This article is intended to be a simple example of configuring AnyConnect relevant syslog messages to be sent from the ASA to a Syslog server.  The syslog server in this example is Spunk but almost any syslog server should be do the job.   The Syslog ID's used in this example are just a set I felt were sufficient for this article,  however you can view the extensive list of syslog messages available and customize to best fit your environment. 


The following are the syslogs configured in an event list on the ASA and tied to the Splunk instance.  A view in Splunk of the specific message is also shown
 The ASDM configuration is shown later as well as a captioned video demo.

ASDM Configuration

Note: For detailed configuration guidance please refer to the guides below.

ASA Configuration Guide 

ASDM Configuration Guide


  1. Define the Syslog Server

a   Configuration > Device Management > Logging > Syslog Servers




2.  Syslog Setup

a. Configuration > Device Management > Logging > Syslog Setup

Choose a system log facility for syslog servers to use as a basis to file messages. The default is LOCAL(4)20, which is what most UNIX systems expect. However, because your network devices share eight available facilities, you might need to change this value for system logs.  Source:  ASDM Online Help.


Note:  In this example. LOCAL1(17) is being used. 



3.  Create and Event List

a. Configuration > Device Management > Logging > Event Lists




4. Add the Event List to the Logging filter for Syslog

a. Configuration > Device Management > Logging > Logging Filters
