+=========================
+Ussuri Project Priorities
+=========================
+
+List of priorities the Monasca drivers team is prioritizing in Ussuri.
+
+The owners listed are responsible for tracking the status of that work and
+helping get that work done. They are not the only contributors to this work,
+and not necessarily doing most of the coding!
+
+The implementation progress on these priorities and other identified important
+tasks is tracked in `this board`_.

+Details
+~~~~~~~
+
+New thresholding engine
+--------------------------------------------
+
+`Faust library`_ has been evaluated and the prototype of the thresholding
+engine based on this library has been implemented. The goal of this effort is
+to implement the new thresholding engine for Monasca to replace Apache Storm
+Java application.
+
+.. _Faust library: https://faust.readthedocs.io
+
+Monasca Events Agent
+--------------------
+
+The goal is to implement Monasca Events Listener which will publish Openstack
+notifications and events from third party applications to Monasca Events API.
+`Specification`_ listing existing requirements and proposed implementation
+has been written up in the past.
+
+.. _Specification: http://specs.openstack.org/openstack/monasca-specs/specs/stein/approved/monasca-events-listener.html
+
+IPv6 Support
+------------
+
+It is the community wide goal to `support IPv6-Only Deployments`_.

+
+InfluxDB HA Setup
+-----------------
+
+Story: https://storyboard.openstack.org/#!/story/2005620
+
+Query Logs API
+--------------
+
+`Add support`_ for querying ElasticSearch via the Monasca Log API to support tenant
+scoped access to logs.
+
+.. _Add support: https://blueprints.launchpad.net/monasca/+spec/log-query-api
+
+Application Credentials
+-----------------------
+
+`Keystone appliction credentials <https://docs.openstack
+.org/keystone/latest/user/application_credentials.html>`_ offer the mechanism
+to allow applications to authenticate to Keystone. The ability to specify
+`access rules <http://specs.openstack
+.org/openstack/keystone-specs/specs/keystone/stein/capabilities-app-creds
+.html>`_ for application credentials has been implemented in the Train cycle.
+
+The goal of this story is to add application credentials support in
+*monasca-agent*. This will prevent the security risk of revealing OpenStack
+user's password when installing the agent on the tenants environment. The
+access rules of these application credentials should be limited to posting
+measurements. *monasca-setup* should be extended to automatically generate such
+credentials and save them in configuration file if needed.
+
+Similar task should be implemented in *monasca-grafana-datasource*.

+
+New InfluxDB Query Capabilities
+-------------------------------
+
+The goal is to extend the Monasca API to query measurements using aggregation
+functions available in InfluxDB, like e.g. DERIVATIVE(). Another goal is to
+investigate the new Flux QL to allow basic arithmetic operations between
+different measurements, e.g. (disk_used / disk_total).
