| 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. |
