FreeRADIUS collector
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
Metrics
All metrics have "freeradius." prefix.
Metric | Scope | Dimensions | Units |
---|---|---|---|
authentication | global | requests, responses | packets/s |
authentication_access_responses | global | accepts, rejects, challenges | packets/s |
bad_authentication | global | dropped, duplicate, invalid, malformed, unknown-types | packets/s |
proxy_authentication | global | requests, responses | packets/s |
proxy_authentication_access_responses | global | accepts, rejects, challenges | packets/s |
proxy_bad_authentication | global | dropped, duplicate, invalid, malformed, unknown-types | packets/s |
accounting | global | requests, responses | packets/s |
bad_accounting | global | dropped, duplicate, invalid, malformed, unknown-types | packets/s |
proxy_accounting | global | requests, responses | packets/s |
proxy_bad_accounting | global | dropped, duplicate, invalid, malformed, unknown-types | packets/s |
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.
Navigate to the
plugins.d
directory, usually at/usr/libexec/netdata/plugins.d/
. If that's not the case on your system, opennetdata.conf
and look for theplugins
setting under[directories]
.cd /usr/libexec/netdata/plugins.d/
Switch to the
netdata
user.sudo -u netdata -s
Run the
go.d.plugin
to debug the collector:./go.d.plugin -d -m freeradius
