## Setup{% #setup %}

Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the [Autodiscovery Integration Templates](https://docs.datadoghq.com/agent/kubernetes/integrations/) for guidance on applying these instructions.

1. Run the following command to install the Agent integration:

   ```shell
   datadog-agent integration install -t datadog-cfssl==<INTEGRATION_VERSION>
   ```

1. Configure your integration similar to core [integrations](https://docs.datadoghq.com/getting_started/integrations/).

### Configuration{% #configuration %}

1. Edit the `cfssl.d/conf.yaml` file, in the `conf.d/` folder at the root of your Agent's configuration directory to start collecting your cfssl performance data. See the [sample exim.d/conf.yaml](https://github.com/DataDog/integrations-extras/blob/master/cfssl/datadog_checks/cfssl/data/conf.yaml.example) for all available configuration options.
