--- title: Logging --- 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_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_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 * Configure debug log level ``` $ docker exec -ti loglevel --set debug OK $ docker logs -f ``` * Configure info log level ``` $ docker exec -ti loglevel --set info OK ```
