Issue/Introduction

Determining if a Validation Server is in use. 

Resolution

Check if a Radius validation server is in use from the VIP Enterprise Gateway Console by clicking the LOGS tab and viewing the server.log that corresponds to the Validation Server. All authentication requests are logged into this file, and the source IP address of the request is captured in the authentication response (and received, if DEBUG logging is enabled). This indicates active transactions to that Validation Server. For example:

AUDIT "2023-11-09 11:03:30.333 GMT-0700"  10.10.10.1 Checkpoint_VPN:1816 0 24585 "text=Access DENIED Authentication Failed. ,reason=12; Authentication Failed." Thread-6264 VSValidationEngine.c

Certain log entries are created when the server is ON, even if no authentication requests are received:

• A fresh log is created daily, beginning with this entry, indicating this server is actively ready for incoming requests:

AUDIT "2023-11-09 00:00:00.080 GMT-0700"  0.0.0.0 ACS:1813 0 0 "text=VSValidationServer.logThread() -- Log PING event happened at : Thu Nov 09 00:00:00 2023

• If the logging for the validation server is set to DEBUG, monitoring logs are written every 60 seconds that show the number of active threads:
