This is a simple service that will take in log messages from a websocket and log them.
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 messageSupported levels are debug, info, warn, error. Error will be printed to os.Stderr and everything else will be printed to os.Stdout
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 |
