Integrate with Observium

Support level: Community

What is Observium?​

Observium is a network monitoring and management platform that provides real-time insight into network health and performance.

-- https://observium.org

Preparation​

The following placeholders are used in this guide:

  • observium.company is the FQDN of the Observium installation.
  • authentik.company is the FQDN of the authentik installation.
info

This documentation lists only the settings that you need to change from their default values. Be aware that any changes other than those explicitly mentioned in this guide could cause issues accessing your application.

Observium does not have a native OpenID Connect integration, so this guide uses mod_auth_openidc to authenticate users with authentik and pass them to Observium through Apache REMOTE_USER authentication. This guide assumes that you already have a working Observium instance served by Apache HTTP Server with mod_auth_openidc installed and enabled.

authentik configuration​

Redirect URI changes in authentik 2026.5

In authentik versions earlier than 2026.5, all Redirect URIs are automatically treated as Authorization type. If you are using one of these older authentik versions, add only the Authorization URL to your Redirect URIs and do not configure a Post Logout URI.

To support the integration of Observium with authentik, you need to create an application/provider pair in authentik.

Create an application and provider in authentik​

  1. Log in to authentik as an administrator and open the authentik Admin interface.

  2. Navigate to Applications > Applications and click New Application to open the application wizard.

    • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings. Take note of the Slug value because it will be required later.
    • Choose a Provider type: select OAuth2/OpenID Connect as the provider type.
    • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
      • Note the Client ID and Client Secret values because they will be required later.
      • Add a Redirect URI of type Strict Authorization as https://observium.company/secure/redirect_uri. Note that the Redirect URI can be anything, as long as it does not point to existing content.
      • Select any available signing key.
    • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's Application Dashboard page.

  3. Click Submit to save the new application and provider.

Observium configuration​

  1. Edit the Apache virtual host that serves Observium and add the following directives inside the <VirtualHost> block:

    /etc/apache2/sites-available/000-default.conf
    <VirtualHost *:80>
        # Existing Observium configuration

        OIDCProviderMetadataURL https://authentik.company/application/o/<application_slug>/.well-known/openid-configuration
        OIDCClientID <Client ID from authentik>
        OIDCClientSecret <Client Secret from authentik>
        OIDCRedirectURI https://observium.company/secure/redirect_uri
        OIDCCryptoPassphrase <random string>
        OIDCScope "openid email profile"
        OIDCRemoteUserClaim preferred_username ^(.*)$ $1@authentik

        <Location />
            AuthType openid-connect
            Require valid-user
        </Location>
    </VirtualHost>

    If Observium is behind a reverse proxy that sends X-Forwarded-* headers, also configure OIDCXForwardedHeaders with every forwarded header that reaches Apache, for example:

    OIDCXForwardedHeaders X-Forwarded-Host X-Forwarded-Proto X-Forwarded-Port

  2. Edit the Observium configuration:

    /opt/observium/config.php
    $config['auth_mechanism'] = "remote";
    $config['auth_remote_userlevel'] = 10;
    $config['auth_remote_logout_url'] = "https://authentik.company/application/o/<application_slug>/end-session/";

    With this method, Observium assigns the same permission level to all remotely authenticated users. The value 10 gives users administrator access. Choose the user level that fits your Observium access policy.

  3. Restart the Apache2 service:

    service apache2 restart

Configuration verification​

To confirm that authentik is properly configured with Observium, open Observium. You should be redirected to authentik and, after a successful login, returned to Observium.
