= Setting the MetalLB logging levels
[role="_abstract"]
To manage log verbosity for the FRRouting (FRR) container, configure the `logLevel` specification. By adjusting this setting, you can reduce log volume from the default info level or increase detail for troubleshooting MetalLB configuration issues.
Gain a deeper insight into MetalLB by setting the `logLevel` to `debug`.
.Prerequisites
* You have access to the cluster as a user with the `cluster-admin` role.
* You have installed the {oc-first}.
.Procedure
. Create a file, such as `setdebugloglevel.yaml`, with content like the following example:
+
[source,yaml]
----
apiVersion: metallb.io/v1beta1
kind: MetalLB
metadata:
name: metallb
namespace: metallb-system
spec:
logLevel: debug
nodeSelector:
node-role.kubernetes.io/worker: ""
----
. Apply the configuration by entering the following command:
+
[source,terminal]
----
$ oc replace -f setdebugloglevel.yaml
----
+
[NOTE]
====
Use the `oc replace` command because the `metallb` CR was already created and you need to change only the log level.
====
. Display the names of the `speaker` pods:
+
[source,terminal]
----
$ oc get -n metallb-system pods -l component=speaker
----
+
.Example output
[source,text]
----
NAME READY STATUS RESTARTS AGE
speaker-2m9pm 4/4 Running 0 9m19s
speaker-7m4qw 3/4 Running 0 19s
speaker-szlmx 4/4 Running 0 9m19s
----
+
[NOTE]
====
Speaker and controller pods are recreated to ensure the updated logging level is applied. The logging level is modified for all the components of MetalLB.
====
