Sorry for the delay, different timezone huh!

Thanks a lot!
We'll try the solution!

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 é«?æ?¾ <gaosong1 at 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.
