Almost all MTAs provide a `sendmail` interface. + +Netdata sends all emails as user `netdata`, so make sure your `sendmail` works for local users. + +email notifications look like this: + + + +## Configuration + +To edit `health_alarm_notify.conf` on your system run `/etc/netdata/edit-config health_alarm_notify.conf`. + +You can configure recipients in [`/etc/netdata/health_alarm_notify.conf`](https://github.com/netdata/netdata/blob/99d44b7d0c4e006b11318a28ba4a7e7d3f9b3bae/conf.d/health_alarm_notify.conf#L101). + +You can also configure per role recipients [in the same file, a few lines below](https://github.com/netdata/netdata/blob/99d44b7d0c4e006b11318a28ba4a7e7d3f9b3bae/conf.d/health_alarm_notify.conf#L313). + +Changes to this file do not require a Netdata restart. + +You can test your configuration by issuing the commands: + +```sh +# become user netdata +sudo su -s /bin/bash netdata + +# send a test alarm +/usr/libexec/netdata/plugins.d/alarm-notify.sh test [ROLE] +``` + +Where `[ROLE]` is the role you want to test. The default (if you don't give a `[ROLE]`) is `sysadmin`. + +Note that in versions before 1.16, the plugins.d directory may be installed in a different location in certain OSs (e.g. under `/usr/lib/netdata`). +You can always find the location of the alarm-notify.sh script in `netdata.conf`. + +## Filtering + +Every notification email (both the plain text and the rich html versions) from the Netdata agent, contain a set of custom email headers that can be used for filtering using an email client. Example: + +``` +X-Netdata-Severity: warning +X-Netdata-Alert-Name: inbound_packets_dropped_ratio +X-Netdata-Chart: net_packets.enp2s0 +X-Netdata-Family: enp2s0 +X-Netdata-Classification: System +X-Netdata-Host: winterland +X-Netdata-Role: sysadmin +``` + +## Simple SMTP transport configuration + +If you want an alternative to `sendmail` in order to have a simple MTA configuration for sending emails and auth to an existing SMTP server, you can do the following: + +- Install `msmtp`. +- Modify the `sendmail` path in `health_alarm_notify.conf` to point to the location of `msmtp`: +``` +# The full path to the sendmail command. +# If empty, the system $PATH will be searched for it. +# If not found, email notifications will be disabled (silently). +sendmail="/usr/bin/msmtp" +``` +- Login as netdata : +```sh +(sudo) su -s /bin/bash netdata +``` +- Configure `~/.msmtprc` as shown [in the documentation](https://marlam.de/msmtp/documentation/). +- Finally set the appropriate permissions on the `.msmtprc` file : +```sh +chmod 600 ~/.msmtprc +``` + + |
