Collector Package for Insights for AAP

Insights Analytics Collector

This package helps with collecting data by user-defined collector methods. It packs collected data to one or more tarballs and sends them to user-defined URL.

Some data and classes has to be implemented. By function:

• persisting settings
• data like credentials, content type etc. for shipping (POST request)

By Classes:

• Collector
• Package
• collector_module:
  • functions with @register decorator, one with config=True, format='json'
  • slicing functions (optional) for splitting large data (db tables) by time intervals

Implement Collector

Collector is an Abstract class, implement abstract methods.

• _package_class: Returns class of your implementation of Package
• _is_valid_license: Check for valid license specific to your service
• _is_shipping_configured: Check if shipping to cloud is configured
• _last_gathering: returns datetime. Loading last successful run from some persistent storage
• _save_last_gather: Persisting last successful run
• _load_last_gathered_entries: Has to fill dictionary self.last_gathered_entries. Load from persistent storage Dict contains keys equal to collector's registered functions' keys (with @register decorator)
• _save_last_gathered_entries: Persisting self.last_gathered_entries

An example can be found in Test collector

Implement Package

Package is also abstract class. You have to implement basically info for POST request to cloud.

• PAYLOAD_CONTENT_TYPE: contains registered content type for cloud's ingress service
• MAX_DATA_SIZE: maximum size in bytes of uncompressed data for one tarball. Ingress limits uploads to 100MB. Defaults to 200MB.
• get_ingress_url: Cloud's ingress service URL
• _get_rh_user: User for POST request
• _get_rh_password: Password for POST request
• _get_x_rh_identity: X-RH Identity Used for local testing instead of user and password
• _get_http_request_headers: Dict with any custom headers for POST request

An example can be found in Test package

Collector module

Module with gathering functions is the main part you need to implement. It should contain functions returning data either in dict format or list of CSV files.

Function is registered by @register decorator:

from insights_analytics_collector import register

@register('json_data', '1.0', format='json', description="Data description")
def json_data(**kwargs):
    return {'my_data': 'True'}

Decorator @register has following attributes:

• key: (string) name of output file (usually the same as function name)
• version: (string) i.e. '1.0'. Version of data - added to the manifest.json for parsing on cloud's side
• description: (string) not used yet
• format: (string) Default: 'json' extension of output file, can be "json" of "csv". Also determines function output.
• config: (bool) Default: False. there has to be one function with config=True, format=json
• fnc_slicing: Intended for large data. Described in Slicing function below
• shipping_group: (string) Default: 'default'. Splits data to packages by group, if required.

from <your-namespace> import Collector  # your implementation

collector = Collector
collector.gather()
