monasca-events-api 0.0.1

# Overview

monasca-events-api is a RESTful API server that is designed with a layered architecture [layered architecture](http://en.wikipedia.org/wiki/Multilayered_architecture).

## Keystone Configuration

For secure operation of the Monasca Events API, the API must be configured to use Keystone in the configuration file under the middleware section. Monasca only works with a Keystone v3 server. The important parts of the configuration are explained below:

• serverVIP - This is the hostname or IP Address of the Keystone server

• serverPort - The port for the Keystone server

• useHttps - Whether to use https when making requests of the Keystone API

• truststore - If useHttps is true and the Keystone server is not using a certificate signed by a public CA recognized by Java, the CA certificate can be placed in a truststore so the Monasca API will trust it, otherwise it will reject the https connection. This must be a JKS truststore

• truststorePassword - The password for the above truststore

• connSSLClientAuth - If the Keystone server requires the SSL client used by the Monasca server to have a specific client certificate, this should be true, false otherwise

• keystore - The keystore holding the SSL Client certificate if connSSLClientAuth is true

• keystorePassword - The password for the keystore

• defaultAuthorizedRoles - An array of roles that authorize a user to access the complete Monasca API. User must have at least one of these roles. See below

• agentAuthorizedRoles - An array of roles that authorize only the posting of metrics. See Keystone Roles below

• adminAuthMethod - “password” if the Monasca API should adminUser and adminPassword to login to the Keystone server to check the user’s token, “token” if the Monasca API should use adminToken

• adminUser - Admin user name

• adminPassword - Admin user password

• adminProjectId - Specify the project ID the api should use to request an admin token. Defaults to the admin user’s default project. The adminProjectId option takes precedence over adminProjectName.

• adminProjectName - Specify the project name the api should use to request an admin token. Defaults to the admin user’s default project. The adminProjectId option takes precedence over adminProjectName.

• adminToken - A valid admin user token if adminAuthMethod is token

• timeToCacheToken - How long the Monasca API should cache the user’s token before checking it again

### Installation

To install the events api, git clone the source and run the following commands:

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/events_api.ini /etc/monasca/events_api.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/events_api.ini

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