## Overview{% #overview %}

This processor sends all logs or metrics (Preview (PREVIEW indicates an early access version of a major product or feature that you can opt into before its official release.)) that match the filter query to the next step in the pipeline. Logs or metrics that do not match the filter query are dropped and are not sent to any subsequent processors or destinations. **Note**: For all other processor queries, logs or metrics that don't match the query are sent to the subsequent step in the pipeline. They are not dropped.

## Setup{% #setup %}

To set up the filter processor:

- Define a **filter query**.**Notes**:
  - Logs or metrics that match the query are sent to the next component.
  - Logs or metrics that don't match the query are dropped.
