# 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](./vmagent.md) 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](./vmagent.md) 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](./vmagent.md#scraping).
|
|
|
|
## Specification
