-# SMS Server Tools 3
+# SMS Server Tools 3 Agent alert notifications
+
+Learn how to send notifications to `smstools3` using Netdata's Agent alert notification feature, which supports dozens of endpoints, user roles, and more.
+
+> ### Note
+>
+> This file assumes you have read the [Introduction to Agent alert notifications](https://github.com/netdata/netdata/blob/master/health/notifications/README.md), detailing how the Netdata Agent's alert notification method works.
 
 The [SMS Server Tools 3](http://smstools3.kekekasvi.com/) is a SMS Gateway software which can send and receive short messages through GSM modems and mobile phones.
 
-To have Netdata send notifications via SMS Server Tools 3, you'll first need to [install](http://smstools3.kekekasvi.com/index.php?p=compiling) and [configure](http://smstools3.kekekasvi.com/index.php?p=configure) smsd.
+## Prerequisites
 
-Ensure that the user `netdata` can execute `sendsms`. Any user executing `sendsms` needs to:
+You will need:
 
--   Have write permissions to `/tmp` and `/var/spool/sms/outgoing`
--   Be a member of group `smsd`
+- to [install](http://smstools3.kekekasvi.com/index.php?p=compiling) and [configure](http://smstools3.kekekasvi.com/index.php?p=configure) smsd
 
-To ensure that the steps above are successful, just `su netdata` and execute `sendsms phone message`.
+- To ensure that the user `netdata` can execute `sendsms`. Any user executing `sendsms` needs to:
+  - have write permissions to `/tmp` and `/var/spool/sms/outgoing`
+  - be a member of group `smsd`
 
-You then just need to configure the recipient phone numbers in `health_alarm_notify.conf`:
+    To ensure that the steps above are successful, just `su netdata` and execute `sendsms phone message`.
+- terminal access to the Agent you wish to configure
 
-```sh
-#------------------------------------------------------------------------------
-# SMS Server Tools 3 (smstools3) global notification options
+## Configure Netdata to send alert notifications to SMS Server Tools 3
 
-# enable/disable sending SMS Server Tools 3 SMS notifications
-SEND_SMS="YES"
+> ### Info
+>
+> This file mentions editing configuration files.  
+>
+> - To edit configuration files in a safe way, we provide the [`edit config` script](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#use-edit-config-to-edit-configuration-files) located in your [Netdata config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory) (typically is `/etc/netdata`) that creates the proper file and opens it in an editor automatically.  
+> Note that to run the script you need to be inside your Netdata config directory.
+>
+> It is recommended to use this way for configuring Netdata.
+
+Edit `health_alarm_notify.conf`, changes to this file do not require restarting Netdata:
 
-# if a role's recipients are not configured, a notification will be sent to
-# this SMS channel (empty = do not send a notification for unconfigured
-# roles). Multiple recipients can be given like this: "PHONE1 PHONE2 ..."
+1. Set the path for `sendsms`, otherwise Netdata will search for it in your system `$PATH`:
 
-DEFAULT_RECIPIENT_SMS=""
+    ```conf
+    # The full path of the sendsms command (smstools3).
+    # If empty, the system $PATH will be searched for it.
+    # If not found, SMS notifications will be silently disabled.
+    sendsms="/usr/bin/sendsms"
+    ```
+
+2. Set `SEND_SMS` to `YES`.
+3. Set `DEFAULT_RECIPIENT_SMS` to the phone number you want the alert notifications to be sent to.  
+    You can define multiple phone numbers like this: `PHONE1 PHONE2`.  
+    All roles will default to this variable if left unconfigured.
+
+You can then have different phone numbers per **role**, by editing `DEFAULT_RECIPIENT_IRC` with the phone number you want, in the following entries at the bottom of the same file:
+
+```conf
+role_recipients_sms[sysadmin]="PHONE1"
+role_recipients_sms[domainadmin]="PHONE2"
+role_recipients_sms[dba]="PHONE3"
+role_recipients_sms[webmaster]="PHONE4"
+role_recipients_sms[proxyadmin]="PHONE5"
+role_recipients_sms[sitemgr]="PHONE6"
 ```
 
-Netdata uses the script `sendsms` that is installed by `smstools3` and just passes a phone number and a message to it. If `sendsms` is not in `$PATH`, you can pass its location in `health_alarm_notify.conf`:
+An example of a working configuration would be:
 
-```sh
-# The full path of the sendsms command (smstools3).
-# If empty, the system $PATH will be searched for it.
-# If not found, SMS notifications will be silently disabled.
-sendsms=""
+```conf
+#------------------------------------------------------------------------------
+# SMS Server Tools 3 (smstools3) global notification options
+SEND_SMS="YES"
+DEFAULT_RECIPIENT_SMS="1234567890"
 ```
 
+## Test the notification method
 
+To test this alert notification method refer to the ["Testing Alert Notifications"](https://github.com/netdata/netdata/blob/master/health/notifications/README.md#testing-alert-notifications) section of the Agent alert notifications page.
