Configure log forwarders

• Define a log forwarder receiver
• Add a log forwarder
• Test log forwarders
• Access Gateway logs

Before you begin

You need the following:

• A syslog server configured to receive syslog events.
  
• Connection information for the remote logging consumer. For example:
  

  Parameter	Example
  Fully qualified IP address or DNS resolvable name of logger	192.168.1.1 my.graylog.server
  Logger protocol	TCP or UDP
  Logger listen port	5514

  The port used to communicate between Access Gateway and the logging server must be open.

  Access Gateway validates the logging server connection.

Define a log forwarder receiver

To create a log forwarder in Graylog:

1. Sign in to the Graylog console as admin.
2. Select System > Inputs.
3. Search for Syslog UDP in the Select Input dropdown list.
4. Click Launch new input.
5. Select the Global checkbox.

6. Enter a name for the forwarder in the Title field.

7. Enter a port number to use for communication between Access Gateway and the logging server in the Port field. To avoid operating system restrictions when configuring syslog input receivers, use port 2048 or above. The port must be accessible from the Access Gateway admin instance.

8. Click Save.
9. Return to the Access Gateway Admin UI console

Add a log forwarder

To add a remote logger:

1. Go to your Access Gateway instance.
2. Select Backups and Logs and Backups.
   
3. Select Log Forwarder.
4. Click (+) > Syslog remote.
5. Enter the following:

   Field	Value
   Name	The name of the forwarder.
   Feed	One of: AUDIT ACCESS MONITOR See Feed examples for details of each feed.
   Protocol	Select UDP or TCP. This protocol must match that of the log listener.
   Host	The DNS resolvable hostname or IP address of the remote Syslog listener.
   Port	The port of the remote syslog listener.

6. Click Validate Forwarder. Access Gateway attempts to validate the remote logger connection information. If required, correct any input errors. On successful validation, the Validate Forwarder button changes to Forwarder Validated.
7. Click Okay.
8. The log forwarder definition appears in the list of log forwarders. Its initial status is Testing, which changes to Valid when it passes testing.
   

Test log forwarders

To test log forwarding, you need the following:

• A configured log receiver. Follow the steps outlined in the Define a log forwarder receiver section
• A log forwarder defined in your Access Gateway node. Access loggers are the simplest to test, as they generate events based on sign in to the Access Gateway Admin UI console
• Be able to generate one or more events.

To test a log forwarder:

1. Configure a system logger in your log server.
2. Configure a log forwarder in Access Gateway, preferably an access logger.
3. Ensure your system logger is started and ready to receive events
4. Sign out and then back into the Access Gateway Admin Console.
5. Examine the log server. Multiple events should be generated resembling:
