masakari-engine recovery looking for URL endpoint for service_name='Compute Service' instead of 'nova'

[Greg Waines]

I created an AIO devstack with Masakari on current / master on Jan 26 / 2018.
Built & installed python-masakariclient
Built and installed masakarimonitors.

started the 'masakari-instancemonitor'

# CONFIGURED MASAKARI SEGMENT AND HOST
cd ~/devstack
source openrc admin demo
masakari segment-create --name segment-1 --recovery-method auto --service-type COMPUTE
masakari host-create --name devstack-masakari-louie --type COMPUTE --control-attributes SSH --segment-id segment-1

# LAUNCHED A VM
cd ~/devstack
source openrc admin demo
FLAVOR1=`nova flavor-list | awk '{if ($4 == "m1.tiny") print $2; }'`
PRIVATENETID=`neutron net-list | grep private | awk '{print $2}'`
nova boot --flavor ${FLAVOR1} --nic net-id=${PRIVATENETID} --image cirros-0.3.5-x86_64-disk --meta HA_Enabled=True vm-1-cirros

# KILLED THE VM
ps -ef | fgrep qemu
sudo kill -9 <PID>

# RECEIVED instancemonitor's NOTIFICATION to masakari-engine

However I get the following error in masakari-engine, when the masakari-engine attempts to do the VM Recovery

Jan 26 19:41:28 devstack-masakari-louie masakari-engine[11795]: 2018-01-26 19:41:28.968 TRACE masakari.engine.drivers.taskflow.driver EndpointNotFound: publicURL endpoint for compute service named Compute Service not found

Why is masakari-engine looking for a publicURL endpoint for service_type=’compute’ and service_name=’Compute Service’ ?
See below that the Service Name = ‘nova’ ... NOT ‘Compute Service’

If you change the config option "nova_catalog_admin_info" from default "compute:Compute Service:publicURL" to "compute:nova:publicURL" and then restart masakari-engine service, it works as expected.

The default service name set in config option "nova_catalog_admin_info" is "Compute Service" which should be set to "nova". This change is required in masakari to resolve this issue.

    Fix default value of 'nova_catalog_admin_info'

    Devstack deploys nova service with name as 'nova' but in
    masakari.conf 'nova_catalog_admin_info' default is
    'compute:Compute Service:publicURL' which causes below error
    while executing masakari notifications:

    EndpointNotFound: publicURL endpoint for compute service named
    Compute Service not found.

    This patch fixes this issue by changing the default value of config
    option 'nova_catalog_admin_info' to 'compute:nova:publicURL'.

    NOTE:
    In real production deployment of masakari operator has to set the
    value of this config option according to the nova service name that
    he/she configures.
