Interesting, the HA guide [2] states that memcached should be
configured with the list of hosts:
Access to Memcached is not handled by HAProxy because replicated
access is currently in an experimental state.
Instead, OpenStack services must be supplied with the full list of
hosts running Memcached.
On the other hand, it would be only one of many incorrect statements
in that guide since I've dealt with it, so maybe this is just outdated
information (although the page has been modified on July 25th). Which
OpenStack version are you deploying?

Further report!
We finally figure it out.
It because of the original memcache_server configuration which lead
to load key from the poweroff controller
configuration example:
[cache]
backend = oslo_cache.memcache_pool
enabled = True
memcache_servers = controller1:11211,controller2:11211,controller3:11211
After change the server set to contoller_vip:11211，problem solved.

Hi,
It could be a common issue between horizon and keystone.
As a temporary workaround for this, you can apply this [1] patch to
redirect admin user to the different page.

Hi,
we also had to deal with slow dashboard, in our case it was a
misconfiguration of memcached [0], [1].
Check with your configuration and make sure you use oslo.cache.
Hope this helps!

Zitat von 高松 <gaoso...@syswin.com>:
After kill one node of a cluster which consist of three nodes,
I found that Horizon based on keystone with provider set to fernet
respondes very slowly.
Admin login will cost at least 20 senconds.
And cli verbose command return show making authentication is stuck
about 5 senconds.
Any help will be appreciated.
