FreeRADIUS

The FreeRADIUS application extension requires that status_server be enabled in your FreeRADIUS config. For more information see: https://wiki.freeradius.org/config/Status

You should note that status requests increment the FreeRADIUS request stats. So LibreNMS polls will ultimately be reflected in your stats/charts.

Go to your FreeRADIUS configuration directory (usually /etc/raddb or /etc/freeradius).
cd sites-enabled
ln -s ../sites-available/status status
Restart FreeRADIUS.
You should be able to test with the radclient as follows...

echo "Message-Authenticator = 0x00, FreeRADIUS-Statistics-Type = 31, Response-Packet-Type = Access-Accept" | \
radclient -x localhost:18121 status adminsecret

Note that adminsecret is the default secret key in status_server. Change if you've modified this.

SNMP ExtendAgent

Copy the freeradius shell script, to the desired host.

wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/freeradius.sh -O /etc/snmp/freeradius.sh

Make the script executable
```
chmod +x /etc/snmp/freeradius.sh
```
If you've made any changes to the FreeRADIUS status_server config (secret key, port, etc.) edit freeradius.sh and adjust the config variable accordingly.

Edit your snmpd.conf file and add:

extend freeradius /etc/snmp/freeradius.sh

Restart snmpd on the host in question.

The application should be auto-discovered as described at the top of the page. If it is not, please follow the steps set out under SNMP Extend heading top of page.

Install the script to your agent

wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/freeradius.sh -O /usr/lib/check_mk_agent/local/freeradius.sh`

Make the script executable

chmod +x /usr/lib/check_mk_agent/local/freeradius.sh

If you've made any changes to the FreeRADIUS status_server config (secret key, port, etc.) edit freeradius.sh and adjust the config variable accordingly.
Edit the freeradius.sh script and set the variable 'AGENT' to '1' in the config.
