Set to `true` to encrypt sensitive data. If this setting is enabled, you
must also specify the `xpack.watcher.encryption_key` setting. For more
information, see
{xpack-ref}/encrypting-data.html[Encrypting sensitive data in {watcher}].

{watcher} indices (for example, `.watcher-history*`) when it determines that
they are old. The duration of {watcher} indices is determined by the
`xpack.monitoring.history.duration` setting, which defaults to 7 days. For
more information about that setting, see <>.
