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. |
