Using infra scraper will give you several advantages:

• speed - you cannot do the async and think it will speed things up to point when it's fast
• history - you can keep historical data and do the change analysis
• visualizations - not just force-directed and hive
  you just update config in ETCD on what you want to scrape

Closing as STALE.
