Two options are currently available:
* `mode`, which specifies whether to keep log lines (`keep`, the default) or to drop them (`delete`). For specific lines this can then be overriden, see 'Patterns' below.
* `mode`, which specifies whether to keep log lines (`keep`, the default) or to drop them (`delete`). For specific lines this can then be overridden, see 'Patterns' below.
* `count`, which can be set to `all` to prefix log lines with a counter, or `none` (default) to leave them as is.
