Oxidized and Librenms, I don't see the backup of my devices

1

Hello everyone,

I have a problem with Oxidized and LibreNMS. I don’t see the backup of my devices on LibreNMS web interface. Oxidized (web) works well when is alone.
Oxidized and LibreNMS run on fresh install on CentOS 8, installation command :

dnf install curl gnupg2 -y
command curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
command curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -
curl -sSL https://get.rvm.io | bash -s stable
source /etc/profile.d/rvm.sh
rvm requirements
rvm list known
rvm install 2.6.3
rvm use 2.6.3 --default
ruby --version
yum install make cmake which sqlite-devel openssl-devel libssh2-devel ruby gcc ruby-devel libicu-devel gcc-c++
gem install oxidized
gem install oxidized-script oxidized-web

And I have create a oxidized.service in /etc/systemd/system/
I have activated the service and the service start poperly.

I have try to start Oxidized directly on debug mode, when I go to the config tab of a device backed up by Oxidized, I have this errors :

/usr/local/rvm/gems/ruby-2.6.3/wrappers/oxidized --debug

Looks like the problem is with the output of Oxidized configuration. Can you share your configuration?

Yes, I can.

Here my configuration file of Oxidized (I have clear the confidential information) :

username: admin #The (optional) default username on your devices. This can be overridden at group/individual level.
password: ###### #As above, optional default password and can be overridden at group/individual level.
resolve_dns: true #If you provide a hostname, this will DNS lookup the hostname.
interval: 3600 #How often to check for new configs.
use_syslog: true #This option relates to whether you want to use syslog messages to trigger a config fetch.
log: /opt/oxidized/.config/oxidized/logs/
debug: true #Debug mode! Great for setup.
threads: 30
timeout: 60 #Timeout after 20 seconds.
retries: 3 #Try 3 times.
remove_secret: true #Remove secret/enable passwords from the resulting config file - does not work on all models.

utf8_encoded: true

output:
default: git #Output to a Git repository. Oxidized will create the repository based on the settings below.

repo: /opt/oxidized/.config/oxidized/oxidized.git #Where to store the repository
file:
directory: “/opt/oxidized/output/configs” #By default, Oxidized will create a repository for each device.

default: csv
csv:
file: “/opt/oxidized/.config/oxidized/router.db” #File containing all the devices to pull configs from.
delimiter: !ruby/regexp /:confused: #The delimiter for the file. This is the default.
map:
name: 0 #Hostname is the first item in the router.db configuration.
ip: 1 #IP is the second item and so on.
model: 2 #In this case, the router.db would look something like hostname:10.0.0.1:procurve:switches
group: 3 #An arbitrary grouping to keep like devices together.

groups:
switches:
username: login
password: password
firewalls:
username: login
passwords: password
vars:
ssh_port: 22
nexus:
username: login
password: password
wlc:

Thanks

The source is incorrect in your config. Make sure you have all the needed settings.
https://docs.librenms.org/Extensions/Oxidized/

Example source from my server
source:
default: http
debug: true
http:
url: http://127.0.0.1/api/v0/oxidized
map:
name: hostname
model: os
# group: group
headers:

Hello,

Sorry for the delay, I have try and is now working.
I didn’t think he needed it, I wanted to stay with my local file first, that’s okay.

This problem is fixed but I have another problem…

On Oxidized I don’t have all librenms devices, I don’t understand why? Do you have an idea ?

Edit : I managed to remap my Alcatel switches but I don’t know how to detect my WLC?

Thanks
