FreeRADIUS monitoring with Netdata

Uses the radclient command to provide freeradius statistics. It is not recommended to run it every second.

It produces:

1. Authentication counters:

   • access-accepts
   • access-rejects
   • auth-dropped-requests
   • auth-duplicate-requests
   • auth-invalid-requests
   • auth-malformed-requests
   • auth-unknown-types

2. Accounting counters: [optional]

   • accounting-requests
   • accounting-responses
   • acct-dropped-requests
   • acct-duplicate-requests
   • acct-invalid-requests
   • acct-malformed-requests
   • acct-unknown-types

3. Proxy authentication counters: [optional]

   • proxy-access-accepts
   • proxy-access-rejects
   • proxy-auth-dropped-requests
   • proxy-auth-duplicate-requests
   • proxy-auth-invalid-requests
   • proxy-auth-malformed-requests
   • proxy-auth-unknown-types

4. Proxy accounting counters: [optional]

   • proxy-accounting-requests
   • proxy-accounting-responses
   • proxy-acct-dropped-requests
   • proxy-acct-duplicate-requests
   • proxy-acct-invalid-requests
   • proxy-acct-malformed-requests
   • proxy-acct-unknown-typesa

Configuration

Edit the python.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, if different

sudo ./edit-config python.d/freeradius.conf

Sample:

local:

host : 'localhost'

port : '18121'

secret : 'adminsecret'

acct : False # Freeradius accounting statistics.

proxy_auth : False # Freeradius proxy authentication statistics.

proxy_acct : False # Freeradius proxy accounting statistics.

Freeradius server configuration:

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. FreeRADIUS will only respond to status-server messages, if the status-server virtual server has been enabled.

To do this, create a link from the sites-enabled directory to the status file in the sites-available directory:

• cd sites-enabled
• ln -s ../sites-available/status status

and restart/reload your FREERADIUS server.
