Trace

Package for error handling and error reporting

Read more here:

http://gravitational.com/blog/golang_error_handling/

Capture file, line and function

rt (
 "github.com/gravitational/trace"


 someFunc() error {
eturn trace.Wrap(err)



 main() {
r := someFunc()
t.Println(err.Error()) // prints file, line and function

Emit structured logs to Elastic search using udpbeat

Add trace's document template to your ElasticSearch cluster

 -XPUT 'http://localhost:9200/_template/trace' -d@udbbeat/template.json

Start udpbeat UDP logs collector and emitter

et github.com/gravitational/udpbeat
eat

Hook up logger to UDP collector

In your code, attach a logrus hook to use udpbeat:

rt (
github.com/gravitational/trace"
og "github.com/sirupsen/logrus"


 main() {
ook, err := trace.NewUDPHook()
f err != nil {
   log.Fatalf(err)

og.SetHook(hook)

Done! You will get structured logs capturing output, log and error message. You can edit udpbeat/template.json to modify emitted fields to whatever makes sense to your app.
