
virtual machines obviously do not own wireless network interfaces. Since
it is the first time I use batman+alfred I want to show you the entire
list of commands (that have been runned on all the virtual machines.) I
used before asking my question

# ip link set dev enp0s3 mtu 1532
# batctl if add enp0s3
# ip link set bat0 up
# alfred -i enp0s3 -m

The    # ip addr     of all virtual machines is [3]
Then I opened a new console

# cat /etc/hostname | alfred -s 65
# alfred -r 65
then I got [4] as the Examples paragraph [2] suggested
# batadv-vis --format=jsondoc
and I got [5]

Question: do you have any suggestion how I can extend the jsondoc
output, to get an output similar to [6]?

Thank you for your time

Yup this looks good. :)

This looks kind of incomplete - there are no neighbor information at all.

I'd suggest to create a new output type (maybe call it netjson?) next to the 
existing ones. If you look in the source code [1] You'll find a couple of 
hooks which are prepared exactly for this purpose.

Thanks!

I would like to debug this thing. Virtual machines firewall have been
deactivated. I don't understand why
# alfred -r 65
returns a correct output about the three nodes and instead the jsondoc
output only mentions one node...

Thank you, I will check it.

batadv-vis is also a daemon which must run in background to collect data from 
batman-adv and push it (periodically) into alfred. Maybe you are not running 
it but only used the client part to query?

Cheers,

Yeah that was the problem, thank you very much!
I attach again the whole and fixed procedure I followed, hoping that it
can be useful to other people. At the end of the e-mail you can find
also the jsondoc output I got.

1) Install a Fedora VirtualBox virtual machine;
2) In the virtual machine VirtualBox settings, set the network interface
in bridge mode;
3) Clone two times the virtual machine, enabling the "re-initialise MAC
addresses" option;
4) Start them and then run the following commands on each of them:

    Maybe not required, but to avoid all possible problems, I also
disabled the firewall
    # systemctl disable firewalld; systemctl stop firewalld
   
    # dnf -y install batctl
    then download and install alfred from git source code (certain
guides show alfredadv-vis , I instead got batadv-vis)

    # ip link set dev enp0s3 mtu 1532
    # batctl if add enp0s3
    # ip link set bat0 up
    # alfred -i enp0s3 -m

    Then I opened a new console (tty2)
    # cat /etc/hostname | alfred -s 65
    # batadv-vis -s

    Then I opened a new console (tty3)
    # cat /etc/hostname | alfred -s 65
    # alfred -r 65  (note: this one will show the info sent from the
three nodes only if you entered the previous command on all the VMs)
    # batadv-vis --format=jsondoc


And here we go!
