show logging debug

Displays the debug logs maintained in the log manager.
Syntax
show logging debug module sub-module severity unit-id date-time
Parameters
module
Displays the logs of a specified module or list of modules (separated by commas). Enter all to include all modules.
sub-module
Displays the logs of a specified sub-module or list of sub-modules (separated by commas). Enter all if multiple modules are specified. If only a single module is specified, then specify a single sub-module or list of sub-modules (separated by commas) belonging to the module.
severity
Specifies the severity level or list of severity levels (separated by commas) by which logs are displayed. Enter all to include all severity levels.
unit-id
Displays the logs of a unit or list of units (separated by commas). Enter "all" to aggregate the result from all units. If none of the units are specified, then logs of the local unit are displayed.
date-time
Displays the logs that are generated after the specified date and time. The format is month_date_hh:mm:ss:ms.
Modes

Privileged EXEC mode

Usage Guidelines

If the logs are generated using the debug commands, you must use the exact module names and sub-module names as listed in the log manager hierarchy.

If the logs are generated using distributed logger (dlogger), the modules and sub-modules must be specified based on the mapping of distributed logger modules to log manager displayed in the show dlogger module filter lm-map command output.

If a fetch operation is not run or the fetched logs have been cleared, local logs are displayed. That is, to display the local logs, you must run the logmgr clear-fetched-logs command first.

Examples

The following example displays all the logs in the fi_debug module from unit 1.
