Monasca UI

Monasca UI is implemented as a Horizon plugin that adds panels to Horizon. It is installed into devstack by the monasca-api plugin.

DevStack Deployment Set Up

• cd /opt/stack/horizon
• Install OpenStack upper-constraints requirements pip install -c https://opendev.org/openstack/requirements/raw/branch/master/upper-constraints.txt -r requirements.txt
• Clone Monasca UI: git clone https://opendev.org/openstack/monasca-ui.git
• Add git+https://opendev.org/openstack/monasca-ui.git to requirements.txt.
• Install Monasca UI required packages: pip install -r requirements.txt (monasca-client packages will be installed)
• Edit openstack_dashboard/settings.py to include the following two lines:
  • import monitoring.enabled
  • monitoring.enabled, (Add this line to the settings_utils.update_dashboards list)
• Link Monasca UI into Horizon:

ln -sf $(pwd)/../monasca-ui/monitoring/enabled/_50_admin_add_monitoring_panel.py \
    $(pwd)/openstack_dashboard/enabled/_50_admin_add_monitoring_panel.py
ln -sf $(pwd)/../monasca-ui/monitoring/conf/monitoring_policy.yaml \
    $(pwd)/openstack_dashboard/conf/monitoring_policy.yaml
ln -sfF $(pwd)/../monasca-ui/monitoring $(pwd)/monitoring

• Collect static files, run tests

python manage.py collectstatic --noinput
python manage.py compress
./run_tests.sh

• Restart apache service service apache2 restart

Development Environment Set Up

Get the Code

git clone https://opendev.org/openstack/monasca-ui.git  # clone monasca-ui
git clone https://opendev.org/openstack/horizon.git  # clone horizon
git clone https://github.com/monasca/grafana.git  # clone grafana
git clone https://github.com/openstack/monasca-grafana-datasource.git # clone grafana plugins

Set up Horizon

Since Monasca UI is a Horizon plugin, the first step is to get their development environment set up.

cd horizon
./run_tests.sh
cp openstack_dashboard/local/local_settings.py.example openstack_dashboard/local/local_settings.py

Pro Tip: Make sure you have Horizon running correctly before proceeding. For more details visit: https://docs.openstack.org/horizon/latest/#setup

Set up Monasca-UI

• Edit openstack_dashboard/local/local_settings.py to modify the OPENSTACK_HOST IP address to point to devstack.
• Add monasca-client to requirements.txt. Get the latest version from: https://pypi.org/project/python-monascaclient
• Link monasca into Horizon:

ln -sf $(pwd)/../monasca-ui/monitoring/enabled/_50_admin_add_monitoring_panel.py \
    $(pwd)/openstack_dashboard/enabled/_50_admin_add_monitoring_panel.py
ln -sf $(pwd)/../monasca-ui/monitoring/conf/monitoring_policy.yaml \
    $(pwd)/openstack_dashboard/conf/monitoring_policy.yaml
ln -sfF $(pwd)/../monasca-ui/monitoring $(pwd)/monitoring
./run_tests #load monasca-client into virtualenv

Set up Grafana 4.1

• The grafana4 branch of grafana is stable, as is master in monasca-grafana-datasource.
• Copy monasca-grafana-datasource/ into grafana/plugins/monasca-grafana-datasource/.
• Use the grafana docs to build and deploy grafana:
  • https://grafana.com/docs/project/building_from_source/
  • https://grafana.com/docs/installation/configuration/
• Copy monasca-ui/grafana-dashboards/* to /public/dashboards/ in your grafana deployment.
• Set GRAFANA_URL in the Horizon settings.
