+# Syslog Hooks for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>
+
+## Usage
+
+```go
+import (
+ "log/syslog"
+ "github.com/sirupsen/logrus"
+ logrus_syslog "github.com/sirupsen/logrus/hooks/syslog"
+)
+
+func main() {
+ log := logrus.New()
+ hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
+
+ if err == nil {
+ log.Hooks.Add(hook)
+ }
+}
+```
+
+If you want to connect to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). Just assign empty string to the first two parameters of `NewSyslogHook`. It should look like the following.
+
+```go
+import (
+ "log/syslog"
+ "github.com/sirupsen/logrus"
+ logrus_syslog "github.com/sirupsen/logrus/hooks/syslog"
+)
+
+func main() {
+ log := logrus.New()
+ hook, err := logrus_syslog.NewSyslogHook("", "", syslog.LOG_INFO, "")
+
+ if err == nil {
+ log.Hooks.Add(hook)
+ }
+}
+```
