System Messages
This section provides details on system messages to facilitate effective monitoring and maintenance of the system.
Information About Process Management
Process management is the infrastructure for starting and monitoring software on a router.
-
It is platform independent.
-
It provides consistent error messages across platforms running on Cisco IOS XE.
Remote Monitoring and System Messages
You can access system messages by logging in to the console through Telnet protocol and monitoring your system components remotely from any workstation that supports the Telnet protocol. While direct involvement in process management is not required, reviewing system messages regarding process failures and other issues is recommended.
How to Find Error Message Details
Provides guidance on using the Error Message Decoder tool to resolve system errors by entering specific message strings to retrieve detailed explanations and recommended troubleshooting steps.
To show further details about a process management or a syslog error message, enter the error message into the Error Message Decoder tool at: https://www.cisco.com/cgi-bin/Support/Errordecoder/index.cgi .
For example, enter the message
%PMAN-0-PROCESS_NOTIFICATION
into the tool to view an explanation of the error message and the recommended action to be taken.

The process lifecycle notification component failed, preventing proper detection of a process start and stop. This problem is likely the result of a software defect in the software subpackage. |
Note the time of the message and investigate the kernel error message logs to learn more about the problem and see if it is correctable. If the problem cannot be corrected or the logs are not helpful, copy the error message exactly as it appears on the console along with the output of the show tech-support command and provide the gathered information to a Cisco technical support representative. |

A process failure is being ignored due to the user-configured debug settings. |
If this behavior is desired and the debug settings are set according to a user's preference, no action is needed. If the appearance of this message is viewed as a problem, change the debug settings. The router is not expected to behave normally with this debug setting. Functionalities such as SSO switchover, router reloads, FRU resets, and so on will be affected. This setting should only be used in a debug scenario. |
