Monasca DevStack Plugin

The Monasca DevStack plugin works on Ubuntu 16.04 (Xenial) though note issues and workarounds noted below under 'Using Vagrant' if using a virtualbox vm image.

Running the Monasca DevStack plugin requires a machine with 10GB of RAM.

Directions for installing and running Devstack can be found here:

http://docs.openstack.org/developer/devstack/

To run Monasca in DevStack, do the following three steps.

1. Clone the DevStack repo.

   git clone https://git.openstack.org/openstack-dev/devstack

2. Add the following to the DevStack local.conf file in the root of the devstack directory. You may need to create the local.conf if it does not already exist.

   # BEGIN DEVSTACK LOCAL.CONF CONTENTS

   local DATABASE_PASSWORD=secretdatabase RABBIT_PASSWORD=secretrabbit ADMIN_PASSWORD=secretadmin SERVICE_PASSWORD=secretservice SERVICE_TOKEN=111222333444

   LOGFILE=$DEST/logs/stack.sh.log LOGDIR=$DEST/logs LOG_COLOR=False

   # The following two variables allow switching between Java and Python for the implementations # of the Monasca API and the Monasca Persister. If these variables are not set, then the # default is to install the Python implementations of both the Monasca API and the Monasca Persister.

   # Uncomment one of the following two lines to choose Java or Python for the Monasca API. MONASCA_API_IMPLEMENTATION_LANG=${MONASCA_API_IMPLEMENTATION_LANG:-java} # MONASCA_API_IMPLEMENTATION_LANG=${MONASCA_API_IMPLEMENTATION_LANG:-python}

   # Uncomment of the following two lines to choose Java or Python for the Monasca Pesister. MONASCA_PERSISTER_IMPLEMENTATION_LANG=${MONASCA_PERSISTER_IMPLEMENTATION_LANG:-java} # MONASCA_PERSISTER_IMPLEMENTATION_LANG=${MONASCA_PERSISTER_IMPLEMENTATION_LANG:-python}

   # Uncomment one of the following two lines to choose either InfluxDB or Vertica. MONASCA_METRICS_DB=${MONASCA_METRICS_DB:-influxdb} # MONASCA_METRICS_DB=${MONASCA_METRICS_DB:-vertica}

   # This line will enable all of Monasca. enable_plugin monasca-api git://git.openstack.org/openstack/monasca-api

   # END DEVSTACK LOCAL.CONF CONTENTS

3. Run './stack.sh' from the root of the devstack directory.

If you want to run Monasca with the bare mininum of OpenStack components you can add the following two lines to the local.conf file.

disable_all_services
enable_service rabbit mysql key

If you also want the Tempest tests to be installed then add tempest

enable_service rabbit mysql key tempest

To enable Horizon and the Monasca UI add horizon

enable_service rabbit mysql key horizon tempest

Using Vagrant

Vagrant can be used to deploy a VM with Devstack and Monasca running in it using the Vagrantfile. After installing Vagrant, just run the command vagrant up as usual in the ../monasca-api/devstack directory.

N.B. If you are running with virtualbox you may find that the ./stack.sh fails with the filesystem becoming read only. There is a work around:

1. vagrant up --no-provision && vagrant halt
2. open virtualbox gui
3. open target vm settings and change storage controller from SCSI to SATA
4. vagrant up

Enable Vertica as the Metrics DB using Vagrant

Monasca supports using both InfluxDB and Vertica for storing metrics and alarm state history. InfluxDB is enabled by default in the DevStack environment.

Vertica is a commercial database from Hewlett Packard Enterprise. A free Community Edition (CE) installer is available for download.

To enable Vertica, do the following:

1. Register and download the Vertica Debian installer from https://my.vertica.com/download/vertica/community-edition/ and put it in your home directory. Unfortunately, there isn't a URL that the DevStack installer can automatically use, so it must be downloaded seperately, and put in a location where the installer can find it when it runs. The installer assumes this location is your home directory. When using Vagrant, your home directory will normally be mounted inside the VM as "/vagrant_home".

2. Modify the environment variable MONASCA_METRICS_DB in the local.conf, settings or Vagrantfile file from influxdb to vertica as follows:

   MONASCA_METRICS_DB=${MONASCA_METRICS_DB:-vertica}
