## Configuration

Edit the `python.d/rabbitmq.conf` configuration file using `edit-config` from the Netdata [config
directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md), which is typically at `/etc/netdata`.

```bash
cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/rabbitmq.conf
```

When no configuration file is found, module tries to connect to: `localhost:15672`.

```yaml
socket:
  name     : 'local'
  host     : '127.0.0.1'
  port     :  15672
  user     : 'guest'
  pass     : 'guest'
```

### Per-Queue Chart configuration

RabbitMQ users with the "monitoring" tag cannot see all queue data. You'll need a user with read permissions. 
To create a dedicated user for netdata:

```bash
rabbitmqctl add_user netdata ChangeThisSuperSecretPassword
rabbitmqctl set_permissions netdata "^$" "^$" ".*"
```

See [set_permissions](https://www.rabbitmq.com/rabbitmqctl.8.html#set_permissions) for details.

Once the user is set up, add `collect_queues_metrics: yes` to your `rabbitmq.conf`:

```yaml
local:
  name                   : 'local'
  host                   : '127.0.0.1'
  port                   :  15672
  user                   : 'netdata'
  pass                   : 'ChangeThisSuperSecretPassword'
  collect_queues_metrics : 'yes'
```
