System information

Observer General Options 247
SNMPv1 is, in practice, by far the most commonly-used standard; very few agents
support SNMPv2.
• “Repeat alarm notifications” spinbox—allows you to select the number of times that
Observer should send out SNMP-related alarms when the alarm has been triggered.
• “Repeat trap notifications” spinbox—allows you to select how many times to repeat
trap notifications.
While, in practice, the vast majority of notifications sent via UDP will reach their
destination, the UDP protocol, which is specified by the SNMP RFC for trap
notification, does not require or permit packets being acknowledged by the receiving
station. It is simply a matter of sound practice to repeat trap notifications several
times.
• “Request timeout period (sec)” spinbox—allows you to set the number of seconds
that SNMP Management Console will wait for an agent to respond before resending a
request.
• “Request retry count” spinbox—allows you to define how many times SNMP
Management Console will re-send a request to an agent before timing out.
• “Max data buffer (x100K) for running charts” spinbox—allows you to define how
much memory will be made available for SNMP Management Console’s chart
display.
The more memory made available, the more data points the chart display will be able
to show. Memory saved for the SNMP Management Console’s chart display;
however, will not be available for other programs or purposes.
• “Check this box to enable all optional hint messages” checkbox—if selected, allows
you to enable any optional hint messages for SNMP Management Console that you
have previously disabled.
