= Viewing {VirtProductName} logs with the CLI
|
||
|
||
You can configure the verbosity level of {VirtProductName} component logs by editing the `HyperConverged` custom resource (CR). Then, you can view logs for the component pods by using the `oc` CLI tool.
|
||
|
||
.Procedure
|
||
|
||
. To set log verbosity for specific components, open the `HyperConverged` CR in your default text editor by running the following command:
|
||
+
|
||
[source,terminal]
|
||
----
|
||
$ oc edit hyperconverged kubevirt-hyperconverged -n openshift-cnv
|
||
----
|
||
|
||
. Set the log level for one or more components by editing the `spec.logVerbosityConfig` stanza. For example:
|
||
+
|
||
[source,yaml]
|
||
----
|
||
apiVersion: hco.kubevirt.io/v1beta1
|
||
kind: HyperConverged
|
||
metadata:
|
||
name: kubevirt-hyperconverged
|
||
spec:
|
||
logVerbosityConfig:
|
||
kubevirt:
|
||
virtAPI: 5 <1>
|
||
virtController: 4
|
||
virtHandler: 3
|
||
virtLauncher: 2
|
||
virtOperator: 6
|
||
----
|
||
<1> The log verbosity value must be an integer in the range `1–9`, where a higher number indicates a more detailed log. In this example, the `virtAPI` component logs are exposed if their priority level is `5` or higher.
|
||
|
||
. Apply your changes by saving and exiting the editor.
|
||
|
||
. View a list of pods in the {VirtProductName} namespace by running the following command:
|
||
+
|
||
[source,terminal]
|
||
----
|
||
$ oc get pods -n openshift-cnv

. To view logs for a component pod, run the following command:
|
||
+
|
||
[source,terminal]
|
||
----
|
||
$ oc logs -n openshift-cnv <pod_name>
|
||
----
|
||
+
|
||
For example:
|
||
+
|
||
[source,terminal]
|
||
----
|
||
$ oc logs -n openshift-cnv virt-handler-2m86x
|
||
----
|
||
+
|
||
[NOTE]
|
||
====
|
||
If a pod fails to start, you can use the `--previous` option to view logs from the last attempt.
|
||
|
||
To monitor log output in real time, use the `-f` option.
