Overview

monasca-api is a RESTful API server that is designed with a layered architecture layered architecture.

Build

Requires monasca-common from https://github.com/stackforge/monasca-common. Download and do mvn install.

mvn clean install

Usage

java -jar target/monasca-api.jar server config-file.yml

Design Overview

Architectural layers

Requests flow through the following architectural layers from top to bottom:

• Resource
  • Serves as the entrypoint into the service.
  • Responsible for handling web service requests, and performing structural request validation.
• Application
  • Responsible for providing application level implementations for specific use cases.
• Domain
  • Contains the technology agnostic core domain model and domain service definitions.
  • Responsible for upholding invariants and defining state transitions.
• Infrastructure
  • Contains technology specific implementations of domain services.

Documentation

• API Specification: /docs/monasca-api-spec.md.

python monasca api implementation

To install the python api implementation, git clone the source and run the following command::

sudo python setup.py install

If it installs successfully, you will need to make changes to the following two files to reflect your system settings, especially where kafka server is located::

/etc/monasca/monasca.ini
/etc/monasca/monasca.conf

Once the configurations are modified to match your environment, you can start up the server by following the following instructions.

To start the server, run the following command:

Running the server in foreground mode
gunicorn -k eventlet --worker-connections=2000 --backlog=1000
         --paste /etc/monasca/monasca.ini

Running the server as daemons
gunicorn -k eventlet --worker-connections=2000 --backlog=1000
         --paste /etc/monasca/monasca.ini -D

To check if the code follows python coding style, run the following command from the root directory of this project

tox -e pep8

To run all the unit test cases, run the following command from the root directory of this project

tox -e py27   (or -e py26, -e py33)
