Chapter 6 Cisco Unified Serviceability Alarms and CiscoLog Messages Cisco Unified Serviceability Alarms and CiscoLog Messages Table 6-2 Name and Severity Level and Descriptions in Error Messages (continued) Name/ Severity Level Informational (6) Debug (7) Description Informational messages are distinguished from notification in that they provide information for internal flows of the application or per-request information instead of system-wide notifications. Informational messages are used for troubleshooting by users who are familiar with the basic flows of the application. Examples: • Request received • Request was parsed successfully • Request being processed • Response sent back • Acknowledgement received • Detailed audit information Debugging messages are similar to informational messages, but provide more detail and require the user to have better knowledge of system internal processing. These messages are typically reserved for very advanced users or Cisco technical support. Examples: • Complete details for a request packet • Internal state machine state changes • Internal profiling statistics • Internal events If an application uses a default severity level to determine which messages should be logged, then it is recommended that this level be set at 5 (notice). This ensures that all messages of severity 5 or higher are logged by default. MSGNAME Field The MSGNAME field of the HEADER uniquely identifies the message within the context of a given APPNAME. A fixed severity and logical meaning is associated with a specific MSGNAME within a specific APPNAME. In other words, the same message name cannot appear with different severity or a completely different logical meaning for the same APPNAME value even if the message is originated by a different process. Message names are only unique within a given application (a given APPNAME value) unless the message is one of the standard messages. Thus, applications interpreting CiscoLog messages should be careful not to assume that a message with a given name has the same meaning for all applications that may use this message name. Indeed, if the message is not one of the standard messages, it may have a different severity and meaning in a different application. The MSGNAME field must consist of at least two characters. Acceptable characters are limited to the following ASCII decimal values: 48-57 (numbers), 65-90 (upper-case letters) and 95 (underscore). While IOS allows lower-case letters as well, the vast majority of IOS messages use only the upper-case letters. In order to be consistent with established conventions we opted to restrict the character set to upper-case letters, numbers and underscore characters.
