# 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.

  1. Run ‘./stack.sh’ from the root of the devstack directory.

After finishing the installation, you can find the “Log Management” button on “Overview” of “Monitoring” tab, if you log in OpenStack as admin. At first time, you need to specify the index pattern and time-field name.

The index name is created as the following format. logs-[mini-mon tenant id]-YYYY-MM-DD For example: logs-20c4fbd37a2345dd84266dfc92da7bd1-2016-04-07

Set the value as the above to index pattern. Or you can use “*” as a wild card, like below. logs-20c4fbd37a2345dd84266dfc92da7bd1-*

Select @timestamp as time-field name.

  1. Extra settings

Using WSGI

monasca-log-api can be deployed with Apache using mod_uwsgi. By default monasca-log-api by default runs under gunicorn. If you wish to use Apache make sure that devstack/local.conf contains:

MONASCA_LOG_API_USE_MOD_WSGI=True

Actual MONASCA_LOG_API_DEPLOY value is determined using devstack`s WSGI_MODE variable. Nevertheless there are only three possible values, that MONASCA_LOG_API_DEPLOY can take:

Using Vagrant

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