TROUBLESHOOTING SNIPPET: SETUP & RETRIEVE SYSLOG REPORT FOR A DMS APPLIANCE
===========================================================================
When troubleshooting a DMS appliance (DMM or SnS), the problem may
not be easily apparent to the Support Engineer and may require
you to enable additional log levels for debugging and then retrieve
the syslogs after the problem reoccurs or can be reproduced.
The default LOG_LEVEL is ERROR. The following instructions show
you how to change the LOG_LEVEL to DEBUG.
* Changing the LOG_LEVEL should be performed on a scheduled maintenance
window so that there is no user impact while making this change.
* SSH to the DMS Appliance (DMM or SnS) to access the AAI
* Get a copy of the EXISTING SYSLOG Report. Save this SYSLOG Report
for a reference and history of the issues that were logged.
Select APPLIANCE_CONTROL
--> LOGGING_OPTIONS
--> GET_SYSLOG
--> Select Method of Retrieval
* After successfully retrieve the current SYSLOG report, Clear
the logs to start a new baseline for the problem.
Select APPLIANCE_CONTROL
--> LOGGING_OPTIONS
--> CLEAN_LOGS
--> CLEAN_TOMCAT_LOGS
* After successfully clearing the logs, change the LOG_LEVEL to
DEBUG.
Select APPLIANCE_CONTROL
--> LOGGING_OPTIONS
--> CHANGE_LOG_LEVEL
--> DEBUG
After Tomcat Restarts on the LOG_LEVEL will be DEBUG and additional
DEBUG messages will be added to the different LOG files.
* At this time, You can reproduce the problem if possible otherwise you
will need to wait for the problem to reoccur.
* After the problem has been reproduced or reoccurred, you will need to
retrieve the SYSLOG Report from the DMS appliance (DMM or SnS).
* SSH to the DMS Appliance (DMM or SnS) to access the AAI
* Get a copy of the CURRENT SYSLOG Report. Save this SYSLOG Report
for review by your support team or the Cisco TAC.
Select APPLIANCE_CONTROL
--> LOGGING_OPTIONS
