destinations (see Figure 6-29). Each of those events belongs to an event group, which can
be activated separately.
The common way to log events is to use the internal log list of the DKVM-IP8 switch. To show
the log list, click on “Event Log” on the “Maintenance” page. 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 DKVM-IP8 switch . To show
the log list, click on “Event Log” on the “Maintenance” page.
Since the DKVM-IP8 switch's system memory is used to save all the information, the maximum
number of possible log list entries is restricted to 1.000 events. Every entry that exceeds this limit
overrides the oldest one, automatically.
Warning: If the reset button on the HTML frontend is used to restart the DKVM-IP8 switch,
all logging information is saved permanently and is available after the DKVM-
IP8 switch has been started. If the DKVM-IP8 switch loses power or a hard
reset is performed, all logging data will be lost. To avoid this, use one of the
following log
methods.
NFS Logging enabled
Define a NFS server, where a directory or a static link have to be exported, to write all logging
data to a file that is located there. To write logging data from more than one DKVM-IP8 switch
devices 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 the button “Apply” ,
the NFS share will be mounted immediately. That means, the NFS share and the NFS
server must be filled with valid s ources or you will get an error message.
SMTP Logging enabled
With this option, the DKVM-IP8 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 a SMTP server,
that has to be reachable from the DKVM-IP8 switch device and that needs no authentication
at all (<serverip>:<port>).
SNMP Logging enabled
If this is activated, the DKVM-IP8 switch sends a 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 eve nt. Only authentication and host power events have an own trap
class that consists of several fields with detailed information about the
occurred event. To receive this SNMP traps, any SNMP trap listener may be used.
Here is a example of all ge nerated event and its event group.
