# In-flight transformations

Users can sample, filter, enrich and transform log events before they reach
their final destination. You have full programmatic access to your log events
via [Vector Remap Language](https://vector.dev/docs/reference/vrl/)

For example, if you want to drop debug logs from a source before they're sent to
your SIEM, all you have to do is paste the following into the connection's
settings:

```Ttxt Text theme={null}
type = "filter"
condition = '.level != "debug"'
```

This will filter out any log events with the property `.level` set to `debug`

Some use cases:

* sample noisy logs before they hit your SIEM
* redact PII before it gets to your downstream destination
* send non-critical logs to cheap storage; replay them to your SIEM if needed
