1. Introduction

Radar is a real-time interactive graphical application for remotely monitoring one or more Radiator Radius servers. Radar allows administrators to remotely monitor, analyze and change the behaviour of Radiator.

Radiator is a highly portable and configurable Radius server from Radiator Software Oy. (see https://radiatorsoftware.com/radiator

). Radar is a separate product (see https://radiatorsoftware.com/radar

) which may come bundled with your Radiator purchase.

Radar makes an authenticated TCP connection to one or more Radiators. It periodically checks the health of each connected server and provides tools for monitoring, analyzing and changing the behaviour of each Radiator.

Using Radar, administrators can:

Receive notification of Radiator problems by email, external programs or GUI popup windows.
View error and message logs.
Enable message logging direct to a Radar window. Temporarily turn on debugging only when it is required.
Plot over 20 statistical measures such as Total requests, Average response time etc.
Plot statistics for the server as a whole, or for individual Client, Realm, Handler, AuthBy or Host clauses.
Remotely restart Radiators.
View and Change the value of selected Radiator configuration parameters.

The rest of this document describes how to install, configure and operate Radar. The intended audience is experienced network administrators who are responsible for maintaining a Radiator installation.
