This will install the Java based one by default. To install the python persister rather than the java version set the variable monasca_persister_java to False.

##Java Requirements

• zookeeper_hosts - A comma seperated list of kafka hosts with optional port
• kafka_hosts - A comma seperated list of kafka hosts with optional port
• influxdb_url
• influxdb_user
• influxdb_password

##Python Requirements

Requires Variables be defined for:

• zookeeper_hosts - A comma seperated list of kafka hosts with optional port
• kafka_hosts - A comma seperated list of kafka hosts with optional port
• influxdb_host
• influxdb_user
• influxdb_password

• run_mode: One of Deploy, Stop, Install, Configure or Start. The default is Deploy which will do Install, Configure, then Start.

##Example Playbook

hosts: monasca
sudo: yes
roles:
  - {role: tkuhlman.monasca-persister,
     kafka_hosts: "{{kafka_hosts}}",
     zookeeper_hosts: "{{zookeeper_hosts}}",
     influxdb_url: "http://{{mini_mon_host}}:8086",
     influxdb_user: "{{persister_influxdb_user}}",
     influxdb_password: "{{persister_influxdb_password}}",
     tags: [persister]}

##Running with Vertica

To run with vertica you must pass in the change the variable database_type to vertica in defaults or add it in the call to the role. You can also pass in the url of your vertica database and the username/password for the monasca-persister. These do default to values if not passed in. Setting the username and password would talk the form of:

vertica_users:
  - username: mon_persister
    password: password
    role: monasca_persister
