Mail Hook for Logrus

In some deployments, you'll want to report errors by email. If you add this hook, an email will send for the following levels:

• Error
• Fatal
• Panic

The subject is of the form APPLICATION_NAME - LEVEL and the body contains the timestamp and the message.

Installation

Install the package with go:

go get github.com/zbindenren/logrus_mail

Usage

For APPLICATION_NAME, substitute a short string that will identify your application or service in the logs.

import (
  "log/syslog"
  "github.com/Sirupsen/logrus"
  "github.com/zbindenren/logrus_mail"
)

func main() {
  log       := logrus.New()
  // if you do not need authentication for your smtp host
  hook, err := logrus_mail.NewMailHook("APPLICATION_NAME", "HOST", PORT, "FROM", "TO")

  if err == nil {
    log.Hooks.Add(hook)
  }
}

Example with authentication:

  // if you need authentication for your smtp host
  hook, err := logrus_mail.NewMailAuthHook("APPLICATION_NAME", "HOST", PORT, "FROM", "TO", "USERNAME", "PASSWORD")

If you want to send mails with gmail:

 hook, err := logrus_mail.NewMailAuthHook("testapp", "smtp.gmail.com", 587, "[email protected]", "[email protected]", "user.name", "password")

If you get the following error:
