GOWL Golang Websocket Logger

This is a simple service that will take in log messages from a websocket and log them.

Running

clone the repository
go get github.com/tdecker91/gowl

run the binary
./{GOPATH}/bin/gowl

GOWL will listen on port 8030 by default for websocket connections. It listens for json message formatted like the example below. Once it receives a message it will log it.

 {
   "message": "the log message",
   "level": "info"
 }

Example output

[INFO] 2006-01-02 15:04:05: the log message

Log levels

Supported levels are debug, info, warn, error. Error will be printed to os.Stderr and everything else will be printed to os.Stdout

Optional flags

GOWL defaults can be overridden with command line flags. Here is an example of running GOWL on a different port with a different message format.
gowl -port=9990 -format="(%L): [%M]"

Flag	Default	Description
format	[%L] %D: %M	Message format. %L = log level. %D = Date. %M = Message. Only used for the text formatter
formatter	text	gowl uses logrus as the underlying logging system. use formatter=json to output messages as json
level	info	used to set the log level that will be printed. level supported are debug, info, warn, error
port	8030	the port gowl will listen on for websocket connections
route	/	the route the websocket server will listen for. For example if route is set to “/messages” then clients should connect to “ws://{address}:{port}/messages”
timeFormat	“2006-01-02 15:04:05”	Format string for the date. Only used for the text formatter. Refer to golang’s time package for information on how to create the format string https://golang.org/pkg/time/#Time.Format
