Discovery Plugins

Promgen uses discovery plugins to bridge non-natively supported discovery mechanisms to Prometheus’s file configuration format. They should be registered using setuptools entry_points.

entry_points={
    'promgen.discovery': [
        'example = module.path.discovery:DiscoveryExample',
    ],
}

Plugins should inherit from DiscoveryBase, should implement farms() and fetch() methods

from promgen.discovery import DiscoveryBase

EXAMPLE = {
  'Farm-A': ['AA', 'AB', 'AC']
  'Farm-B': ['BA', 'BB', 'BC', 'BD']
}

class DiscoveryExample(DiscoveryBase):
  def fetch(self, farm_name):
      return EXAMPLE[farm_name]

  def farms(self):
      return EXAMPLE.keys()
