Python Overview

A simple consistency check on a site can be done by doing the following when an instance of dynamo is installed:

from dynamo_consistency import config, datatypes, getsitecontents, getinventorycontents

config.CONFIG_FILE = '/path/to/config.json'
site = 'T2_US_MIT'     # For example

inventory_listing = getinventorycontents.get_inventory_tree(site)
remote_listing = getsitecontents.get_site_tree(site)

datatypes.compare(inventory_listing, remote_listing, 'results')

In this example, the list of file LFNs in the inventory and not at the site will be in results_missing.txt. The list of file LFNs at the site and not in the inventory will be in results_orphan.txt.

The actual comparison done by the production instance of dynamo has a few more filters and steps, as outlined under Comparison Script.
