hello [@pallepavan](https://community.dynatrace.com/user/66885)&nbsp;you can do this on a bucket level for the log data, if you defined a specific bucket where the log data goes, you can truncate or delete the bucket.

You need the&nbsp; **storage:bucket-definitions:truncate** permission to be able to do it.

In this tip you have more details to use the [Grail API](https://community.dynatrace.com/post/228896).

And for the metric you can use the [API](https://docs.dynatrace.com/docs/dynatrace-api/environment-api/metric-v2/delete-metrics). But have in mind that you can’t delete a metric if it has data points ingested within the last two hours.
