Configuring Logging
This section describes how to modify local logging and how to set remote logging for the Core. It includes the following sections:
•  Setting Up System Logging
•  Configuring Remote Log Servers
•  Filtering Logs by Application or Process
Setting Up System Logging
You configure system logging at the top of the Logging page.
To set up logging
1. Choose Settings > System Settings: Logging to display the Logging page.
2. Under Logging Configuration, complete the configuration using the controls described in this table.
Control
Description
Minimum Severity
Select the minimum severity level for the system log messages. The log contains all messages with this severity level or higher.
Select one of the following levels from the drop-down list:
•  Emergency - The system is unusable.
•  Alert - Action must be taken immediately.
•  Critical - Conditions that affect the functionality of the Core.
•  Error - Conditions that probably affect the functionality of the Core.
•  Warning - Conditions that could affect the functionality of the Core, such as authentication failures.
•  Notice - Normal but significant conditions, such as a configuration change.
•  Info - Messages that provide general information about system operations.
Note: This control applies to the system log only. It does not apply to the user log.
Maximum Number of Log Files
Specify the maximum number of logs to store. The default value is 10.
Lines Per Log Page
Specify the number of lines per log page. The default value is 100.
Rotate Based On
The automatic rotation of system logs deletes your oldest log file, labeled as Archived log #10, pushes the current log to Archived log # 1, and starts a new current-day log file.
By default, the system rotates each log file every 24 hours or if the file size reaches 16 MBs (uncompressed). You can change this setting to rotate every week or month and you can rotate the files based on file size.
Specify one of the following rotation options:
•  Time - Select Day, Week, or Month from the drop-down list.
•  Disk Space - Specify how much disk space, in megabytes, the log uses before it rotates.
3. Click Apply to apply your changes to the running configuration.
4. Click Save to save your settings permanently.

You configure remote log servers on the Logging page.
To add or remove a log server
