EMSACOLL—Alternate Collector Program
SUPPRESS [( suppression-parameters )]
lets the default values for the burst detection and suppression parameters be
overridden with user-specified values. Using the SUPPRESS keyword causes
the alternate collector to start with BDS enabled. The absence of SUPPRESS
causes BDS to be disabled at startup unless a burst filter is specified in the
FILTER keyword.
EMSACOLL’s SUPPRESS and FILTER keywords cannot be specified
simultaneously when starting an alternate collector. If the SUPPRESS keyword
is used without any SUPPRESS parameters, BDS is enabled and its default
parameter values are used. For a detailed description about each BDS
parameter and the values, including default values, that can be used with the
SUPPRESS keyword, see Section 7, Burst Detection and Suppression
.
If the FILTER keyword’s parameters specify a burst filter and SUPPRESS is
used, the alternate collector issues an Illegal Syntax error message in its OUT
file and performs an abnormal end (ABEND).
suppression-parameters has the format
suppression-parameter [ , ... ]
where each suppression-parameter is of the form
parameter [ = ] value
where parameter is one of the BDS parameters (N, T1, T2, T3, L, S) and
value is the value you supply for that parameter. The BDS suppression
parameters are supplied in a list that is separated by commas.
The values for T1, T2, and T3 are expressed in seconds. The value for N is
expressed in events. The value for L is expressed in bytes. The value for S is
expressed in burst events. For details about these and other BDS configuration
values, see Section 7, Burst Detection and Suppression.
FILTER { filter-name | (filter-name [, filter-name ]... ) }
selects the filter or filters to be used with the pre-log filtration (PLF) feature.
Each filter-name variable is the name of a filter file. If more than one filter
is needed for the alternate collector, these filter names must be specified in
parentheses in a comma-separated list. If the specified filters are correct and
usable, using the FILTER parameter enables PLF. If FILTER is not used, the
alternate collector starts with PLF disabled, and all events are logged to disk. If
one of the filters specified is a burst filter, BDS is automatically enabled.
The named filter can be a compiled filter, a filter table, or a burst filter. If a burst
filter is named and the EMSACOLL SUPPRESS parameter is also enabled, the
alternate collector issues an Illegal Syntax error message in its OUT file and
performs an abnormal end (ABEND). No more than one burst filter can be
specified.
