As an administrator, you can expose a limited set of host and virtual machine (VM) metrics to a guest VM by first enabling a `downwardMetrics` feature gate and then configuring a `downwardMetrics` device.
|
|
|
|
Users can view the metrics results by using the command line or the `vm-dump-metrics tool`.
|
|
|
|
[NOTE]
|
|
====
|
|
On Red Hat Enterprise Linux (RHEL) 9, use the command line to view downward metrics. See xref:../../virt/monitoring/virt-exposing-downward-metrics.adoc#virt-viewing-downward-metrics-cli_virt-exposing-downward-metrics[Viewing downward metrics by using the command line].
|
|
|
|
The vm-dump-metrics tool is not supported on the Red Hat Enterprise Linux (RHEL) 9 platform.
