The
show logging command displays the following information.
| Output field | Description |
|---|---|
| Syslog logging | The state (enabled or disabled) of the Syslog buffer. |
| messages dropped | The number of Syslog messages dropped due to user-configured filters. By default, the software logs messages for all Syslog levels. You can disable individual Syslog levels, in which case the software filters out messages at those levels. Each time the software filters out a Syslog message, this counter is incremented. |
| flushes | The number of times the Syslog buffer has been cleared by the clear logging command or equivalent Web Management Interface option. |
| overruns | The number of times the dynamic log buffer has filled up and been cleared to hold new entries. For example, if the buffer is set for 100 entries, the 101st entry causes an overrun. After that, the 201st entry causes a second overrun. |
| level | The message levels that are enabled. Each letter represents a message type and is identified by the key (level code) beneath the value. If you disable logging of a message level, the code for that level is not listed. |
| messages logged | The total number of messages that have been logged since the software was loaded. |
| level code | The message levels represented by the one-letter codes. |
