EMSCINFO Display Examples (With DETAIL
Option)
The EMSCINFO detail display example in Example 13-5 provides this information
about burst detection and suppression (BDS):

The SUPPRESS function is set to OFF for the primary collector using the
SUPPRESS keyword of the EMSCCTRL command (SUPPRESS OFF). Therefore,
burst detection and suppression for the primary collector has not been enabled
using the SUPPRESS ON command.

The collector’s last-recorded BDS configuration values and their meanings are not
listed because a burst filter is installed. The BDS configuration values are
displayed by the burst filter name.

The event number and subsystem ID information (shown in Example 13-3 and
Example 13-4
, where SUPPRESS = ON) are not shown.

Information about the first subject in each burst event (shown in Example 13-3 and
Example 13-4, where SUPPRESS = ON) is not shown.

The number of events discarded with each event burst is not shown.
The EMSCINFO detail display example in Example 13-5 provides this information
about pre-log filtration (PLF):

The FILTER function is set to ON for the primary collector using the FILTER
keyword of the EMSCCTRL command (FILTER ON). Therefore, pre-log filtration in
the primary collector is currently enabled.

The number of filters present is 3.

The first filter’s file name and filter type (COMPILED) are shown.

The second filter’s file name and filter type (TABLE, PASS) are shown.

The third filter’s file name and filter type (SUPPRESS) are shown. Because the
third filter is a burst filter, burst detection and suppression for the primary collector
is enabled (through the EMSCCTRL command’s FILTER keyword, not EMSCCTRL
SUPPRESS ON). SUPPRESS cannot be set to ON when a burst filter is specified
in the collector because the burst filter is already performing the BDS function.

The current BDS configuration values and their meanings are listed. The meaning
for L is “Ignore subject tokencode and value,” and its value is “ON.” Therefore, the
L parameter in the burst filter (the comparison byte length of the first subject value
in the token) was set at -1, which is permitted.

The current number of event bursts detected by the PLF burst filter (1) is shown.

The event number and subsystem ID for the single event burst are shown.

Information about the first subject in the one detected event burst is provided
(token code, length in bytes, subsystem ID, subject value). However, because the
burst filter’s L parameter was set to -1, these values are reported as zeros.

The number of events discarded with the event burst (10) is shown.
