+
+
+Netdata Agent's alert notification feature allows you to send custom notifications to any endpoint you choose.
+
+
+
+<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
+
+## Setup
+
+### Prerequisites
+
+#### 
+
+- 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](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config health_alarm_notify.conf
+```
+#### Options
+
+The following options can be defined for this notification
+
+<details><summary>Config Options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| SEND_CUSTOM | Set `SEND_CUSTOM` to YES | YES | yes |
+| DEFAULT_RECIPIENT_CUSTOM | This value is dependent on how you handle the `${to}` variable inside the `custom_sender()` function. |  | yes |
+| custom_sender() | You can look at the other senders in `/usr/libexec/netdata/plugins.d/alarm-notify.sh` for examples of how to modify the function in this configuration file. |  | no |
+
+##### DEFAULT_RECIPIENT_CUSTOM
+
+All roles will default to this variable if left unconfigured. You can edit `DEFAULT_RECIPIENT_CUSTOM` with the variable you want, in the following entries at the bottom of the same file:
+```
+role_recipients_custom[sysadmin]="systems"
+role_recipients_custom[domainadmin]="domains"
+role_recipients_custom[dba]="databases systems"
+role_recipients_custom[webmaster]="marketing development"
+role_recipients_custom[proxyadmin]="proxy-admin"
+role_recipients_custom[sitemgr]="sites"
+```
+
+
+##### custom_sender()
+
+The following is a sample custom_sender() function in health_alarm_notify.conf, to send an SMS via an imaginary HTTPS endpoint to the SMS gateway:
+```
+custom_sender() {
+    # example human readable SMS
+    local msg="${host} ${status_message}: ${alarm} ${raised_for}"
+
+    # limit it to 160 characters and encode it for use in a URL
+    urlencode "${msg:0:160}" >/dev/null; msg="${REPLY}"
+
+    # a space separated list of the recipients to send alarms to
+    to="${1}"
+
+    for phone in ${to}; do
+      httpcode=$(docurl -X POST \
+            --data-urlencode "From=XXX" \
+            --data-urlencode "To=${phone}" \
+            --data-urlencode "Body=${msg}" \
+            -u "${accountsid}:${accounttoken}" \
+        https://domain.website.com/)
+
+      if [ "${httpcode}" = "200" ]; then
+        info "sent custom notification ${msg} to ${phone}"
+        sent=$((sent + 1))
+      else
+        error "failed to send custom notification ${msg} to ${phone} with HTTP error code ${httpcode}."
+      fi
+    done
+}
+```
+
+The supported variables that you can use for the function's `msg` variable are:
+

+#### Examples
+
+##### Basic Configuration
+
+
+
+```yaml
+#------------------------------------------------------------------------------
+# custom notifications
+
+SEND_CUSTOM="YES"
+DEFAULT_RECIPIENT_CUSTOM=""
+
+# The custom_sender() is a custom function to do whatever you need to do
+custom_sender() {
+    # example human readable SMS
+    local msg="${host} ${status_message}: ${alarm} ${raised_for}"
+
+    # limit it to 160 characters and encode it for use in a URL
+    urlencode "${msg:0:160}" >/dev/null; msg="${REPLY}"
+
+    # a space separated list of the recipients to send alarms to
+    to="${1}"
+
+    for phone in ${to}; do
+      httpcode=$(docurl -X POST \
+            --data-urlencode "From=XXX" \
+            --data-urlencode "To=${phone}" \
+            --data-urlencode "Body=${msg}" \
+            -u "${accountsid}:${accounttoken}" \
+        https://domain.website.com/)
+
+      if [ "${httpcode}" = "200" ]; then
+        info "sent custom notification ${msg} to ${phone}"
+        sent=$((sent + 1))
+      else
+        error "failed to send custom notification ${msg} to ${phone} with HTTP error code ${httpcode}."
+      fi
+    done
+}
+
+```
+
+
+## Troubleshooting
+
+### Test Notification
+
+You can run the following command by hand, to test alerts configuration:
+
+```bash
+# 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.
