Viewing logs for debugs enabled using distributed logger utility

The following example shows the configuration steps to generate and view debug logs using distributed logger utility.
  1. Enable debugging for a module registered with distributed logger.
    device# dlogger module sec_macsec sub-module cli sev all
device# dlogger module sec_macsec sub-module keygen sev all
device# dlogger module sec_macsec sub-module mka sev all   
device# dlogger module sec_macsec sub-module tx sev all 
device# dlogger module sec_macsec sub-module rx sev all
device# dlogger module sec_macsec sub-module pdu sev all
device# dlogger module sec_macsec sub-module stacking sev all
device# dlogger module sec_macsec sub-module platform sev all
    The logs will be generated and maintained in the Log Manager.
  2. Find the mapping of distributed logger modules to Log Manager modules and sub-modules.
    device# show dlogger module filter lm-map
Total Module 40

    You must use the exact Log manager module names and Log manager sub-module names that correspond to the distributed logger module as listed in the show dlogger module filter lm-map command output for all Log Manager operations.

    In this example for “sec_macsec” distributed logger module, the corresponding Log manager module and sub-module names are “security” and “macsec” respectively.

  3. Fetch (create a local copy) the required logs from local and remote units. 
    device# logmgr fetch security macsec all all
  4. View debug logs from the log manager.
    device# show logging debug security macsec all all
