Metered Rack PDU User Guide51

To filter the log (Logs > Events > log):

• Filtering the log by date or time: To display the entire event log, or to change the number of

days or weeks for which the log displays the most recent events, select Last. Select a time range

from the drop-down menu, then click Apply. The filter configuration is saved until the Rack PDU

restarts.

To display events logged during a specific time range, select From. Specify the beginning and

ending times (using the 24-hour clock format) and dates for which to display events, then click

Apply. The filter configuration is saved until the Rack PDU restarts.

• Filtering the log by event: To specify the events that display in the log, click Filter Log. Clear

the checkbox of an event category or alarm severity level to remove it from view. Text at the

upper right corner of the event log page indicates that a filter is active.

As Administrator, click Save As Default to save this filter as the default log view for all users. If

you do not click Save As Default, the filter is active until you clear it or until the Rack PDU

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 event” on page 70.

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.

Network Port Sharing Event Logs and Traps.

Rack PDU events from guest PDUs are sent to the host PDU for inclusion into its log. The log entry will

include the Display ID of the unit that the event occurred on.

These events are then handled the same as local events from the host PDU. Therefore alarms, SNMP

traps, e-mails, Syslog, etc will support Rack PDU events and alarms from all Rack PDUs in a group.

Example event log: Rack PDU 4: Device low load.

Note: System events will only be logged for the host PDU. System events from guest PDUs will not be

logged on the host PDU.
