Neeraj commented on LOG4J2-2567:
--------------------------------
One workaround:
use "{color:#6a8759}useTlsMessageFormat{color}" = true, this has octet count
frame.
You will need to pass layout information yourself. Programmatically e.g
.addComponent(builder.newLayout({color:#6a8759}"Rfc5424Layout"{color})
.addAttribute({color:#6a8759}"useTlsMessageFormat"{color}{color:#cc7832},
{color}{color:#6a8759}"true"{color})
.addAttribute({color:#6a8759}"id"{color}{color:#cc7832},{color}{color:#6a8759}"App"{color})
.addAttribute({color:#6a8759}"mdcId"{color}{color:#cc7832},
{color}{color:#6a8759}"mdc"{color})
.addAttribute({color:#6a8759}"includeMDC"{color}{color:#cc7832},{color}{color:#6a8759}"true"{color})
.addAttribute({color:#6a8759}"facility"{color}{color:#cc7832},{color}{color:#6a8759}"LOCAL0"{color})
.addAttribute({color:#6a8759}"enterpriseNumber"{color}{color:#cc7832},{color}{color:#6a8759}"18060"{color})
.addAttribute({color:#6a8759}"useTlsMessageFormat"{color}{color:#cc7832},
{color}{color:#6a8759}"true"{color})

> using syslog-ng (3.19.1), here's what the server prints-out:
