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. |
|
|
|
|
