59UPS Network Management Card 2 User’s Guide
To configure reverse lookup:
Path: Logs > Events > Reverse Lookup
With reverse lookup enabled, when a network-related event occurs, both the IP address and the domain name
for the networked device 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.
Reverse lookup is disabled by default. You should not need to enable it if you have no DNS server configured
or have poor network performance because of heavy network traffic.
To resize the Event Log.
Path: Logs > Events > Size
Use Event Log Size to specify the maximum number of log entries.
Caution: When you resize the Event Log in order to specify a maximum size, all existing log entries
are deleted. To avoid losing log data, use FTP or SCP to retrieve the log first, see “How to use FTP
or SCP to retrieve log files”. When the log subsequently reaches the maximum size, the older
entries are deleted.
Data log
Path: Logs > Data > options
Use the Data Log to display measurements about the UPS, the power input to the UPS, and the ambient
temperature of the UPS and batteries.
The steps to display and resize the Data Log are the same as for the Event Log, except that you use menu
options under Data instead of Events. See “To display the Event Log” and “To resize the Event Log”.
To filter the Data Log by date or time, use the Last or From radio buttons. (The filter configuration is saved
until the
NMC restarts).To delete all data recorded in the Data Log, click Clear Data Log. Deleted data cannot
be retrieved.
To set the data collection interval (Logs > Data > Interval): Define, in the Log Interval setting, how
frequently data is searched for and stored in the Data Log. When you click Apply, the number of possible
storage days is recalculated and display at the top of the screen.
When the log is full, the oldest entries are deleted. To avoid automatic deletion of older data, see “To configure
Data Log rotation (Logs > Data > Rotation):” directly below.
Note: Because the interval specifies how often the data is recorded, the smaller the interval, the more times the
data is recorded and the larger the log file.
To configure Data Log rotation (Logs > Data > Rotation): Rotation causes the contents of the Data Log
to be appended to the file you specify by name and location. This means you can store the data before it is
deleted, see “To set the data collection interval (Logs > Data > Interval):” directly above.
Use this option to set up password-protection and other parameters.
