Instance Method Details

#create(body) ⇒ Wavefront::Response

POST /api/v2/derivedmetric Create a specific derived metric definition. Refer to the Swagger API docs for valid keys.

Parameters:

  • body (Hash) —

    description of derived metric

Returns:

Raises:

  • (ArgumentError)

def create(body)
  raise ArgumentError unless body.is_a?(Hash)
  api.post('', body, 'application/json')
end

#delete(id) ⇒ Wavefront::Response

DELETE /api/v2/derivedmetric/id Delete a specific derived metric definition. Deleting an active derived metric moves it to ‘trash’, from where it can be restored with an #undelete operation. Deleting a derived metric in ‘trash’ removes it for ever.

Parameters:

  • id (String) —

    ID of the derived metric

Returns:

  api.delete(id)
end

#describe(id, version = nil) ⇒ Wavefront::Response

GET /api/v2/derivedmetric/id Get a specific derived metric definition / Get a specific historical version of a specific derived metric definition.

Parameters:

  • id (String) —

    ID of the derived metric

  • version (Integer) (defaults to: nil) —

    version of derived metric

Returns:

  wf_version?(version) if version
  fragments = [id]
  fragments += ['history', version] if version
  api.get(fragments.uri_concat)
end

#history(id) ⇒ Wavefront::Response

GET /api/v2/derivedmetric/id/history Get the version history of a derived metric definition.

Parameters:

  • id (String) —

    ID of the derived metric

Returns:

#list(offset = 0, limit = 100) ⇒ Wavefront::Response

GET /api/v2/derivedmetric Get all derived metric definitions for a customer.

Parameters:

  • offset (Int) (defaults to: 0) —

    derived metric at which the list begins

  • limit (Int) (defaults to: 100) —

    the number of derived metrics to return

Returns:

end

#undelete(id) ⇒ Wavefront::Response

POST /api/v2/derivedmetric/id/undelete Move a derived metric definition from ‘trash’ back into active service.

Parameters:

  • id (String) —

    ID of the derived metric

end

#update(id, body, modify = true) ⇒ Wavefront::Response

PUT /api/v2/derivedmetric/id Update a specific derived metric definition.

Parameters:

  • id (String) —

    a Wavefront alert ID

  • body (Hash) —

    key-value hash of the parameters you wish to change

  • modify (true, false) (defaults to: true) —

    if true, use #describe() to get a hash describing the existing object, and modify that with the new body. If false, pass the new body straight through.

Returns:

Raises:

  • (ArgumentError)
