Format a log record for syslognet — layout

Format a log record for syslognet. This function converts the logger log level to a log severity level according to RFC 5424 "The Syslog Protocol".

Usage

layout_syslognet(
  level,
  msg,
  namespace = NA_character_,
  .logcall = sys.call(),
  .topcall = sys.call(-1),
  .topenv = parent.frame()
)

level: log level, see log_levels() for more details
msg: string message
namespace: string referring to the logger environment / config to be used to override the target of the message record to be used instead of the default namespace, which is defined by the R package name from which the logger was called, and falls back to a common, global namespace.
.logcall: the logging call being evaluated (useful in formatters and layouts when you want to have access to the raw, unevaluated R expression)
.topcall: R expression from which the logging function was called (useful in formatters and layouts to extract the calling function's name or arguments)
.topenv: original frame of the .topcall calling function where the formatter function will be evaluated and that is used to look up the namespace as well via logger:::top_env_name

A character vector with a severity attribute.
