title: Logging
weight: 110
---
The following log levels are used in Rancher:
| Name | Description |
|---------|-------------|
| `info` | Logs informational messages. This is the default log level. |
| `debug` | Logs more detailed messages that can be used to debug. |
| `trace` | Logs very detailed messages on internal functions. This is very verbose and can contain sensitive information. |
### How to configure a log level
* Kubernetes install
* Configure debug log level
```
$ KUBECONFIG=./kube_config_rancher-cluster.yml
$ kubectl -n cattle-system get pods -l app=rancher --no-headers -o custom-columns=name:.metadata.name | while read rancherpod; do kubectl -n cattle-system exec $rancherpod -c rancher -- loglevel --set debug; done
OK
OK
OK
$ kubectl -n cattle-system logs -l app=rancher -c rancher
```
* Configure info log level
```
$ KUBECONFIG=./kube_config_rancher-cluster.yml
$ kubectl -n cattle-system get pods -l app=rancher --no-headers -o custom-columns=name:.metadata.name | while read rancherpod; do kubectl -n cattle-system exec $rancherpod -c rancher -- loglevel --set info; done
OK
OK
OK
```
* Docker Install

```
$ docker exec -ti <container_id> loglevel --set debug
OK
$ docker logs -f <container_id>
```
* Configure info log level
```
$ docker exec -ti <container_id> loglevel --set info
