Open Stack

Hi Torin,

Presently, masakari-monitors is completely broken. Extremely sorry for the inconvenience.

I think this is what is needed to make it work.
Install openstacksdk version 0.13.0.

Apply  patch: https://review.openstack.org/#/c/546492/

In this patch ,we need to bump openstacksdk version from 0.11.2 to 0.13.0.
We will merge above patch soon.

Regards,
Tushar Patil

Subject: Re: [Openstack] HA Compute & Instance Evacuation

Hi Tushar,

I followed the documentation to set up the masakari monitors, after I
installed the masakari API. None of the monitor services seem to work. I keep
getting an error: "AttributeError: 'module' object has no attribute 'URI'"
Here is the full output: http://paste.openstack.org/show/720761/
Are you aware of what causes the issue? Can you provide any example configs
for a working masakari setup?
