glog
====
Leveled execution logs for Go.
This is an efficient pure Go implementation of leveled logs in the
manner of the open source C++ package
http://code.google.com/p/google-glog
By binding methods to booleans it is possible to use the log package
without paying the expense of evaluating the arguments to the log.
Through the -vmodule flag, the package also provides fine-grained
control over logging at the file level.
The comment from glog.go introduces the ideas:
Package glog implements logging analogous to the Google-internal
C++ INFO/ERROR/V setup. It provides functions Info, Warning,
Error, Fatal, plus formatting variants such as Infof. It
also provides V-style logging controlled by the -v and
-vmodule=file=2 flags.
Basic examples:
glog.Info("Prepare to repel boarders")
glog.Fatalf("Initialization failed: %s", err)
See the documentation for the V function for an explanation
of these examples:
if glog.V(2) {
glog.Info("Starting transaction...")
}
glog.V(2).Infoln("Processed", nItems, "elements")
The repository contains an open source version of the log package
used inside Google. The master copy of the source lives inside
Google, not here. The code in this repo is for export only and is not itself
under development. Feature requests will be ignored.

# glog-gokit
This packages is a replacement for [glog](github.com/golang/glog)
in projects that use the [go-kit logger](https://godoc.org/github.com/go-kit/kit/log).
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`:
```toml
[[override]]
name = "github.com/golang/glog"
source = "github.com/kubermatic/glog-gokit"
```
In your `main.go`:
```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.
## Function Levels
| glog | gokit |
| ------------ | ----- |
| Info | Debug |
| InfoDepth | Debug |
| Infof | Debug |
| Infoln | Debug |
| Warning | Warn |
| WarningDepth | Warn |
| Warningf | Warn |
| Warningln | Warn |
| Error | Error |
| ErrorDepth | Error |
| Errorf | Error |
| Errorln | Error |
| Exit | Error |
| ExitDepth | Error |
| Exitf | Error |
| Exitln | Error |
| Fatal | Error |
| FatalDepth | Error |
| Fatalf | Error |
| Fatalln | Error |
This table is rather opinionated and build for use with the Kubernetes' [Go client](https://github.com/kubernetes/client-go).
