Viewing the event log
The system event log saves all messages generated by the system for the current run cycle. The
system event log messages provide information regarding the status of the MP Router and its ports.
Use these steps to view the MP Router event log.
1. Log in to the MP Router as admin.
2. Enter the errshow command to list all the event messages, without page breaks.
Example:
There are six severity levels for event messages, ranging from Panic to Debug. The definitions shown in
Table 19 can only be used as
general troubleshooting guidelines; you should review each event
description thoroughly before taking action.
APswitch:admin> errshow -a
Table 19 Event message levels
Event level Description
0 = Panic Panic-level messages indicate that a specific software subsystem has detected
a fatal or unrecoverable error condition: for example, memory allocation
failures, system call failures. Such errors indicate either partial or complete
failure of a subsystem.
1 = Critical Critical-level messages indicate that the software has detected serious
problems that will eventually cause a partial or complete failure of a
subsystem if not corrected immediately. For example, a power supply failure
or rise in temperature must receive immediate attention. Some critical errors
might overlap in severity with panic-level messages.
2 = Error Error-level messages represent an error condition that does not impact overall
system functionality significantly. For example, error-level messages might
indicate timeouts on certain operations, failures of certain operations after
retries, invalid parameters, or failure to perform a requested operation.
3 = Warning Warning-level messages highlight a current operating condition that should
be checked to avoid a future failure. For example, a power supply failure in a
redundant system relays a warning that the system is no longer operating in
redundant mode until the failed power supply is replaced or fixed.
4 = Information Information-level messages report the current status of the system
components, other than error status: like detecting online and offline fabric
port status.
5 = Debug Used for debugging purposes.
