# keystone.cmd.doctor.caching module

keystone.cmd.doctor.caching.symptom_caching_disabled()

  keystone.conf [cache] enabled is not enabled.

  Caching greatly improves the performance of keystone, and it is highly recommended that you enable it.

keystone.cmd.doctor.caching.symptom_caching_enabled_without_a_backend()

  Caching is not completely configured.

  Although caching is enabled in keystone.conf [cache] enabled, the default backend is still set to the no-op backend. Instead, configure keystone to point to a real caching backend like memcached.

keystone.cmd.doctor.caching.symptom_connection_to_memcached()

  Memcached isn’t reachable.

  Caching is enabled and the keystone.conf [cache] backend option is configured but one or more Memcached servers are not reachable or marked as dead. Please ensure keystone.conf [cache] memcache_servers is configured properly.
