Oxidized intro

---

Integrating LibreNMS with Oxidized brings the following benefits:

• Config viewing: Current, History, and Diffs all under the Configs tab of each device
• Automatic addition of devices to Oxidized: Including filtering and grouping to ease credential management
• Configuration searching (Requires oxidized-web 0.8.0 or newer)

First you will need to install Oxidized following their documentation.

Then you can procede to the LibreNMS Web UI and go to Oxidized Settings in the External Settings section of Global Settings. Enable it and enter the url to your oxidized instance.

To have devices automatically added, you will need to configure oxidized to pull them from LibreNMS Feeding Oxidized

Detailed integration information

---

This is a straight forward use of Oxidized, it relies on you having a working Oxidized setup which is already taking config snapshots for your devices. When you have that, you only need the following config to enable the display of device configs within the device page itself:

$config['oxidized']['enabled']         = TRUE;
$config['oxidized']['url']             = 'http://127.0.0.1:8888';

LibreNMS supports config versioning if Oxidized does. This is known to work with the git output module.

$config['oxidized']['features']['versioning'] = true;

Oxidized supports various ways to utilise credentials to login to devices, you can specify global username/password within Oxidized, Group level username/password or per device. LibreNMS currently supports sending groups back to Oxidized so that you can then define group credentials within Oxidized. To enable this support please switch on 'Enable the return of groups to Oxidized':

$config['oxidized']['group_support'] = true;

You can set a default group that devices will fall back to with:

$config['oxidized']['default_group'] = 'default';

SELinux

If you're runnng SELinux, you'll need to allow httpd to connect outbound to the network, otherwise Oxidized integration in the web UI will silently fail:

setsebool -P httpd_can_network_connect 1

Feeding Oxidized

---

Oxidized has support for feeding devices into it via an API call, support for Oxidized has been added to the LibreNMS API. A sample config for Oxidized is provided below.

You will need to configure default credentials for your devices in the Oxidized config, LibreNMS doesn't provide login credentials at this time.

      source:
        default: http
        debug: false
        http:
          url: https://librenms/api/v0/oxidized
          map:
            name: hostname
            model: os
            group: group
          headers:
            X-Auth-Token: '01582bf94c03104ecb7953dsadsadwed'

LibreNMS is able to reload the Oxidized list of nodes, each time a device is added to LibreNMS. To do so, edit the option in Global Settings>External Settings>Oxidized Integration or add the following to your config.php.

$config['oxidized']['reload_nodes'] = true;

Working with groups

To return a group to Oxidized you can do this by matching a regex for either hostname, sysname, os or location. The order is hostname is matched first, if nothing is found then sysname is tried, then os, and finally location is attempted. The first match found will be used. To match on the device hostnames or sysnames that contain 'lon-sw' or if the location contains 'London' then you would place the following within config.php:

$config['oxidized']['group']['hostname'][] = array('regex' => '/^lon-sw/', 'group' => 'london-switches');
$config['oxidized']['group']['sysname'][] = array('regex' => '/^lon-sw/', 'group' => 'london-switches');
$config['oxidized']['group']['location'][] = array('regex' => '/london/', 'group' => 'london-switches');

To match on a device os of edgeos then please use the following:

$config['oxidized']['group']['os'][] = array('match' => 'edgeos', 'group' => 'wireless');

Verify the return of groups by querying the API:

curl -H 'X-Auth-Token: YOURAPITOKENHERE' https://librenms.org/api/v0/oxidized				

If you need to, you can specify credentials for groups by using the following in your Oxidized config:

groups:
  <groupname>:
    username: <user>
    password: <password>

Miscellaneous

If you have devices which you do not wish to appear in Oxidized then you can edit those devices in Device -> Edit -> Misc and enable "Exclude from Oxidized?"

It's also possible to exclude certain device types and OS' from being output via the API. This is currently only possible via config.php:

$config['oxidized']['ignore_types'] = array('server');
$config['oxidized']['ignore_os'] = array('linux');

Trigger configuration backups

Using the Oxidized REST API and Syslog Hooks, Oxidized can trigger configuration downloads whenever a configuration change event has been logged. An example script to do this is included in ./scripts/syslog-notify-oxidized.php. Oxidized can spawn a new worker thread and perform the download immediately with the following configuration

next_adds_job: true
