## Log Level ## Configure Log Level
The log level of etcd can be changed dynamically via the API. You can configure debug logging using the commands below. :::note
You can no longer dynamically change the log level in etcd v3.5 or later.
:::
### etcd v3.5 And Later
To configure the log level for etcd, edit the cluster YAML:
```
services:
etcd:
extra_args:
log-level: "debug"
```
### etcd v3.4 And Earlier
In earlier etcd versions, you can use the API to dynamically change the log level. Configure debug logging using the commands below:
Command:
``` ```
docker run --net=host -v $(docker inspect kubelet --format '{{ range .Mounts }}{{ if eq .Destination "/etc/kubernetes" }}{{ .Source }}{{ end }}{{ end }}')/ssl:/etc/kubernetes/ssl:ro appropriate/curl -s -XPUT -d '{"Level":"DEBUG"}' --cacert $(docker exec etcd printenv ETCDCTL_CACERT) --cert $(docker exec etcd printenv ETCDCTL_CERT) --key $(docker exec etcd printenv ETCDCTL_KEY) $(docker exec etcd printenv ETCDCTL_ENDPOINTS)/config/local/log docker run --net=host -v $(docker inspect kubelet --format '{{ range .Mounts }}{{ if eq .Destination "/etc/kubernetes" }}{{ .Source }}{{ end }}{{ end }}')/ssl:/etc/kubernetes/ssl:ro appropriate/curl -s -XPUT -d '{"Level":"DEBUG"}' --cacert $(docker exec etcd printenv ETCDCTL_CACERT) --cert $(docker exec etcd printenv ETCDCTL_CERT) --key $(docker exec etcd printenv ETCDCTL_KEY) $(docker exec etcd printenv ETCDCTL_ENDPOINTS)/config/local/log
