the trigger. For example, if you set the minimum number of packets to 1000 and
the averaging period to 10 seconds, then if less than 1000 packets are seen in the
ten second time period, this 10 second time period is not considered as data for
the trigger.
This value ensures that the trigger will not be activated during a slow period of
network activity when a particular device or station may be sending only a few
fragmented packets, but they constitute a high percentage of the total.
• “Averaging period (sec)” spinbox—allows you to set the amount of time, in
seconds, that data will be collected and averaged before a value is considered for
the trigger. Sampling is every second. Values can be from 1 to 100 (seconds).
• “Use current filter profile” checkbox—when selected, allows you to use the
current protocol filter.
IPX Server Busy
This trigger is activated when Observer sees a 9999 NCP (server busy) packet. This is
one of the first things to check when looking for NetWare slowdowns.
• “Number of server busy replies” textbox—allows you to set the number of NCP
9999 packets received in an averaging time period.
• “Minimum number of packets (trigger level)” textbox—allows you to set the
smallest number of 9999 NCP packets in the averaging period that will be
provided as data for the trigger. For example, if you set the minimum number of
packets to 1000 and the averaging period to 10 seconds, then if less than 1000
packets total are seen in the ten second time period, this 10 second time period is
not considered as data for the trigger.
This value ensures that the trigger will not be activated during a slow period of
network activity where a NetWare server may be sending only a few 9999 packets,
but they constitute a high percentage of the total. This situation would be unusual, but
you may want to deliberately set the minimum number of packets to a low threshold
to see if server busy is still showing. If so, the server is not network load bound, but
has an internal limitation that is slowing down its response to external requests.
• “Averaging period (sec)” spinbox—allows you to set the amount of time, in
seconds, that data will be collected and averaged before a value is considered for
the trigger. Sampling is every second. Values can be from 1 to 100 (seconds).
