Configure CA certificate for rsyslog logging
to remote server using Transport Layer Security (TLS)
using correct path for the DefaultNetstreamDriverCAFile
global option in /etc/rsyslog.conf, for example with the following command:
echo 'global(DefaultNetstreamDriverCAFile="/etc/pki/tls/cert.pem")' >> /etc/rsyslog.conf
Replace the /etc/pki/tls/cert.pem in the above command with the path to the file with CA certificate generated for the purpose of remote logging.
