5.5.7 Event Log
Important events like a login failure or a firmware update are logged to a selection of logging
destinations. Each of those events belongs to an event group, which can be activated
separately.
In the Event Log Settings you can choose how many log entries are shown on each page.
Furthermore, you can clear the log file here.
List logging enabled

The common way to log events is to use the internal log list of the KVM OVER IP SWITCH . To
show the log list, click on Event Log on the Maintenance page.
Since the KVM OVER IP SWITCH ’s system memory is used to save all the information, the
maximum number of possible log list entries is restricted to 1000 events. Every entry that
exceeds this limit overrides the oldest one.
NFS Logging enabled
Defines an NFS server to write all logging data to a file that is located there. To write logging
data from multiple KVM OVER IP SWITCH units to only one NFS share, you have to define a
file name that is unique for each device. When you change the NFS settings and press Apply,
the NFS share will be mounted immediately. That means, the NFS share and the NFS server
must be filled with valid sources or you will get an error.
SMTP Logging enabled
With this option, the KVM OVER IP SWITCH is able to send Emails to an address given by the
Email address text field in the Event Log Settings. These mails contain the same description
strings as the internal log file and the mail subject is filled with the event group of the occurred
log event. In order to use this log destination you have to specify an SMTP server that has to be
reachable from the KVM OVER IP SWITCH and that needs no authentication at all
(<serverip>:<port>).
SNMP Logging enabled
If this is activated, the KVM OVER IP SWITCH sends an SNMP trap to a specified destination
IP address every time a log event occurs. If the receiver requires a community string, you can
set it in the appropriate text field. Most of the event traps only contain one descriptive string with
all information about the log event. Only authentication and host power events have a trap class
that consists of several fields with detailed information about the occurred event. To receive
these SNMP traps, any SNMP trap listener may be used.
Warning In contrast to the internal log file on the KVM OVER IP SWITCH , the size of the NFS
log file is not limited. Every log event will be appended to the end of the file so it grows
continuously, so you may have to delete it or move it from time to time.
Note: If the reset button on the HTML front end is used to restart the IP ACCESS KVM
SWITCH CLASSIC all logging information is saved permanently and is available after the IP
ACCESS KVM SWITCH CLASSIC has been started. If the IP ACCESS KVM SWITCH
CLASSIC loses power or a hard reset is performed, all logging data will be lost. To avoid this,
use one of the log methods described below.
