538: ZEMS-EVT-BURST-START
proc-desc
is from ZEMS-TKN-BURST-PROC-DESC.
Cause. An event burst was detected. In terms of BDS configuration parameters, N
similar events have occurred within the T1 time interval. Similar events are those that
have the same SSID, event number, and subject. The L burst parameter defines what
“same subject” means. For a detailed description of BDS configuration parameters and
their default values, see Section 7, Burst Detection and Suppression.
Effect. Until the event burst ends, subsequent occurrences of these similar events are
counted and discarded.
Recovery. Examine the event to confirm that it is a repetitive event. If it is, suppress
the event by preventing it from being generated. Use the timestamp stored in the
BURST-TIME-START token as a unique burst ID for programmed operators that need
to verify that an event burst has ended.
If the event is useful, but not its repetition, change the event sender so it does not send
out the same event repeatedly.
If all occurrences of the bursting event are useful, the operator should change the BDS
configuration parameters so that bursts are not suppressed.
