==== Logstash Monitoring Not Working After Upgrade

When upgrading from older versions, the built-in `logstash_system` user is
disabled for security reasons. To resume monitoring:

. Change the `logstash_system` password:
+
--
[source, sh]
---------------------------------------------------------------
PUT _xpack/security/user/logstash_system/_password
{
  "password": "newpassword"
}
---------------------------------------------------------------
//CONSOLE
--

. Re-enable the `logstash_system` user:
+
--
[source, sh]
---------------------------------------------------------------
PUT _xpack/security/user/logstash_system/_enable
---------------------------------------------------------------
//CONSOLE
--
