Configuring syslog config to connect over TCP or TLS

Jose_Sebastian · June 6, 2017, 3:29pm

Hi,
I the following section, syslog & UDP protocol seems to be the only supported protocol? Any chance TCP/TLS could be used ?

https://tyk.io/tyk-documentation/log-data/#aggregated-logs-with-syslog

Where does the syslog client run? Is it running within the application ?

Thanks
Jose

I believe TCP might work (untested), however there isn’t a TLS Dialer in our logger, see the relevant snippet here:

github.com

sirupsen/logrus/blob/master/hooks/syslog/syslog.go#L22


      
          
          
// SyslogHook to send logs via syslog.
          type SyslogHook struct {
          	Writer        *syslog.Writer
          	SyslogNetwork string
          	SyslogRaddr   string
          }
          
          
// Creates a hook to be added to an instance of logger. This is called with
          // `hook, err := NewSyslogHook("udp", "localhost:514", syslog.LOG_DEBUG, "")`
          // `if err == nil { log.Hooks.Add(hook) }`
          func NewSyslogHook(network, raddr string, priority syslog.Priority, tag string) (*SyslogHook, error) {
          	w, err := syslog.Dial(network, raddr, priority, tag)
          	return &SyslogHook{w, network, raddr}, err
          }
          
          
func (hook *SyslogHook) Fire(entry *logrus.Entry) error {
          	line, err := entry.String()
          	if err != nil {
          		fmt.Fprintf(os.Stderr, "Unable to read entry, %v", err)
          		return err
