appenders: {
'email': {
type: '@log4js-node/smtp', recipients: 'dev.team@company.name'
}
},
categories: { default: { appenders: [ 'email' ], level: 'error' } }
});
This configuration will send an email using the smtp server running on localhost:25
, for every log event of level ERROR
and above. The email will be sent to dev.team@company.name
, the subject will be the message part of the log event, the body of the email will be log event formatted by the basic layout function.
log4js.configure({
appenders: {
'email': {
type: '@log4js-node/smtp',
recipients: 'dev.team@company.name',
subject: 'Latest logs',
sender: 'my.application@company.name',
attachment: {
enable: true,
filename: 'latest.log',
message: 'See the attachment for the latest logs'
},
sendInterval: 3600
}
},
categories: { default: { appenders: ['email'], level: 'ERROR' } }
});
This configuration will send an email once every hour, with all the log events of level 'ERROR' and above as an attached file.
log4js.configure({
appenders: {
email: {
type: '@log4js-node/smtp', SMTP: { host: 'smtp.company.name', port: 8025 }, recipients: 'dev.team@company.name'
}
},
categories: { default: { appenders: ['email'], level: 'info' } }
});
This configuration can also be written as:
log4js.configure({
appenders: {
email: {
type: '@log4js-node/smtp',
transport: {
plugin: 'smtp',
options: {
host: 'smtp.company.name',
port: 8025
}
},
recipients: 'dev.team@company.name'
}
},
categories: {
default: { appenders: ['email'], level: 'info' }
}
});
A similar config can be used to specify a different transport plugin than smtp
. See the nodemailer
docs for more details.
