glog-gokit

This packages is a replacement for glog in projects that use the go-kit logger.

It is inspired by istio's glog package for zap: https://github.com/istio/glog

Usage

Override the official glog package with this one. This simply replaces the code in vendor/golang/glog with the code of this package.

In your Gopkg.toml:

[[override]]
  name = "github.com/golang/glog"
  source = "github.com/kubermatic/glog-gokit"

In your main.go:

// Import the package like it is original glog
import "github.com/golang/glog"


// Create go-kit logger in your main.go
logger := log.NewLogfmtLogger(log.NewSyncWriter(os.Stdout))
logger = log.With(logger, "ts", log.DefaultTimestampUTC)
logger = log.With(logger, "caller", log.DefaultCaller)
logger = level.NewFilter(logger, level.AllowAll())

// Overriding the default glog with our go-kit glog implementation.
// Thus we need to pass it our go-kit logger object.
glog.SetLogger(logger)

Setting the logger to the glog package MUST happen before using glog in any package.
