Add configuration options to datadog.yml

[mr337]

The DD formula has worked great but we are needing to tweak settings within datadog.yml such as tags, collect_ec2_tags, and enable_metadata_collection.

I do see a related PR #24. Looking at how this is designed as the number of options need to get added the amount of if statements will continue to grow (https://github.com/DataDog/datadog-formula/pull/24/files#diff-14b50415a1c3f0d35d35d0e6bd0b322aR40).

Would this repo be open/interest to move datadog.yml to a jinja templated file, so an user could just plug values into pillar for arbitrary config?

Example of the test.pillar updated that would write to datadog.yml only under the dd_config block:

datadog:
  api_key: aaaaaaaabbbbbbbbccccccccdddddddd
  checks:
    process:
      init_config:
        procfs_path: /proc
      instances:
        - name: ssh
          search_string: ['sshd']
    tcp_check:
      instances:
        - host: 127.0.0.1
          name: sshd
          port: 22
  dd_config:
    - collect_ec2_tags: True
    - enable_metadata_collection: True

Hoping to get an opinion on this. Thanks!

i'm currently using the following state to use any pillar data to overwrite the config file.

/etc/datadog-agent/datadog.yaml:
  file.serialize:
    - dataset: {{ salt['pillar.get']('datadog:config') }}
    - formatter: yaml

Nice, that is way less work :D

This didn't work as well for me. Any suggestions?

# cat /etc/datadog-agent/datadog.yaml
u'api_key': u'aaaaaaaabbbbbbbbccccccccdddddddd'
