Description Lucy Bopf 2016-11-07 07:26:01 UTC

The ceilometer API now runs as an apache mod-wsgi, rather than a standalone http server. This might affect how the service is restarted, for example, it may now run under httpd, instead of `ceilometer-api`. As a result, commands such as "systemctl restart ceilometer-api.service", will now need to be updated. 

Note that restarting httpd also affects other services now, such as keystone and dashboard. This should be validated with the SME first.

Comment 1 Lucy Bopf 2016-11-07 07:28:19 UTC

Assigning to Martin for review.

Comment 3 Martin Lopes 2016-11-09 04:43:07 UTC

Checked osp10-d lab and confirmed that openstack-ceilometer-api.service is not present.

Comment 4 Martin Lopes 2016-11-09 04:50:00 UTC

Confirmed that the Ceilometer API wsgi is present on the controller: /etc/httpd/conf.d/10-ceilometer_wsgi.conf

Comment 5 Martin Lopes 2016-11-09 05:23:22 UTC

* Manual installation steps may also need to be updated. Will check with SME.

Comment 7 Martin Lopes 2016-11-10 06:45:17 UTC

Reviewed manual install steps:

* Added missing packages: openstack-utils mongodb-server puppet-mongodb python-pymongo

* Changed `openstack-ceilometer-api.service` to `httpd.service` throughout.

* Occurrences of `openstack-ceilometer-api` will still remain when the reference is to the package name, and not the service.
