Logging with Rsyslog

Scenario: You want to deliver your logs via TCP/syslog to a logging service on a server with Rsyslog. You can do this through your Gateway/Relay server with a little setup.

As with all Gateway/Relay logs, the logs stored on the Gateway/Relay will not include Admin UI activities, which can be accessed via the sdm audit activities command.

1. On the logging server (i.e., the target/destination to which the logs will be written), edit the /etc/rsyslog.conf file and add the following lines:

   #Provides TCP syslog reception
   
   $ModLoad imtcp
   $InputTCPServerRun 514
   # You can optionally use $InputTCPMaxSessions to specify a maximum amount of connections
   # $InputTCPMaxSessions 500
   
   # Sets up logging so that the hostname and program name are visible in order to better parse logs for sdm.
   $template RemoteLogs,"/var/log/%HOSTNAME%/%PROGRAMNAME%.log"
   *.* ?RemoteLogs

2. On the logging client (the Gateway/Relay server), edit /etc/rsyslog.d/loghost.conf and add the IP address of the logging server (the target server, not the Gateway/Relay) along with the port it is listening on:

   *.* @@192.168.1.150:514

3. On the Admin UI > Settings > Security page, select the Log Encryption & Storage tab, select Log locally on relays, and then under Local storage select syslog. Add the IP address of the logging server along with the port it is listening on:

   192.168.1.150:514

Now you have configured StrongDM to send logs to your Gateway/Relay server and then deliver them to another target service.
