Log Manager
The Log Manager infrastructure provides
the capability to store the application log files in a centralized repository. The
centralized repository can be accessed for viewing the log files (to aid in taking
appropriate troubleshooting actions). By default, all logs are enabled and the log
files are
categorized based on module, sub-module, and severity levels. Each entry in a log
file has
important information, including module, sub-module, severity level, unit number,
and
timestamp.
Log Manager provides the list of supported
modules and sub-modules. To display the module and sub-module hierarchy, use the
logmgr hierarchy
command.
Note: You must use the exact
module names and sub-module names as listed in the log manager hierarchy for all
Log
Manager operations.
Log Manager provides the following options:
- List Logs: Allows you to list the size
of existing logs on any connected units using the
logmgr listcommand. The logs are listed separately for each unit. - Fetch Logs: Allows you to collect logs
from any connected units and store them locally using the
logmgr fetchcommand. - Display Logs: Allows you to view the fetched logs
using the
show logging debugcommand. When viewing multiple logs, the log files are merged, sorted by timestamp, and stored in a file. If a fetch operation is not run or the fetched logs have been cleared using thelogmgr clear-fetched-logscommand, only local logs are displayed. - Upload Logs: Allows you to upload
the fetched logs to an external server using the
logmgr uploadcommand. - Monitor Logs: Allows you to monitor real-time updates to the specified logs on local units.
You can use the logmgr help
command to get the details about the usage, syntax, and examples of Log Manager
commands.
The total memory reserved for all the log files in a unit is restricted to 5 MB on the RUCKUS ICX 7150 and ICX 7150-ES devices, and 10 MB for the RUCKUS ICX 7550, 7650, 7850, and 8200 devices.
