This example presumes:
|
||
|
|
|
||
|
|
1. You're using mogrus as logger.
|
||
|
|
|
||
|
|
2. You want to log messages from something to Mattermost.
|
||
|
|
|
||
|
|
3. You have ``SendMessage(channelID string, msg string)`` in your Mattermost's
|
||
|
|
client library for sending messages to desired channel.
|
||
|
|
|
||
|
|
4. ``cl.DebugChannelID is`` a channel ID to which mogrus will log.
|
||
|
|
|
||
|
|
Here's io.Writer-compatible struct for using with mogrus:
|
||
|
|
|
||
|
|
```
|
||
|
|
var logMessage = `Level: %s
|
||
|
|
Timestamp: %s
|
||
|
|
|
||
|
|
%s`
|
||
|
|
|
||
|
|
// MattermostChannelLogger provides io.Writer compatible interface for
|
||
|
|
// writing logs to Mattermost channel.
|
||
|
|
type MattermostChannelLogger struct{}
|
||
|
|
|
||
|
|
func (mcl MattermostChannelLogger) Write(p []byte) (n int, err error) {
|
||
|
|
// Generate eye-candy message.
|
||
|
|
pstr := string(p)
|
||
|
|
|
||
|
|
timer := regexp.MustCompile("time=\"([0-9. -:]+)\"")
|
||
|
|
timeFound := timer.FindAllStringSubmatch(pstr, -1)
|
||
|
|
time := timeFound[0][1]
|
||
|
|
|
||
|
|
levelr := regexp.MustCompile("level=([a-zA-Z]+)")
|
||
|
|
levelFound := levelr.FindAllStringSubmatch(pstr, -1)
|
||
|
|
level := levelFound[0][1]
|
||
|
|
|
||
|
|
msgr := regexp.MustCompile("msg=\"(.+)\"")
|
||
|
|
msgFound := msgr.FindAllStringSubmatch(pstr, -1)
|
||
|
|
logmsg := msgFound[0][1]
|
||
|
|
|
||
|
|
msg := fmt.Sprintf(logMessage, level, time, logmsg)
|
||
|
|
|
||
|
|
cl.SendMessage(cl.DebugChannelID, msg)
|
||
|
|
|
||
|
|
return len(p), nil
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Initialize it after connecting to Mattermost server like:
|
||
|
|
|
||
|
|
```
|
||
|
|
// Register output for logging into Mattermost's channel.
|
||
|
|
c.Log.CreateOutput("Mattermost debug channel", MattermostChannelLogger{}, false, cfg.System.Logging.Level)
|
||
|
|
```
|
||
|
|
|
||
|
|
Where ``c.Log`` is a mogrus instance, ``cfg.System.Logging.Level`` is one of logging levels ("debug", "info", "warn" or "error").
