Monitoring FreeRadius with Icinga2

[Jonathan Davis]

This is a brief question for those who use Icinga2 to monitor their 
FreeRadius servers.

Do you use the built in radius check command, the remote (on the radius 
server) nagios check command, a bash/python script that executes 
'radtest' remotely against the radius server (secret needs to be added 
as a variable to icinga), or something else?

If you use a bash/python script, there are a few of them out there, what 
is the lists preference?

Thank you,
  Jonathan
