# Set Exclusion Rules

Exclusion rules let you control what logs are stored. You can access Exclusion Rules by going to **[Usage > Exclusion Rules](https://app.mezmo.com/manage/exclusion-rules).**

There are three parts to a rule.

* **Hosts** - Exclude [hosts](https://docs.mezmo.com/docs/introducing-the-agent) configured on the app.
* **Apps** - Exclude [apps](https://docs.mezmo.com/docs/filters).
* **Query** - Create a [log query](https://docs.mezmo.com/docs/filters)

You can include one or all to exclude logs.
