sdlogr: logr implementation
Another implementation of logr interface with addition of systemd specific prefixes (severity levels). This logger is meant for apps/services that are started via systemd and want to send their logs to the system journal.
logr.Info and logr.Error messages are prefixed by SD_INFO and SD_ERR respectively and therefor should be easy to distinguish and filter with journalctl command.
// from systemd/sd-daemon.h
#define SD_EMERG "<0>" /* system is unusable */
#define SD_ALERT "<1>" /* action must be taken immediately */
#define SD_CRIT "<2>" /* critical conditions */
#define SD_ERR "<3>" /* error conditions */
#define SD_WARNING "<4>" /* warning conditions */
#define SD_NOTICE "<5>" /* normal but significant condition */
#define SD_INFO "<6>" /* informational */
#define SD_DEBUG "<7>" /* debug-level messages */

type Options ¶
type Options struct {
// Depth biases the assumed number of call frames to the "true" caller.
// Values less than zero will be treated as zero.
Depth int
// Verbosity tells sdlogr which V logs to produce. Higher values enable
// more logs. Info logs at or below this level will be written, while logs
// above this level will be discarded.
Verbosity int
// LogCallerInfo if this is false caller file name and line number will not be logged in logr.Info. Default is true, caller file name and line number are always logged in logr.Error.
LogCallerInfo bool
// Out where to send logs. Defaults to os.Stdout
Out io.Writer
