keystone.cmd.doctor.caching module¶
- keystone.cmd.doctor.caching.symptom_caching_disabled()[source]¶
- 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()[source]¶
- 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()[source]¶
- 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.
