#### via File

The configuration file name for this integration is `health_alarm_notify.conf`.


You can edit the configuration file using the [`edit-config`](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration/README.md#edit-configuration-files) script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration/README.md#locate-your-config-directory).

```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config health_alarm_notify.conf
```

##### Examples

###### Basic Configuration



```yaml
#------------------------------------------------------------------------------
# slack (slack.com) global notification options

SEND_SLACK="YES"
SLACK_WEBHOOK_URL="https://hooks.slack.com/services/XXXXXXXX/XXXXXXXX/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" 
DEFAULT_RECIPIENT_SLACK="#alarms"

```


## 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.
