 # Label workers with ovnic. Metrics from only these workers are pulled.
 # node-desnity-cni on 500 nodes runs for 2 hours 15 minutes. Scraping metrics from 500 nodes for the duration of 2 hours 15 minutes is overkill.
 # So we scrape from only 10 worker nodes if the worker node count is more than 120.
