| `min`           | number                 | Minimum recorded value in the window (gauge, timer, and histogram metrics).                                                     |

| `avg`           | number                 | Average of recorded values in the window (gauge, timer, and histogram metrics).                                                 |

| `counter`       | number                 | Accumulated counter value for the window (counter metrics).                                                                     |
| `bins`          | array\<array\<number>> | Histogram bin counts as \[upper\_bound, count] pairs. The final bin's upper bound is 1e20, which represents infinity.           |
| `hostname`      | string                 | Server hostname. Attached to every event by default (events.attach\_hostname).                                                  |
| `environment`   | string                 | Application environment, e.g. "production". Attached to every event by default (events.attach\_environment).                    |
