 | `flush_interval_sec`    | The interval for metrics emission, in seconds. If `flush_interval_sec` and `flush_interval_nsec` are either both unset or both set to `0`, the filter emits metrics immediately after each filter match. Otherwise, if either parameter is set to a non-zero value, the filter emits metrics at the specified interval. Longer intervals help lower resource consumption in high-load situations. | `0`          |                                                                                                                                                         |
