telegraf_plugins_extra is override when multiple call

[sinc59]

Hello, i use this role with multiple groups (postgres_database, rabbitmq) For this, i use groups_vars files to specify extra_plugins (group_vars/postgres_database, group_vars/rabbitmq) These files contains:

• group_vars/postgres_database:

telegraf_plugins_extra:
    - plugin: postgresql
      config:
          - address = "postgres://user:password@localhost/postgres"

• group_vars/rabbitmq

  telegraf_plugins_extra:
  - plugin: rabbitmq
    config:
      - url = "http://localhost:15672"

If a server is one two roles (database and rabbitmq), the file /etc/telegraf/telegraf.d/extra-plugins.conf contain only the rabbitmq.

Do you know how i can aggregate this two have the postgresql and rabbitmq in this server ?

Best regards

@sinc59 did you take a look at http://docs.ansible.com/ansible/latest/intro_configuration.html#hash-behaviour ? you can try hash_behaviour = merge, but be care to not merge other settings.

Same issue.

I think you could use filename directive to generate different file names:

• group_vars/postgres_database:

  telegraf_plugins_extra:
  - plugin: postgresql
    filename: postgresql
    config:
        - address = "postgres://user:password@localhost/postgres"

• group_vars/rabbitmq

  telegraf_plugins_extra:
  - plugin: rabbitmq
    filename: rabbitmq
    config:
      - url = "http://localhost:15672"

This was solved in 0.9.0. See https://github.com/dj-wasabi/ansible-telegraf/pull/46.

You will need to change your config to a hash instead of a list, and need hash_behaviour=merge in your ansible.cfg.

• group_vars/postgres_database:

telegraf_plugins_extra:
  postgresql:
    config:
      - address = "postgres://user:password@localhost/postgres"

• group_vars/rabbitmq

  telegraf_plugins_extra:
  rabbitmq:
  config:
    - url = "http://localhost:15672"
