+# Netdata alarm notifications
+
+The `exec` line in health configuration defines an external script that will be called once
+the alarm is triggered. The default script is **[alarm-notify.sh](alarm-notify.sh.in)**.
+
+You can change the default script globally by editing `/etc/netdata/netdata.conf`.
+
+`alarm-notify.sh` is capable of sending notifications:
+
+- to multiple recipients
+- using multiple notification methods
+- filtering severity per recipient
+
+It uses **roles**. For example `sysadmin`, `webmaster`, `dba`, etc.
+
+Each alarm is assigned to one or more roles, using the `to` line of the alarm configuration.
+Then `alarm-notify.sh` uses its own configuration file `/etc/netdata/health_alarm_notify.conf`
+the default is [here](health_alarm_notify.conf)
+(to edit it on your system run `/etc/netdata/edit-config health_alarm_notify.conf`)
+to find the destination address of the notification for each method.
+
+Each role may have one or more destinations.
+
+So, for example the `sysadmin` role may send:
+
+1. emails to admin1@example.com and admin2@example.com
+2. pushover.net notifications to USERTOKENS `A`, `B` and `C`.
+3. pushbullet.com push notifications to admin1@example.com and admin2@example.com
+4. messages to slack.com channel `#alarms` and `#systems`.
+5. messages to Discord channels `#alarms` and `#systems`.
+
+## Configuration
+
+Edit [`/etc/netdata/health_alarm_notify.conf`](health_alarm_notify.conf)
+by running `/etc/netdata/edit-config health_alarm_notify.conf`:
+
+- 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:
+
+```sh
+# 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"
+```
