VMNodeScrape

The VMNodeScrape CRD provides discovery mechanism for scraping metrics kubernetes nodes, it is useful for node exporters monitoring.

VMNodeScrape object generates part of VMAgent configuration. It has various options for scraping configuration of target (with basic auth,tls access, by specific port name etc.).

By specifying configuration at CRD, operator generates config for VMAgent and syncs it. It's useful for cadvisor scraping, node-exporter or other node-based exporters. VMAgent nodeScrapeSelector must match VMNodeScrape labels.

More information about selectors you can find in this doc.
