# Memory usage

### Memory usage - experimental

Memory usage is a feature that allows you to track the memory usage of your application. It uses the [measureUserAgentSpecificMemory](https://developer.mozilla.org/en-US/docs/Web/API/Performance/measureUserAgentSpecificMemory) API.<br />The SDK will collect memory usage data every interval and send it to Coralogix.<br />To enable the feature, your website needs to be in a [secure context](https://developer.mozilla.org/en-US/docs/Web/API/Performance/measureUserAgentSpecificMemory#security_requirements).

```
CoralogixRum.init({

  // ...

  memoryUsageConfig: {

    enabled: true,

    interval: 300_000, // Defaults to 5 minutes

  },

});
```

You can also manually trigger memory usage data collection.

```
CoralogixRum.measureUserAgentSpecificMemory();
```
