you do not click Save As Default, the filter is active until you clear it or until the Management
Card restarts.
To remove an active filter, click Filter Log, then Clear Filter (Show All).
Note: Events are processed through the filter using OR logic.
• Events that you do not select from the Filter By Severity list never display in the filtered
event log, even if the event occurs in a category you selected from the Filter by Category
list.
• Events that you do not select from the Filter by Category list never display in the filtered
event log, even if devices in the category enter an alarm state you selected from the Filter by
Severity list.
To delete the log (Logs > Events > log):
To delete all events recorded in the log, click Clear Log on the Web page that displays the log. Deleted
events cannot be retrieved.
To disable the logging of events based on their assigned severity level or their event category,
see “Configuring by group” on page 72.
To configure reverse lookup (Logs > Events > reverse lookup):
Reverse lookup is disabled by default. Enable this feature unless you have no DNS server configured or
have poor network performance because of heavy network traffic.
With reverse lookup enabled, when a network-related event occurs, both the IP address and the domain
name for the networked device associated with the event are logged in the event log. If no domain name
entry exists for the device, only its IP address is logged with the event. Since domain names generally
change less frequently than IP addresses, enabling reverse lookup can improve the ability to identify
addresses of networked devices that are causing events.
To resize the event log (Logs > Events > size):
By default, the event log stores 400 events. You can change the number of events the log stores. When
you resize the event log, all existing log entries are deleted. To avoid losing log data, use FTP or SCP to
retrieve the log before you enter a new value in the Event Log Size field.
See “How to use FTP or SCP to retrieve log files” on page 54.
When the log is full, the older entries are deleted.
