alarm notifications

Each netdata alarm can have its own alarm action.

The default alarm action is the script alarm-notify.sh.

This script has the following features:

1. The to line of alarms can list one or more roles.
2. Each role can correspond to multiple recipients, using multiple notification methods (email, slack, discord, twilio, pagerduty, etc).
3. Each recipient can filter severity (i.e. receive only critical notifications).
4. The special role silent can be used in alarms that should not send any kind of notification.

Notifications Configuration

Edit /etc/netdata/health_alarm_notify.conf by running /etc/netdata/edit-config health_alarm_notify.conf to configure:

1. settings per notification method

   all notification methods except email, require some configuration (i.e. API keys, tokens, destination rooms, channels, etc).

2. recipients per role per notification method

Testing Notifications

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

# become user netdata
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"
