# Engine metering history

You can use the `information_schema.engine_metering_history` view to return information about each engine's FBU consumed over time in an account. See [Engine Consumption](/overview/engine-fundamentals/engine-consumption) for more details on consumption, nodes, and FBU. It is often useful to filter this view to a particular engine. In the example below, a filter is applied to look at the history of engines starting with `capacity_test_`. By default, shows hourly data from the last 30 days.

```sql theme={"theme":{"light":"github-light","dark":"github-dark"}}
SELECT
  *
FROM
  information_schema.engine_metering_history
WHERE
  engine_name LIKE 'capacity_test_%'
```

## Columns in information\_schema.engine\_metering\_history

Each row has the following columns with information about each engine.

| Column Name   | Data Type   | Description                                                                                          |
