### TX2.action(action_name, [opts], fn)
Expose an action/function triggerable via PM2 or PM2.io

**Kind**: static method of [<code>TX2</code>](#TX2)

| Param | Type | Description |
| --- | --- | --- |
| action_name | <code>string</code> | Name of the action |
| [opts] | <code>object</code> | Optional parameter |
| fn | <code>function</code> | Function to be called |

**Example** *(Action without arguments)*  
```js
tx2.action('run_query', (cb) => {
  cb({ success: true })
})
```
**Example** *(Action with arguments)*  
```js
tx2.action('run_query', arg1, (cb) => {
  cb({ success: arg1 })
})
```
<a name="TX2.event"></a>

### TX2.event(name, data)
Sends an Event

**Kind**: static method of [<code>TX2</code>](#TX2)

| Param | Type | Description |
| --- | --- | --- |
| name | <code>string</code> | Name of the event |
| data | <code>object</code> | Metadata attached to the event |

**Example**  
```js

<a name="TX2.metric"></a>

### TX2.metric(name, [function]) ⇒ [<code>Metric</code>](#Metric)
Expose a Metric

**Kind**: static method of [<code>TX2</code>](#TX2)  
**Returns**: [<code>Metric</code>](#Metric) - A metrics object

| Param | Type | Description |
| --- | --- | --- |
| name | <code>string</code> | Name of the metric |
| [function] | <code>function</code> | Optional function to trigger every second to retrieve updated value |

**Example**  
```js
tx2.metric('metric_name', () => obj.value)
```
**Example**  
```js
tx2.metric('metric_name', 'unit', () => obj.value)
```
**Example**  
```js
let mn = tx2.metric('metric_name')
mn.set(20)
