How to troubleshoot not receiving logs (4295333)

RESOLUTION 1:

• Revise the IP and port and syslog protocol configuration on both the client and server side.
  When the IP is missing from the source definition, then syslog-ng will listen on all interfaces. When there is any IP address, then the source will use that IP address found on the server.
• Check the following knowledge base articles
  
  • Troubleshooting Syslog-ng
  • Troubleshooting syslog connections in syslog-ng
  • Common connection issues of syslog-ng
  • Common issues of TLS encrypted message transfer

RESOLUTION 2:   

• Disable SELinux and/or Firewall temporarily.
• Check if syslog-ng receives logs.
• In case of yes, configure SELinux/Firewall to not block syslog-ng operations.
  SELinux: Using syslog-ng with SELinux in enforcing mode
  Firewall: Most probably the source port must be enabled in the firewall. For solution check the documentation of the firewall application.
