Logrus时间戳格式

Question

I'm trying to transition from the Golang log package to Logrus. My issue is around how to customize the timestamp format of logged messages. The default is a counter of seconds since start but I want a "2016-03-24 17:10:15" format. My simple test code is:

package main

import (
        "github.com/Sirupsen/logrus"
)

func main() {
        customFormatter := new(logrus.TextFormatter)
        customFormatter.TimestampFormat = "2006-01-02 15:04:05"
        logrus.SetFormatter(customFormatter)
        logrus.Info("Hello Walrus")
}

This compiles and runs fine but the timestamp format is unchanged. Can anyone offer some insight into why it isn't working?

Thanks

I believe you want to set the following field to true to enable the timestamp when running it yourself with a TTY attached.

From the logrus.TextFormatter documentation:

// Enable logging the full timestamp when a TTY is attached instead of just
// the time passed since beginning of execution.
FullTimestamp bool

Tweaking your provided example:

package main

import (
    "github.com/Sirupsen/logrus"
)

func main() {
    customFormatter := new(logrus.TextFormatter)
    customFormatter.TimestampFormat = "2006-01-02 15:04:05"
    logrus.SetFormatter(customFormatter)
    logrus.Info("Hello Walrus before FullTimestamp=true")
    customFormatter.FullTimestamp = true
    logrus.Info("Hello Walrus after FullTimestamp=true")
}

Produces:

$ go run main.go
INFO[0000] Hello Walrus before FullTimestamp=true
INFO[2016-03-24 20:18:56] Hello Walrus after FullTimestamp=true
