Golf is an MIT-licensed Go client library for servers supporting the Graylog Extended Log Format (GELF, https://www.graylog.org/resources/gelf-2/).
If you run into any issues with the library or have any feature requests, please create issues for them!
As this library is very new, the API could still change. I don't expect it to change much because I'm pretty happy with how it is now but if anyone has suggestions easier ways to use the library via API changes I would be open to it.
Test coverage is an ongoing process!
- GELF 1.1 support
- Native Go implementation
- Supports Logger-level and Message-level attributes
The recommended way to install is via http://gopkg.in
go get gopkg.in/aphistic/golf.v0
...
import "gopkg.in/aphistic/golf.v0"
Golf can also be installed the standard way as well
go get github.com/aphistic/golf
...
import "github.com/aphistic/golf"
For brevity a lot of error checking has been omitted from these examples, be sure you do your checks!
The standard way to implement the golf library is by creating a Client, connecting to a server and creating Loggers off that Client:
package main
import (
"gopkg.in/aphistic/golf.v0"
)
func main() {
c, _ := golf.NewClient()
c.Dial("udp://192.168.30.150")
l, _ := c.NewLogger()
// Attributes set at the Logger level will automatically be included
// on each message sent from that Logger. This is helpful if there's
// any consistent information you don't want to include every time you
// log a message.
l.SetAttr("facility", "golf.example")
l.SetAttr("instance_id", 12345)
for idx := 1; idx <= 10; idx++ {
l.Dbgm(map[string]interface{}{
"msg_attr1": 1234,
}, "Test message %v", idx)
}
c.Close()
}It is also possible to set a Logger as the default for the golf library so you don't need to keep track of a main Logger manually:
package main
import (
"gopkg.in/aphistic/golf.v0"
)
func main() {
c, _ := golf.NewClient()
c.Dial("udp://192.168.30.150")
l, _ := c.NewLogger()
// Set l as the default logger
golf.DefaultLogger(l)
// Attributes set at the Logger level will automatically be included
// on each message sent from that Logger. This is helpful if there's
// any consistent information you don't want to include every time you
// log a message.
l.SetAttr("facility", "golf.example")
l.SetAttr("instance_id", 12345)
for idx := 1; idx <= 10; idx++ {
// Use the default logger to send the message
golf.Dbgm(map[string]interface{}{
"msg_attr1": 1234,
}, "Test message %v", idx)
}
c.Close()
}
