Email

Send notifications via Email using Netdata's Agent alert notification feature, which supports dozens of endpoints, user roles, and more.

Setup

Prerequisites

• A working sendmail command is required for email alerts to work. Almost all MTAs provide a sendmail interface. Netdata sends all emails as user netdata, so make sure your sendmail works for local users.
• Access to the terminal where Netdata Agent is running

Configuration

File

The configuration file name for this integration is health_alarm_notify.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config health_alarm_notify.conf

The following options can be defined for this notification

Config Options

Name	Description	Default	Required
EMAIL_SENDER	You can change EMAIL_SENDER to the email address sending the notifications.	netdata	no
SEND_EMAIL	Set SEND_EMAIL to YES	YES	yes
DEFAULT_RECIPIENT_EMAIL	Set DEFAULT_RECIPIENT_EMAIL to the email address you want the email to be sent by default. You can define multiple email addresses like this: alarms@example.com systems@example.com.	root	yes

Troubleshooting

Test Notification

You can run the following command by hand, to test alerts configuration:

# become user netdata
sudo su -s /bin/bash netdata

# enable debugging info on the console
export NETDATA_ALARM_NOTIFY_DEBUG=1

# send test alarms to sysadmin
/usr/libexec/netdata/plugins.d/alarm-notify.sh test

# send test alarms to any role
/usr/libexec/netdata/plugins.d/alarm-notify.sh test "ROLE"

Note that this will test all alert mechanisms for the selected role.
