FreeRADIUS monitoring with Netdata

FreeRADIUS is a modular, high performance free RADIUS suite.

This module will monitor one or more FreeRADIUS servers, depending on your configuration.

Requirements

• FreeRADIUS with enabled status feature.

The configuration for the status server is automatically created in the sites-available directory. By default, server is enabled and can be queried from every client.

To enable status feature do the following:

• cd sites-enabled
• ln -s ../sites-available/status status
• restart FreeRADIUS server

Charts

It produces following charts:

• Authentication in pps
• Authentication Responses in pps
• Bad Authentication Requests in pps
• Proxy Authentication in pps
• Proxy Authentication Responses in pps
• Proxy Bad Authentication Requests in pps
• Accounting in pps
• Bad Accounting Requests in pps
• Proxy Accounting in pps
• Proxy Bad Accounting Requests in pps

Configuration

Edit the go.d/freeradius.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/freeradius.conf

Here is an example for 2 servers:

jobs:
  - name: local
    host: 127.0.0.1

  - name: remote
    host: 203.0.113.10
    secret: secret 

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the freeradius collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

First, navigate to your plugins directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/
sudo -u netdata -s

You can now run the go.d.plugin to debug the collector:

./go.d.plugin -d -m freeradius
