createEmailAppender: Create e-mail appender

In ParallelLogger: Support for Parallel Computation, Logging, and Function Automation

Create e-mail appender

Description

Create e-mail appender

Usage

createEmailAppender(
  layout = layoutEmail,
  mailSettings,
  label = Sys.info()["nodename"],
  test = FALSE
)

Arguments

layout	The layout to be used by the appender.
mailSettings	Arguments to be passed to the sendmail function in the sendmailR package (except subject and msg).
label	A label to be used in the e-mail subject to identify a run. By default the name of the computer is used.
test	If TRUE, a message will be displayed on the console instead of sending an e-mail.

Details

Creates an appender that will send log events to an e-mail address using the sendmailR package. Please make sure your settings are correct by using the sendmailR package before using those settings here. ParallelLogger will not display any messages if something goes wrong when sending the e-mail.

Using GMail

To use a GMail account, make sure to enable 2-step verification on your Google account (see 'Security'). Click on 2-Step Verification, and scroll down to 'App passwords'. Here, you can create an app-specific password to be used with ParallelLogger. You can set host.name = "smtp.gmail.com:587", and be sure to use engine = "curl".

Examples

mailSettings <- list(
  from = "[e-mail]",
  to = "[e-mail]",
  engine = "curl",
  engineopts  = list(
    username = "[e-mail]",
    password = "Secret!"
  ), 
  control = list(
    host.name = "smtp.gmail.com:587"
  )
)
# Setting test to TRUE in this example so we don't really send an e-mail:
appender <- createEmailAppender(
  layout = layoutEmail,
  mailSettings = mailSettings,
  label = "My R session",
  test = TRUE
)

logger <- createLogger(name = "EMAIL", threshold = "FATAL", appenders = list(appender))
registerLogger(logger)

logFatal("Something bad")

unregisterLogger("EMAIL")
