 - `datadog_process_checks` - Array of process checks and options (DEPRECATED: use `process` under
 `datadog_checks` instead)
 - `datadog_apt_repo` - Override default Datadog `apt` repository
+- `datadog_apt_cache_valid_time` - Override the default apt cache expiration time (default 1 hour)
 - `datadog_apt_key_url` - Override default url to Datadog `apt` key
 - `datadog_apt_key_url_new` - Override default url to the new Datadog `apt` key (in the near future the `apt` repo will have to be checked against this new key instead of the current key)
 - `datadog_agent_allow_downgrade` - Set to `yes` to allow agent downgrades on apt-based platforms (use with caution, see `defaults/main.yml` for details)
