52. Cisco ACS
An example Syslog record from a Cisco Secure Access Control System (ACS) device looks like the following. For more information, refer to the Syslog Logging Configuration Scenario chapter in the Cisco Configuration Guide.
Log Sample
<38>Oct 16 21:01:29 10.0.1.1 CisACS_02_FailedAuth 1k1fg93nk 1 0 Message-Type=Authen failed,User-Name=John,NAS-IP-Address=10.0.1.2,AAA Server=acs01Example 241. Collecting From Cisco Secure ACS
The following configuration file instructs NXLog to accept Syslog messages on UDP port 1514. The payload is parsed as Syslog and then the ACS specific fields are extracted. The output is written to file in JSON format.
