#### From a specific node syslog

The CNI plugins are executed by threads in the `kubelet` process.  The CNI plugins logs end up the syslog
under the `kubelet` process. On systems with `journalctl` the following is an example command line

	FMT, log/internal
	< log;

	log, log/slog !< crypto/tls, database/sql, go/importer, testing;

	FMT, log, net
	< log/syslog;

	RUNTIME

incorrect source information for functions that wrap slog. For instance, if you
define this function in file mylog.go:

	func Infof(logger *slog.Logger, format string, args ...any) {
	    logger.Info(fmt.Sprintf(format, args...))
	}

and you call it like this in main.go:

	Infof(slog.Default(), "hello, %s", "world")

then slog will report the source file as mylog.go, not main.go.
