### 📝 Default Metrics

Upon deploying LigningUserVault, the following metrics are automatically tracked:

| Metric                    | Type      | Description                                                                 |
| ------------------------- | --------- | --------------------------------------------------------------------------- |
| `gin_request_total`       | Counter   | Total number of requests received.                                          |
| `gin_request_uv`          | Counter   | Total number of unique IPs that have made requests.                         |
| `gin_uri_request_total`   | Counter   | Number of requests for each URI.                                            |
| `gin_request_body_total`  | Counter   | Total size of request bodies (in bytes).                                    |
| `gin_response_body_total` | Counter   | Total size of response bodies (in bytes).                                   |
| `gin_request_duration`    | Histogram | Time taken to handle each request.                                          |
| `gin_slow_request_total`  | Counter   | Number of requests that exceeded the defined threshold for processing time. |

### &#x20;⚙️ Custom Metrics

LigningUserVault also supports the addition of custom metrics tailored to specific monitoring needs. Here's an example of how a custom gauge metric can be added:

```go
goCopy codegaugeMetric := &ginmetrics.Metric{
    Type:        ginmetrics.Gauge,
    Name:        "example_gauge_metric",
    Description: "an example of gauge type metric",
    Labels:      []string{"label1"},
}

// Add metric to global monitor object
_ = ginmetrics.GetMonitor().AddMetric(gaugeMetric)
```

### 🚀 Accessing Metrics

Metrics can be accessed via the `/debug/metrics` endpoint, regardless of whether LigningUserVault is started using Docker or run locally.
