The AppSignal gem is compatible out of the box with the [Ownership](https://github.com/ankane/ownership/) gem.

## Usage

When using the Ownership gem to assign ownership to specific blocks of code, the AppSignal for Ruby gem will automatically add an owner tag to the resulting sample, with the last owner that was assigned to a block of code
during that sample as the tag's value:

<CodeGroup>
  ```ruby Ruby theme={null}
  # This will set the owner tag for this sample to :growth
  owner :growth do
    crunch_user_numbers
  end
  ```
</CodeGroup>

You can use this tag to filter samples in AppSignal by the team that owns the corresponding code.

When an error is reported, the owner tag for the error sample will be set to the owner of the block of code that caused the error.

## Setting namespaces

You can also set the [`ownership_set_namespace` configuration option](/ruby/configuration/options#option-ownership_set_namespace`) to `true` in order to, alongside the owner tag, have the namespace be automatically set to the owner.

Using namespaces allows you to easily see which performance actions and errors are owned by a specific team.

Note that changing the namespace for actions and errors that have already been reported to AppSignal will cause them to be reported as new actions and errors.

## Disable integration

To disable the integration with the Ownership gem entirely, set the [`instrument_ownership` configuration option](/ruby/configuration/options#option-instrument_ownership) to `false`.
